Brief introduction: BSC - 1200 Ⅱ A2 type 30% outside the biological safety cabinet (hereinafter referred to as the safe cabinet) is a kind of local work environment clean air purification equipment, and the workspace has polluted air through a special filter channel artificially controlling emissions, avoid the harm to people and environment, the special clean bench is a safe means of microorganisms. It can also be applied to biological laboratory, medical and health, biological pharmacy and other related industries, and has good effects on improving technological conditions and protecting the health of operators. Technical features: 1. Second-generation control interface, easy to operate; 2. Painting technology of steel plate, all stainless steel materials are available; 3. Move the threshold alarm to remind the operator at any time; 4. Equipped with special waterproof socket and sewage discharge interface, providing great convenience for operators; 5. Convex wind wall, which forms a complete isolation between working area and operators; 6. The exhaust air has a special high efficiency filter to ensure that the air discharged meets the national health requirements; 7. Adopt positive pressure pollution area surrounded by negative pressure area; 8. 30% external ventilation and 70% internal circulation. Performance parameters: Material: exterior steel plate, interior stainless steel (all stainless steel is optional) Cleanliness: CLASS A The wind speed: 0.25 ~ 0.5 m/s Number of colonies: 0.5b/dish • time (for the culture of 90mm with 209E) Inlet velocity in front: greater than 0.5 m/s Air tightness of box: pressure drop by 10% (30min at 500pa) Vibration semi peak value: less than or equal to 5 x m(800mm according to ground) Working area size: 1200*615*660mm Appearance size: 1400*800*2160mm
