What is a laminar airflow cabinet?
A
laminar airflow cabinet is a closed cabinet fitted with HEPA
(High-Efficiency Particulate Air) filter airflow system. The air flows
with a steady, uniform velocity of 0.3 m/s to 0.5 m/s. The
inwards flow of air through one or more HEPA filters creates a
particulate-free environment for carrying out specialised work. The
instrument protects the product from contaminants. Laminar airflow hoods
work with biological samples, sensitive materials, and semiconductors.
The Laminar flow hood has undergone a massive change since it was first
developed in the 1960s. Keeping the air safety in check, in laboratory
enclosure, this product is still quite relevant in all scientific
research. The performance varies with the work performed and the
principle is guided by unidirectional airflow and maintenance of
sterility preventing cross-contamination and reducing turbulence. The
efficiency of this filter in removing 99.9998% of all particles >0.12
μm in size and streamlining the airflow both vertically and
horizontally across the work surface.
Where can laminar airflow be used?
Medical labs: Sterile
environment is required in labs to prevent airborne contaminants
affecting samples in experiments. The UV lamp sterilizes the workplace
and inhibits contaminants such as bacteria and viruses from travelling.
When working on the laminar airflow, scientists and researchers switch
off the UV light to protect the operator from exposure.
Tissue Culture: For bio-scientists, tissue culture is an integral part of cell study in a multicellular organism. Tissues are manipulated and analysed in a well-defined atmosphere. The contamination-free environment makes it ideal for cultures to be tested and analysed.
Food processing: Useful in the packaging of small-scale food, laminar airflow cabinets are used in packaging and processing by food formulation and testing labs.
Pharmaceutical production: Before
a drug enters the market, enormous research is undertaken by scientists
to develop it. For the process of formulating the drug, scientists need
to take help from the laminar airflow benches where they do sample
study and carry out experiments.
Medical equipment manufacture: When
medical equipment is manufactured it is important to maintain sterility
for ensuring that the equipment is free from contamination. Laminar airflow is used during the manufacturing process.
Assembling Electronic parts: The
delicate microchip is extremely sensitive to atmospheric contamination.
A laminar airflow provides the right resistance from any form of
contagion. These chips are tested and assembled in the laminar airflow
cabinet.
Protection to movie lenses: Dust that easily attaches to lenses creates marks on the film when in use and can spoil the film quality. Modern movie projections are assembled in laminar airflow technology to keep dust away from modern movie projections.
Data Rescue: Laminar airflow benches are used for data retrieval from hard drives, flash drives and other digital devices.
What Precautions Must you take before using the Laminar airflow benches?
- Considering the following while using the Laminar airflow benches will keep the system and the user safe.
- Sterilize the Laminar airflow benches with UV light pre-and-post-operation.
- Remember to switch off the UV light and airflow when working on the Laminar airflow benches.
- Wear lab coat and long gloves during operation.
- Sterilize thoroughly the working bench, glass shield, and other components present inside the cabinet after work is over.
