Biosafety Cabinet Level 2 Type A2

In order to meet varying research and clinical needs biosafety cabinets are designed mostly in 3 types i e.

Biosafety cabinet level 2 type a2.

Labgard nu 437s class ii type a2 biosafety cabinet. Regardless of type each cabinet provides the same level of protection. Types of class 2 biosafety cabinet. What class ii type a2 and type b2 bscs provide use hepa filter technology contain and protect the user from biological agents protect the environment protect the samples inside the work area provide unidirectional laminar downflow can be used for biosafety levels 1 2 3 thimble or direct ducted a2 and b2 can be used with volatile toxic.

Purifier logic class ii type a2 biosafety cabinets bscs provide personnel product and environmental protection from hazardous particulates such as agents that require biosafety level 1 2 or 3 containment. Hazardous particulates such as microorganisms that require biosafety level 1 2 or 3 containments are protected from by using a class ii a2 type biological safety cabinet. Class ii type a2 biosafety cabinets. Also for use with antineoplastic drugs genetic material carcinogens allergens and other substances that generate hazardous airborne particulates.

They may exhaust hepa filtered air back into the lab or may be exhaust outside using a canopy. The labgard es nu 437s class ii biosafety cabinet monitors plenum pressure through microprocessor controls. Class ii type a a1 a2 biological safety cabinets the class ii type a biological safety cabinet is the most common class ii cabinet. A2 b1 or b2 provide the same level of product and personnel protection from a biological point of view.

These energy efficient cabinets provide both personal and product protection from biological hazards and contamination and can be connected to external exhaust to provide protection for volatile toxic chemicals used in the cabinet. Like class i cabinets class ii cabinets are safe for work using agents requiring biosafety level 1 2 or 3 containment. A biosafety cabinet bsc also called a biological safety cabinet or microbiological safety cabinet is an enclosed ventilated laboratory workspace for safely working with materials contaminated with or potentially contaminated with pathogens requiring a defined biosafety level several different types of bsc exist differentiated by the degree of biocontainment required. Type a2 type b1 and type b2.

A class ii type a1 cabinet must maintain a minimum average inflow velocity of 75 fpm through the sash opening. All of nuaire s class ii bscs regardless of type i e. It has a common plenum from which 30 of air is exhausted and 70 re circulated to the work area as the downflow. The nsf international listing program for compliance standard nsf ansi 49 has subjected each type to the exact same minimum testing procedures and exactly the same pass fail.

Class ii type a2 biosafety cabinet is produced in conformity with the requirements of european standard en 12469 2000.
