If you are a researcher working in the laboratory, you are sure to spot a high speed cooling centrifuge. Now, the device is extensively used for spinning samples and separating the components. With different models of centrifuges comprising highly functional rotors, spinning has been made easier and the turnaround time of sample preparation has reached at an all time high.
However, incorrect use of centrifuges poses safety risks and leads to ghastly accidents. Often, the rotor breaks apart the sample container and cause injuries to the operator. Apart from this, the leakage of liquids from the container may cause skin irritation or lead to buns when it comes into contact with the user. Research reveals that most of centrifuge accidents happen due to erroneous usage of the equipment.
Listed below are safety considerations one needs to follow within the laboratory settings when using the high speed cooling centrifuge device.
- Examining the equipment before use
The buckets and rotor of the device may corrode when they are constantly exposed to aggressive chemicals, moisture, and salts. If you overlook the corroded state of components, it may eventually lead to small holes on areas of cracks and scratches. Precisely, corrosion in any part of the device must be seriously dealt with or it may make the device unsafe for operation in the laboratory.
You need to check the entire unit before operation, especially the rotor and a trained technician needs to be deployed for this purpose. The rotors need to undergo proper inspection and checking due to repeated use.
- Use the centrifuge on a level surface
Experts recommend that a majority of lab devices need to be placed on a level surface. However, when it comes to a lab centrifuge, it is essential to place it on a flat surface. The reason is that an uneven surface may cause imbalance in the rotor. Centrifuge devices are designed on the principle that the direction of the gravity aligns with the rotor axis. Therefore, if you don’t place it on an even surface, it will fail to attain the balance even before the tubes are properly loaded. So, if you don’t want to throw the device out of balance, it may be potentially harmful for the device itself as well as the operators.
- Checking the speed and load tolerance
No matter which model of the high speed cooling centrifuge is being used, the manufacturer mentions the maximum load tolerance and the speed in the manual. If you disregard the capacity of the device and use higher load than what is recommended for the device, it may cause malfunction in the rotor. Even if the load is increased, the speed needs to remain intact or adjusted based on the instructions mentioned in the manual. In case, the material inside the container precipitates, one needs to consider the density gradient of the precipitate.
- Examine the tubes
The tubes used within the centrifuge device are rated based on chemical resistance, temperature, and speed. You need to find out whether they are compatible with the settings and application. They need to fit the settings of the high speed cooling centrifuge. Furthermore, the tubes need to undergo thorough checking as the slightest breakage error may cause them to break during operation. Make sure to check the O-rings, adapters, and caps to ensure that they are in proper condition. If you notice any imperfection in any part of the tube or the entire unit, consider it unsafe for operation.
Tips to follow before, during and after operation of the centrifuge
The high speed at which the centrifuge device operates increases the chances of injuries when it does not operate in the right manner. Moreover, it may also cause heat to build up in the sample and the system. Here is what you need to keep in mind before and during operation.
Before operation:
- Make sure the tubes and bowls are dry and the spindle is cleaned
- Use buckets and safety cups to stop the chances of spills and aerosol leakage
- The container and tubes must be balanced on the rotor
- Check the O-rings present on the rotor if you have proper training
- Follow the guidelines of the manufacturer for operation and maintenance
During operation:
- Check the maximum run speed of the rotor
- Examine the centrifuge to figure out if it operates properly
- Make sure the lid of the centrifuge device operates normally
- Open the lid of the device only when the rotor stops completely
A high speed cooling centrifuge used in the laboratory may lead to accidents when its components are not properly maintained or remain unchecked. To buy this device from a reputed manufacturer, connect with https://www.igenels.com/ known for manufacturing equipment in India.
