Enviro Certification Services performs all primary and secondary tests as detailed by ANSI/NSF Standard Number 49 and the equipment manufacturer on all Class II biological safety cabinets and laminar flow benches. BSC testing and certification services are performed in accordance with up to date Standard Operating Procedures.
All biosafety cabinets must have an initial certification and must be recertified at least annually to ensure proper safe operation. As per current standards the operational integrity of the BSC must be verified and certified before being released into service or after being repaired or relocated. All new biosafety cabinets should be tested to ensure that no damage has occurred during shipping and it has been integrated properly into your facility design. Regular maintenance and certification of your biosafety cabinet is vital to the safety of your laboratory personnel and the validity of your research.
Our services are not just limited to routine maintenance but also full repairs to any component including decontamination and HEPA filter replacement. For each unit tested, full report documentation is provided detailing the test results.
For all annual biosafety cabinet certifications a field technician will proficiently perform the following Primary tests as applicable on each unit:
We provide complete service and repair for all makes and models.
Biological Safety Cabinets in Research
BSCs are designed to protect laboratory personnel and the environment from exposure to biohazards through the combined use of laminar flow and High Efficiency Particulate Air (HEPA) filters. HEPA filters trap the Most Penetrating Particle Sizes (MPPS) of 0.3 μm with an efficiency of at least 99.97%. Larger and smaller particles are captured with greater efficiency. Thus, bacteria, spores, and viruses are removed from the air by HEPA filters.
Many BSCs are equipped with multiple alarm systems that warn users if the airflow in the cabinet is compromised. There are 2 types of alarms that you could expect to find on a BSC. The first, which is required on ALL BSCs is the sash alarm, which should sound when the sash is raised approximately one inch over the intended usage mark. The second type of alarm is an airflow alarm and is usually dependent on the type of cabinet you are using and its configuration. All type B2 and A cabinets equipped with an externally vented canopy are required to have a compliant alarm. If your BSCs alarm is sounding you should not work in the enclosure, instead consult a qualified technician to inspect your BSC.
