Class II biological safety cabinets fall into four types (A1, A2, B1, B2), all of which protect the specimen, the user, and the environment from contamination. This is especially crucial for applications that require aseptic or particulate free conditions such as tissue culture experiments, and in toxicology work involving fumes and gases. All types of Class II biological safety cabinet have HEPA (high-efficiency particulate air) filters at their air supply and exhaust points.
For Type B1 and B2 Class II biological safety cabinets, more air is exhausted out of the cabinet. These cabinets are best used for applications that require larger quantities of volatile chemicals and/or radionuclides (although limit restrictions may still apply). Type B Class II biological safety cabinets must be connected to the building’s exhaust system to protect the user from vapors and gases.
Thick wooden board/Mild Steel Powder Coated/Stainless Steel 304 fabricated, , designed so as to throw-out all toxic/harmful vapors, thus protecting costly instruments and the person working in the lab. Working table Top is fitted with acid/alkali resistant tile. The front door moves vertically up and down with concealed counter balanced weight/by Hinges. The unit is fitted with fluorescent light and a gas cock for gas/air supply. The space under the work station can be provided with switches for exhaust system and fluorescent lights. Workable on 220 Volts AC supply.
This complete package unit is provided to give clean air to any laboratory. Useful where any hyper critical work has to be performed within minimum contamination as they assure 99.97% removal of airborne particles as 0-3 microns in the work area. The basic elements are pre-filters, heavy duty blower assembly; HEPA (high Efficiency particular Air) filter (Absolute filter) fresh air is drawn through the pre-filter and passes to absolute HEPA filter. Ultra clean air moves horizontally in Laminar flow bench cross the work area at a velocity of approximate 90; i 20 feet per minute.
