What are the suitable applications for Class II Biosafety Cabinet?
Handling of low to moderate risk biological agents -Applicable for handling pathogens under Risk Groups 1,2, and 3
What type of protection does Class II BSC offer?
Class II Biosafety Cabinets are open-fronted which protect the laboratory workers and the environment from harmful biological agents. Class II BSCs also prevent biological materials (i.e cell cultures, microbiological stocks) inside it from being contaminated.
Can I handle body fluids such as blood, serum, and urine samples in a class II BSC?
Yes, Class II BSC is the most common type used for handling blood, serum, and urine samples. The Class II BSC provides a sterile environment for the samples and reduces the risk of cross-contamination while protecting the operators from the biohazards.
Can we use chemicals in a Class II BSC?
Some microbiological processes require small amounts of chemicals. This type of handling is allowed as biological safety cabinets may be upgraded to have a thimble ducting or carbon filter to accommodate small volumes of chemicals. However, a high concentration of corrosive acids is not allowed as it may damage the ULPA filters and cause corrosion.
Can a microscope be used in a Class II Biological Safety Cabinet?
Yes. For additional convenience, Class II BSCs can be customized to have a microscope pouch. Please contact your local Lorderan representative for more information.
What is the shelf life of HEPA or ULPA filters?
The estimated shelf life of HEPA or ULPA filters is up to 10 years when stored properly.
How to store HEPA or ULPA filters properly?
Filters should be kept in their original packaging and should not be exposed to dampness, excessive heat, cold or rapidly changing temperatures. These filters can tolerate up to 95% humidity; anything higher can cause the filter media to block and fail.
