San Francisco Biosafety Cabinet Testing Includes

Inflow Velocity

Inflow velocity measures the air entering the cabinet and is conducted to check the cabinet's ability to create a protective airflow that will prevent hazardous vapors and substances from escaping in to the work area.  GL Technologies will use specialized instruments such as an "anemometer" to measure the inflow velocity at different locations within the cabinet.  This will test that the air is being drawn in to the cabinet properly to maintain a safe working environment for researchers and minimizing the risks for all lab workers.  

Downflow Velocity

Downflow velocity is the speed at which air is directed downward from the cabinet's HEPA filters to create a controlled airflow area.  Our team will measure the downflow velocity to determine the cabinet's ability to provide a sterile work environment to protect both researchers and the samples being tested.  Our goal will be to verify the biosafety cabinet is working as needed and if we find any issues they will be identified and fixed so it works as required.  

Non-Viable Airborne Particle Concentration

Non-viable particles are particles that don't contain living organisms, such as dust.  We will measure the concentration of these types of particles to determine how the cabinet's air filtration system is working and its ability to keep a clean environment.  This testing will make sure the biosafety cabinet meets the manufacturers' specs and general regulatory standards to stop non-viable particles.
