7 Chemical Fume Hood Safety Mistakes Students Should Avoid

Chemical fume hood safety helps students and laboratory staff reduce exposure to hazardous vapours during laboratory work. Common mistakes include ignoring airflow warnings, setting the sash incorrectly, blocking ventilation openings and using the hood to store chemicals. Understanding these risks helps students follow safer working practices.

A chemical fume hood is an engineering control designed to capture and remove hazardous airborne contaminants when properly installed, maintained and operated. However, it does not replace laboratory training, suitable personal protective equipment (PPE) or a chemical risk assessment.

1. Ignoring Fume Hood Airflow Warnings

Proper fume hood airflow is essential for effective containment. An airflow monitor or indicator can help users identify potential problems, but its presence alone does not guarantee safe operation.

What to do: Check the installed monitor before starting work. If a fume hood airflow alarm activates or airflow appears abnormal, stop work, notify the laboratory supervisor and follow the site's safety procedure.

2. Setting the Fume Hood Sash Height Incorrectly

Incorrect fume hood sash height can affect containment and increase the risk of exposure. Raising the sash beyond its designated operating position may also reduce the protection provided by the hood.

What to do: Keep the sash at the marked operating height specified by the manufacturer or laboratory procedure. Lower it when practical, especially when you are not actively working inside the hood.

3. Blocking the Fume Hood Baffles

Fume hood baffles help direct air through the enclosure. Placing bottles, equipment or other materials against these openings can disrupt airflow and compromise containment.

What to do: Keep the baffles and air slots clear. Arrange apparatus to allow air to circulate, and avoid overcrowding the work surface.

4. Leaning Into the Hood Opening

Leaning your head or upper body into a fume hood brings you closer to potentially hazardous vapours. Rapid arm movements near the opening can also disturb airflow.

What to do: Keep your face outside the enclosure and position the work well inside it. Follow the laboratory's specified working distance, commonly at least 15 cm (6 inches) behind the sash opening where applicable.

5. Neglecting Personal Protective Equipment

A fume hood is not a substitute for PPE. Suitable gloves, eye protection, laboratory clothing and footwear depend on the chemicals and procedures involved.

What to do: Follow the chemical risk assessment and safety data sheet. These fume hood safety precautions help reduce risks that engineering controls alone may not address.

6. Storing Chemicals Inside the Hood

Using a fume hood as a storage cabinet can obstruct airflow, reduce workspace and increase chemical compatibility risks. Excessive storage can also make spills harder to manage.

What to do: Keep only the materials required for the active procedure inside the hood. Store chemicals in designated locations and manage waste according to laboratory rules.

7. Skipping Cleaning and Maintenance

Residue, spills, damaged components and overdue inspections can compromise safe operation. A clean-looking hood is not necessarily functioning correctly.

What to do: Clean the work surface according to the approved procedure. Report damage, unusual airflow or alarms, and follow the scheduled inspection and maintenance programme.

How to Use a Chemical Fume Hood Safely

Follow these fume hood operating procedures before and during laboratory work:

1. Confirm that the hood is suitable for the planned chemicals and procedure.

2. Check the airflow indicator and any alarms.

3. Set the sash to the designated operating height.

4. Keep baffles clear and position equipment inside the enclosure.

5. Wear PPE specified by the risk assessment.

6. Keep your face outside the hood and avoid rapid movements.

7. Follow approved procedures for cleaning, spills and shutdown.

These chemical fume hood safety rules should form part of laboratory induction and practical training. Good laboratory chemical safety also depends on understanding chemical hazards, using compatible equipment and following local procedures.

Frequently Asked Questions

1. How can students follow chemical fume hood safety precautions?

Students should check airflow indicators, maintain the correct sash height, keep baffles unobstructed, wear appropriate PPE and follow their laboratory's operating procedures.

2. How do you know if a fume hood is working properly?

Check the installed airflow monitor and confirm that required inspections or certification are current. Do not rely on smell alone. Report alarms or suspected airflow problems to the laboratory supervisor.

3. Should a fume hood sash remain open during an experiment?

Keep the sash at its designated operating height while working. Do not raise it unnecessarily, because opening height can affect containment.

4. Can chemicals be stored inside a fume hood?

A fume hood should not be used for general chemical storage. Keep only the materials needed for the current procedure inside the enclosure.

Probe Sonicator vs. Ultrasonic Bath: Which One is Actually Destroying Your Proteins?

Sonication is widely used for cell disruption, protein extraction and laboratory sample preparation. But if your protein yield or activity is changing unexpectedly, the problem may not be the sample itself. The way ultrasonic energy is delivered can make a significant difference.

So, in the probe sonicator vs ultrasonic bath debate, which method is better for protein samples? Neither is automatically the right choice. The key factors are energy intensity, treatment time, temperature, sample volume and protein sensitivity.

Probe Sonicator vs Ultrasonic Bath: What's the Difference?

A probe sonicator delivers ultrasonic energy directly into the sample through a vibrating probe. An ultrasonic bath transfers energy through the bath liquid and into the sample container. This makes probe sonication more concentrated, while bath sonication provides more dispersed treatment.

Factor	Probe Sonicator	Ultrasonic Bath
Energy delivery	Directly into sample	Through surrounding bath
Energy concentration	Higher and localised	More dispersed
Sample control	More precise	Less direct
Multiple samples	Limited by probe setup	Can process several containers
Intensive disruption	Well suited	Generally less concentrated
Temperature control	Particularly important	Still important

iGene Labserve's probe sonicator documentation, for example, includes adjustable ultrasonic power, cycle and gap time settings, sample temperature monitoring and over-temperature protection.

Can Sonication Damage Proteins?

Yes, excessive sonication can affect protein integrity. High energy input, prolonged exposure and heat accumulation can alter sensitive proteins or reduce their functional activity. The risk depends on the protein, sample composition and processing conditions.

This is why protein sonication should be treated as an optimisation process rather than simply increasing power until the desired disruption is achieved.

Why Probe Sonication Can Be Hard on Protein Samples

The advantage of a probe sonicator is also something researchers need to manage carefully: energy is concentrated directly in the sample.

For probe sonication for protein extraction, factors such as amplitude, pulse duration, total processing time and sample temperature can influence the result. Longer treatment is not necessarily better if the additional energy only increases heating or stress on the protein.

A practical approach is to start with controlled conditions and monitor the sample rather than relying on maximum output.

Is an Ultrasonic Bath Gentler?

An ultrasonic bath delivers energy indirectly through the bath medium, making it useful when several containers need treatment or when direct probe contact isn't desirable.

However, "gentler" does not mean risk-free. Bath temperature, treatment duration, sample position and the characteristics of the equipment can all affect the actual energy reaching the sample.

iGene Labserve's ultrasonic cleaner documentation describes controlled time and temperature settings and uniform cavitation within the cleaning tank.

Ultrasonic Bath vs Probe Sonicator for Protein Samples

The right choice depends on what the laboratory is trying to achieve.

A probe sonicator may be more appropriate when:

• Concentrated ultrasonic energy is required
• Intensive cell disruption is needed
• The researcher needs closer control over treatment conditions
• Smaller sample volumes are being processed

An ultrasonic bath may be more appropriate when:

• Several samples need simultaneous treatment
• Direct probe contact isn't preferred
• The application does not require highly concentrated energy
• A less intensive treatment approach is suitable

For sensitive proteins, the choice should be based on the required level of disruption rather than simply choosing the most powerful equipment.

How to Reduce Protein Degradation During Sonication

Good protein sample preparation starts with controlling the process, not just the equipment.

1. Monitor temperature: Heat can become a problem during prolonged sonication.
2. Optimise sonication time: Use only as much treatment as the application requires.
3. Use pulsed operation where appropriate: Intervals can help limit heat accumulation.
4. Adjust energy levels: Higher power isn't automatically better.
5. Test the process at small scale: Establish suitable conditions before applying them to valuable samples.

The latest iGene Labserve probe sonicator documentation specifically includes pulse, continuous and rest operating modes, along with sample temperature monitoring and temperature alarms.

Which Sonicator Should Your Laboratory Choose?

The probe sonicator vs ultrasonic bath decision ultimately comes down to the sample and the intended application.

If your work requires concentrated energy and controlled disruption, a probe sonicator may offer the level of control you need. If you need to treat multiple samples with less direct energy delivery, an ultrasonic bath may be more suitable.

The most useful questions to ask before selecting equipment are:

• What sample volume will you process?
• How sensitive is the target protein?
• How much disruption is actually required?
• How will sample temperature be monitored?
• Do you need individual or batch processing?
• Can the equipment provide the control required for your protocol?

Conclusion

The probe sonicator vs ultrasonic bath choice isn't about finding one method that works for every protein sample. Probe sonicators provide more concentrated energy and greater control, while ultrasonic baths can offer a more dispersed approach for suitable applications.

What matters most is controlling energy, temperature and sonication time for protein samples according to the material being processed. If you're selecting equipment for protein extraction, cell disruption or other laboratory applications, discuss your sample requirements with iGene Labserve to identify a suitable sonication setup.

If you're evaluating equipment for protein extraction, cell disruption or other laboratory applications, iGene Labserve can help you assess the appropriate sonication setup based on your application and sample requirements.

Frequently Asked Questions

1. Can sonication destroy proteins?

Excessive energy, heat or prolonged treatment can affect protein stability and activity. The actual effect depends on the protein and sonication conditions.

2. Is a probe sonicator better than an ultrasonic bath for proteins?

Not universally. Probe sonicators provide more concentrated energy, while baths provide more dispersed treatment. The suitable option depends on the application and sample.

3. How long should protein samples be sonicated?

There is no single ideal duration for every protein. Treatment time should be optimised according to sample type, volume, energy level and temperature.

4. Does a probe sonicator generate heat?

Yes. Intensive ultrasonic treatment can increase sample temperature, which is why temperature monitoring and controlled treatment conditions matter.

5. Can an ultrasonic bath be used for protein samples?

Yes, depending on the application. It can be useful where less direct ultrasonic treatment or processing of multiple containers is required.

6. What should I consider before buying a sonicator?

Consider sample volume, required energy, temperature control, operating modes, processing time and whether you need direct or batch sonication.

Why Does Class II biosafety cabinet airflow velocity Drop? Causes and Checks

A change in Class II biosafety cabinet airflow velocity should not be ignored. Airflow is central to how a Class II biosafety cabinet operates and maintains its intended airflow pattern. If the reading starts to fall, the cause may be something as simple as an obstructed grille or a change in the surrounding room conditions, or it could indicate filter loading, blower performance issues or the need for professional cabinet certification.

Understanding the possible causes helps laboratory teams identify what can be checked safely and when professional assessment is required.

What Does Airflow Velocity Mean in a Class II Biosafety Cabinet?

Biosafety cabinet airflow velocity describes how quickly air moves through specific areas of the cabinet. A Class II cabinet uses both inflow velocity and downflow velocity as part of its designed airflow pattern.

The required airflow range depends on the cabinet type, model and applicable specifications. For example, Class II Type A2 cabinets listed under NSF/ANSI 49 have defined performance requirements for inflow and downflow.

Airflow should therefore be assessed against the manufacturer's specified operating range rather than a generic number found elsewhere.

Why Does Airflow Velocity Drop?

Several factors can contribute to low airflow in a biosafety cabinet. Checking the obvious causes first can help laboratory teams identify whether the problem may be related to the cabinet, its operating conditions or the surrounding environment.

1. HEPA Filter Loading

A HEPA filter collects particles as air passes through it. Over time, filter loading can increase resistance to airflow and affect cabinet performance.

A filter problem should not be addressed through an improvised replacement. The filter condition and overall cabinet performance should be assessed according to the manufacturer's procedures and applicable certification requirements.

2. Blocked Air Grilles

Blocked grilles are another possible cause of biosafety cabinet airflow problems. Equipment, containers or other materials positioned too close to the front or rear grilles can interfere with the intended air movement.

Keep the work area organised and avoid unnecessary obstruction around airflow openings.

3. Blower Performance

The blower is responsible for moving air through the cabinet. Changes in blower performance can affect airflow readings and may result from mechanical wear, electrical issues or other equipment problems.

If basic operational checks do not identify the cause, blower performance should be assessed by an appropriately qualified professional.

4. Changes Around the Cabinet

The laboratory environment can influence cabinet airflow. Nearby doors, room fans, ventilation equipment and frequent movement can disturb the air entering the cabinet.

If the airflow reading changed after the cabinet was relocated or the room ventilation was modified, the installation conditions should be reviewed as part of the investigation.

5. Sash Position and Operating Conditions

The sash should be operated at the position specified for the cabinet. An incorrect sash position can affect airflow balance and may contribute to an unusual reading or alarm.

If the cabinet displays an airflow alarm, do not simply silence or bypass it. Follow the manufacturer's instructions and investigate the reason for the alarm.

What Should You Check First?

When investigating biosafety cabinet airflow problems, follow a controlled sequence rather than immediately adjusting cabinet components:

1. Check that the sash is at the specified operating position.

2. Look for obvious obstructions around the front and rear grilles.

3. Check whether the cabinet has recently been moved.

4. Review any airflow or filter alarms.

5. Check the current reading against the manufacturer's specified range.

6. Arrange professional testing if the reading remains outside the required range.

Do not adjust the blower or alter airflow settings simply to obtain a preferred reading. Airflow is only one part of the cabinet's overall performance.

Why Is Airflow Monitoring Important?

Airflow monitoring helps laboratory teams identify changes in cabinet performance. However, an airflow reading alone does not confirm that a cabinet continues to meet all applicable performance requirements.

Professional testing may involve more than measuring airflow. Depending on the cabinet and certification requirements, assessment can include inflow and downflow measurements, HEPA filter leak testing and other checks.

This is why cabinet certification should be considered as part of the overall performance assessment rather than treating airflow velocity as an isolated measurement.

How Does Maintenance Affect Cabinet Airflow?

Regular biosafety cabinet maintenance can help identify problems before they become more disruptive to laboratory operations. Maintenance may involve checking airflow, filters, blower operation, alarms and other cabinet components according to the manufacturer's requirements.

Laboratory teams should also keep service and certification records. Comparing current results with previous measurements can make it easier to identify changes in performance.

If repeated airflow problems occur, the issue may need a broader review of the cabinet's condition, installation and suitability for the laboratory's work.

What Is a Class II A2 Biosafety Cabinet?

A Biosafety Cabinet Class II A2 is designed around a combination of inward airflow and filtered vertical airflow through the work area. Its performance depends on the cabinet design, airflow balance, filtration system and installation conditions.

When selecting or replacing a cabinet, laboratory managers should consider the intended application, required containment, available laboratory space, exhaust requirements and applicable certification standards.

For laboratories reviewing equipment options, iGene Labserve provides Class II Type A2 biosafety cabinet solutions for laboratory applications.

When Should a Biosafety Cabinet Be Professionally Checked?

Professional assessment should be considered when airflow readings remain outside the manufacturer's specified range, an airflow alarm continues, the cabinet has been relocated, a filter or blower issue is suspected, or certification is due.

The purpose of professional testing is not simply to restore an airflow number. It is to determine whether the cabinet continues to perform according to its intended specifications.

If you are reviewing different cabinet configurations, iGene Labserve also provides Class II Type B2 biosafety cabinet options for applications requiring a different exhaust arrangement.

Choosing the Right Class II Biosafety Cabinet

Airflow should be one part of the equipment-selection process, not the only factor.

Before purchasing a cabinet, laboratory managers should consider:

• The type of work performed inside the cabinet

• Required containment and protection

• Inflow and downflow requirements

• HEPA filtration

• Laboratory ventilation and installation conditions

• Exhaust requirements

• Certification requirements

• Available workspace

• Service and maintenance requirements

The right choice depends on the application and laboratory environment. A cabinet should not be selected solely because it has a particular airflow specification.

Frequently Asked Questions

What causes low airflow in a biosafety cabinet?

Possible causes include HEPA filter loading, blocked grilles, changes in room conditions, incorrect sash position and problems affecting blower performance. The actual cause needs to be established through appropriate inspection and testing.

What is the difference between inflow velocity and downflow velocity?

Inflow velocity refers to air entering the cabinet through the front access opening, while downflow velocity refers to filtered air moving vertically through the work area. Both contribute to the cabinet's designed airflow pattern.

Can I adjust the blower to increase airflow?

Airflow should not simply be increased to produce a higher reading. The cabinet should be assessed against its manufacturer's specifications and applicable certification requirements before any adjustment is made.

Does a HEPA filter affect biosafety cabinet airflow velocity?

Yes. Filter loading can increase resistance to airflow and may contribute to changes in biosafety cabinet airflow velocity. Filter condition should be assessed as part of appropriate servicing and certification.

What should I do if my biosafety cabinet shows an airflow alarm?

Follow the manufacturer's operating instructions and your laboratory's established safety procedures. Do not bypass the alarm simply to continue working. If the cause is not clear, arrange an appropriate professional assessment.

How often should a Class II biosafety cabinet be certified?

The required certification schedule depends on the applicable standards, laboratory procedures and local requirements. Certification may also be required after events such as relocation or servicing that could affect cabinet performance.

Need Help Selecting a Class II Biosafety Cabinet?

If your laboratory is reviewing Class II biosafety cabinet options, look beyond airflow numbers alone. The cabinet type, application, installation conditions, filtration, exhaust arrangement, maintenance requirements and certification all need to be considered.

iGene Labserve can help laboratory teams review suitable biosafety cabinet configurations and select equipment according to their application and laboratory requirements.

Microbiology and Molecular Biology Lab Equipment Checklist for New Labs

Setting up a new laboratory involves more than purchasing instruments and arranging them on benches. The equipment needs to match the laboratory's planned work, sample volume, safety requirements, available space and future expansion plans.

A microbiology lab equipment checklist can help laboratory managers and procurement teams identify the core instruments required before purchasing. However, not every laboratory needs the same equipment. A microbiology facility focused on culture work will have different priorities from a molecular biology laboratory performing PCR, electrophoresis or nucleic acid analysis.

For laboratories in Delhi and elsewhere in India, the practical approach is to define the workflow first and select equipment around those requirements.

What Equipment Does a New Microbiology or Molecular Biology Lab Need?

A new laboratory generally needs equipment for sample handling, controlled incubation, sterilisation, separation, storage and analysis. Microbiology laboratories may prioritise incubators, biosafety cabinets and autoclaves, while molecular biology workflows may require centrifuges, PCR systems, electrophoresis equipment and analytical instruments.

The final equipment list should therefore be based on the tests and research activities the laboratory intends to perform rather than a fixed list of instruments.

Microbiology Laboratory Equipment Checklist

The right microbiology lab equipment depends on whether the facility is handling routine culture, research, quality control or more specialised applications.

Laboratory Incubator

A laboratory incubator provides controlled temperature conditions for applications such as microbial culture and growth. iGene Labserve's bacteriological incubator range is designed for bacterial culture and controlled temperature operation, with digital temperature control and options for customised configurations.

For a new laboratory, consider:

• Required temperature range
• Chamber capacity
• Temperature uniformity
• Alarm functions
• Number of samples handled per batch
• Data monitoring requirements

Biosafety Cabinet

A biosafety cabinet should be selected according to the biological work being performed and the required level of protection. Class II cabinets are commonly used for microbiological applications where protection of the operator, product and environment is required. iGene offers Class II biosafety cabinet options, including Type A2 and Type B2 configurations.

The cabinet should not be selected simply by size or price. The laboratory's biological procedures, airflow requirements, installation conditions and exhaust arrangements need to be considered.

Laboratory Autoclave

A laboratory autoclave is used for steam sterilisation of suitable laboratory materials and equipment. iGene's vertical autoclave range is positioned for applications including microbiology laboratories and laboratory sterilisation.

Before choosing an autoclave, check:

• Chamber capacity
• Load type
• Sterilisation cycle requirements
• Available utilities
• Space for installation
• Loading and unloading requirements

Laboratory Centrifuge

A laboratory centrifuge supports sample separation and preparation across both microbiology and molecular biology workflows. The required model depends on sample volume, speed, temperature control and rotor configuration.

For applications involving temperature-sensitive samples, a refrigerated centrifuge may be more appropriate. iGene's cooling centrifuge range includes models with temperature control from approximately -20°C to +40°C, depending on the model.

Molecular Biology Lab Equipment Checklist

A molecular biology lab equipment plan should be built around the techniques the laboratory expects to perform. PCR-based workflows, nucleic acid preparation and electrophoresis can each introduce different equipment requirements.

PCR Machine

A PCR machine is required when the laboratory performs polymerase chain reaction workflows. Before selecting one, compare the number of wells, temperature control, programming options, throughput and compatibility with the laboratory's intended applications.

iGene's current Molecular Biology range includes a 96-well gradient thermal cycler, alongside other molecular biology instruments.

PCR Preparation Equipment

PCR work also requires appropriate preparation and contamination-control arrangements. Depending on the workflow, this can include a dedicated PCR workstation or cabinet, micropipettes, centrifugation equipment and suitable sample storage.

The aim is not simply to purchase a PCR machine. The surrounding workflow needs to support consistent sample preparation and handling.

Electrophoresis Equipment

When DNA, RNA or protein separation is part of the workflow, an electrophoresis system becomes an important consideration. iGene's vertical electrophoresis systems are designed for molecular biology and biochemistry applications and support techniques including SDS-PAGE, native PAGE and two-dimensional gel electrophoresis.

For laboratories planning gel-based analysis, also consider the appropriate power supply, gel documentation and imaging requirements.

Gel Documentation System

A gel documentation system allows researchers to capture and analyse images of electrophoresis gels. iGene's IG-618GD TOUCH includes a high-resolution camera and supports imaging of DNA, RNA and protein bands.

This type of equipment should be selected according to the gel formats, dyes, imaging requirements and documentation workflow used by the laboratory.

Microbiology Lab Setup vs Molecular Biology Lab Setup

The difference between a microbiology lab setup and a molecular biology lab setup is largely determined by the work performed.

Laboratory requirement	Microbiology	Molecular Biology
Controlled incubatio	High priority	Application dependent
Sterilisation	High priority	Important for relevant workflows
Biosafety cabinet	Workflow dependent	Workflow dependent
Centrifugation	Common	Common
PCR system	Not always required	Required for PCR workflows
Electrophoresis	Application dependent	Common for relevant analysis
Gel documentation	Application dependent	Required for gel imaging workflows
Cold storage	Often required	Often required
Spectrophotometry	Application dependent	Useful for nucleic acid/protein analysis

The distinction matters because buying every available instrument at the beginning can increase costs without improving the laboratory's actual workflow.

How to Plan Your Essential Laboratory Equipment

Before finalising an equipment list, answer these questions:

1. What tests or research activities will the laboratory perform?
2. How many samples will be processed each day or week?
3. What sample types and volumes will be handled?
4. Which instruments require temperature-controlled environments?
5. What biosafety and contamination-control measures are required?
6. How much laboratory space is available?
7. What utilities, power requirements and ventilation arrangements are needed?
8. Will the laboratory expand its testing or research activities later?

It is also worth checking service support, calibration requirements, spare parts availability, training and maintenance arrangements before placing an order. These factors can have a significant effect on the practical cost of operating laboratory equipment over time.

Choose Equipment Around Your Workflow

A new laboratory doesn't necessarily need the most sophisticated instrument available. A better approach is to identify the required workflow, establish capacity requirements and then compare suitable equipment specifications.

For example, a laboratory carrying out routine bacterial culture may place greater emphasis on incubation, sterilisation and safe sample handling. A molecular biology laboratory performing PCR and gel analysis may instead prioritise thermal cycling, centrifugation, electrophoresis and imaging.

iGene Labserve provides dedicated Microbiology and Molecular Biology equipment categories, allowing laboratories to review equipment according to their application requirements.

Planning a new laboratory in Delhi or upgrading an existing facility? Review the relevant equipment range and discuss your workflow, capacity and technical requirements with iGene Labserve before finalising your equipment list.

Conclusion

A successful laboratory begins with careful planning rather than simply purchasing a large number of instruments. Start by defining the work to be performed, estimate the expected workload, and consider space, safety, maintenance and future requirements before making purchasing decisions.

Choosing equipment according to actual working needs can help control unnecessary spending and create a more practical working environment. It also makes future expansion easier because new instruments can be added around an established workflow.

For laboratories being developed or upgraded in Delhi, taking time to discuss technical requirements with an experienced supplier can help ensure that each purchase is appropriate for the intended application.

FAQs

What equipment is needed for a new microbiology laboratory?

Common requirements can include an incubator, autoclave, appropriate biosafety equipment, centrifuge, storage equipment and other instruments based on the laboratory's specific culture and testing workflows.

What equipment is needed for a molecular biology laboratory?

Depending on the planned work, a molecular biology laboratory may require a PCR machine, centrifuge, PCR preparation equipment, electrophoresis system, gel documentation system and instruments for sample analysis and storage.

Is a PCR machine necessary for every molecular biology lab?

No. A PCR machine is necessary when PCR-based testing or research forms part of the laboratory's workflow. Laboratories performing other molecular techniques may require a different equipment combination.

How should I choose equipment for a new laboratory?

Start with the laboratory's intended applications, sample volume and workflow. Then compare equipment capacity, operating range, safety features, maintenance requirements, available space and future expansion needs.

Should a new lab buy all equipment at once?
