iOTA SERIES                                             BIO-SAFETY CABINETS

"iOTA Series" Biosafety Cabinet is mainly used for handling pathogenic biological samples or for applications that require a sterile work zone. A biological safety cabinet creates inflow and down flow of air that provides operator protection.

iOTA CLASS II
The Class II Biosafety Cabinet is mainly used for handling pathogenic biological samples or for applications that require a sterile work zone. A biological safety cabinet is designed to have: an inflow for protecting the operator, an ULPA/HEPA-filtered down flow which creates an ISO Class 3 work surface that prevents cross contamination for protecting the sample, and an ULPA/HEPA-filtered exhaust for protecting the environment. For Type A1 and A2 Class II biological safety cabinets (A2 has a higher air velocity for greater protection), 70% of the airflow is re-circulated within the cabinet while 30% of the air is exhausted (usually through the top). These cabinets do not protect against vapors and gases and, therefore, are best used for applications requiring sterile conditions without the need to work with volatile chemicals. However, when a Type A2 Class II biological safety cabinet is connected to a building’s exhaust system (through an optional canopy), trace amounts of volatile chemicals and radionuclides may be used.
