Biological Safety Cabinets

Class II Biological Safety Cabinet: As indicated in the previous section selecting a class II biological safety cabinet must take into consideration a considerable number of factors which include, among others, the work being done within the cabinet, the facility requirement based on bio safety levels, the location of the cabinet within the laboratory itself, the installation requirements of the Class II Biological Safety Cabinet and the exhaust/ supply system(s) to both the laboratory and the cabinet, whether or not the Class II Biological Safety Cabinet is to be vented.

Class III Biological Safety Cabinet : As indicated in the previous section selecting a Class III Biological Safety Cabinet must take into consideration a considerable number of factors which include, among others, the work being done within the cabinet, the facility requirement based on bio safety levels, the location of the cabinet within the laboratory itself, the installation requirements of the Class III Biological Safety Cabinet, and the exhaust/ supply system(s) to both the laboratory and the cabinet, whether or not the cabinet is to be vented.

The new recirculating range of vertical Biosafety Cabinets are available in three different modules.

Class I Biological Safety Cabinet: The class I biosafety cabinets provides personnel and environmental protection, but no product protection. It is similar in air movement to a chemical fume but usually has a limited fixed work access opening and the exhaust air must be HEPA filtered, to protect the environment. The class I biosafety cabinets is designed for general microbial research with low-and moderate-risk agents. In addition, the work zone, which type is much smaller than a chemical fume hood, is geared to working with biological whose process/ producers dictates the use of moderate amounts of volatile liquids, that are suitable for recirculating cabinets.

“Klonezone” class II A/B3 Bio- Safety Cabinets Class II Type A2 provide personnel, product, and environment protection. Bio- Safety Cabinets Class II Type A2 differ in the proportion  as 70% air is re-circulated within the cabinet through high efficiency particulate air (HEPA) filtration. Velocity of airflow to the work zone creates an ultra-clean environment for product protection, where the remaining exhaust air is discharged out. 

An internal blower draws sufficient room air through the front grille to maintain a minimum calculated or measured average inflow velocity of at least 75 lfpm at the face opening of the cabinet. The supply air flows through a HEPA filter and provides particulate-free air to the work surface. Laminar airflow reduces turbulence in the work zone and minimizes the potential for cross contamination. An unducted Bio- Safety Cabinets Class II Type A2 is not to be used for work involving volatile or toxic chemicals. The buildup chemical vapors in the cabinet (by re0circulated air) and in the laboratory (from exhaust air) could create health and safety hazards.
