According to the difference in the level of biological security, Biosafety Cabinet can be divided into three levels, two and three. Level 1 Biosafety Cabinet protect workers and the environment without protecting the sample. Biological safety cabinet airflow principle and laboratory fume hoods are basically the same, the difference is that the exhaust port is equipped with HEPA filter, the external exhaust filter and thus prevent the spread of microbial aerosol pollution. A biological safety cabinet itself without fan, relying on external ventilation ducts in the fan-driven air, because the cabinet can not protect the product, is currently less used.
Biosafety cabinets are biosafety protection isolators for biosafety laboratories and other laboratories. Can prevent harmful aerosols, aerosol diffusion; the operator, the sample and the sample cross-infection and the environment to provide security protection.
Biological safety cabinet Functional Description:
1, the product meets the NSF-49 standard on the CLASS Ⅱ Type A2 type requirements, air flow 30% emissions, 70% recycling. Vertical laminar flow negative pressure model.
2, LCD full Chinese man-machine dialogue, and accompanied by the relevant operating procedures prompted friendly interface, with filters and fans, lamp operating time statistics (or LED display operating parameters), touch key operation, microcomputer automatic control and air volume automatic compensation control , Full monitoring.
3, the operating cavity for the SUS304 all stainless steel forming, rounded structure,Biosafety Cabinet the activities of the table for easy cleaning and maintenance. 4, 2 * 40W lighting, Shu eyes design.
5, 1 * 30W UV sterilization, etc., to eliminate hidden dangers of microbial contamination.
6, equipped with security alarm system. 1. Filter block alarm 2. Blower overload alarm 3. Work window open limit alarm
7, the work area power output socket WCD, with waterproof cover and overload protection.
8, the use of high quality and high efficiency filter (HEPA), for more than 0.3μm particle blocking rate of 99.995%. Ultra-efficient filter (ULPA) (US HV filter membrane),Biosafety Cabinet the greater than 0.12μm particle blocking efficiency of 99.999%. 9, integrated sliding safety glass sliding door any positioning, easy to operate, and can be completely closed for sterilization.
10, the operating surface of the face and tilt 10 ° two styles,Biosafety Cabinet more ergonomic theory, user-friendly design for the user to choose.
11, biological safety cabinet bracket-type safety cabinet, bracket and the upper box can be separated, easy to carry and in place.
