Biosafety Airtight Stainless Steel Pass Box in Biosafety Lab

Biosafety airtight pass box is mainly used in rooms with airtight requirements in high-level biosafety laboratories (BSL-3, BSL-4, ABSL-3, ABSL-4), which can solve the airtight problem of logistics channels. The double doors of the airtight transfer window adopt mechanical and inflatable double sealing methods to ensure the air tightness of the logistics channel, that is, the high elastic sealing ring and inflatable sealing ring are installed on the door panel of the transfer window, and a double sealing belt is formed between the door and the door frame through the pressing mechanism. As an item transfer equipment, the pass box is mainly used for the transfer of small items between the low pollution probability area and the high pollution probability area. The double door adopts an interlock device to avoid direct communication between different areas; At the same time, the VHP disinfection interface is set up, which can be used to connect the VHP disinfection equipment to disinfect the items in the pass box, which can effectively reduce the contamination in the transfer process.

Performance index

1. Mechanical devices and rubber components temperature environment adaptability: -40℃~+50℃;

2. Structural pressure resistance: ≥2500Pa;

3. Air tightness: under the pressure of -500Pa, the inner cavity of the transfer window is kept airtight, and the leakage rate is less than <0.5%vol/h;

4. Self-cleaning ability: After opening the self-circulating fan, the cleanliness in the transfer window can reach the A-level purification requirements;

5. Disinfection method: VHP disinfection can be carried out on the internal space of the pass box and internal items, and the disinfection effect can be verified;

6. Corrosion resistance: made of high-quality stainless steel, resistant to disinfectants, cleaning agents and acid, alkali and other chemical reagents.
