Biosafety Cabinets are specialized workstations widely used in clinical, pharmaceutical, life science and industrial laboratories where experiments highly needed contaminant free environment. Also known as biological safety cabinets and biohazard safety cabinets, these are made in three different class types such as Class 1, Class 2 and Class 3; in which Class 2 is widely used in microbiology laboratories because it provides protection to both product as well as personal. It is biosafety level factor which decides which BSC should be used in laboratory. These cabinets are considered safer than other clean benches because such BSCs effectively eliminate risks to operator / shottaff, samples and the environment from pathogenic biological agents (PBA) and microorganisms responsible for spreading airborne infection.
ere are three types of class 2 biosafety cabinets are made. It is the type of work which decides which class 2 BSC should be used in laboratory. Below is short description about all types: Type A2: recirculate approximately 70% air and 30% exhaust Type B1: recirculate approximately 30% air and 70% exhaust Type B2: Does not recirculate but exhaust 100% air
HEPA Filters: MINIPLATE with 99.99% efficiency for 0.3 microns with integral metal guards & Filter frame gaskets and manufactured in class 100 super clean air-conditioned environment for longer life. Air pressurization system: Statically and dynamically balanced, fitted with the special vibration-reducing system to suit low noise and vibrations. UV lamp: In the working zone (40 microwatts/ square cm at 254 mm or better) and placed so that the operator cannot see directly i.e. eyes will be always protected. Rehabeatable pre-filters should have an efficiency of more than 80%. Switches & Electrical sockets outlets for 15/5 amp. Should have Pressure Monitors digital Exhaust blower will be capable of 100% exhaust interconnected with supply air blower; the system will only start when the negative pressure is developed. Back holes will be there on vertical walls to provide more work area on the table. Provided with Switches & Electrical sockets outlets for 16 Amp. Suitable power supply 230 Volt AC
