1. Product overvie
1.1 Basic product information
1.1.1 BSC-1304 Ⅱ B2 Biological safety Cabinet (hereinafter referred to as the cabinet) has been
designed and manufactured conforming with the standard YY0569-2011 Class Ⅱ Biological
Safety Cabinets, A2 type.
1.1.2 The front access opening, through where the operator works in the cabinet. The room air flows
into the front access opening, forms an air barrier to prevent aerosols escaping from the
cabinet’s working area, so protects operator. ULPA-filtered air flows downward through the
working area, providing product and cross contamination protection. ULPA-filtered air exhausts
out of the cabinet, which protects the environment.
1.1.3 The cabinet may be the best physical protective barrier to protect personnel, product and the
environment. The operator must be well trained and familiar with the safety operation rules
before use the cabinet. Misuse will cause immediate harm to personnel, product and the
environment.
Reminder: Must be operated by trained personnel.
Warning: B2 type cabinet can be used for microbiological experiment hich uses
volatile toxic chemicals or radionuclide as adjuvant.
Reminder: Misuse ill cause immediate harm to personnel, product and the
environment.
