Hydrogen peroxide pass box VHP

The VHP passbox is adopted for sterilization treatment of external surface of articles that cannot resist humidity or heat, and is applicable for sterile transfer of materials from the low-grade purification area to the high-grade one, pollution reduction of purification area. It mainly applies to fields like pharmaceutical, bio-experiment and food processing, etc. Transferable articles: material barrel, open-end vessel, operational tool, experimental apparatus and articles for sealed packaging, etc. Features: 1. High efficiency The process parameters may be flexibly adjusted pursuant to kinds and quantity of transferred articles. One sterile transfer may be completed within 1-2 hours. 2. Reliable sterilization effect The distinct “flash evaporation” technology is employed to instantly generate high concentration of hydrogen peroxide vapor (VHPS). A 10-6 sterility assurance level (bacillus stearothermophilus ATCC 7953) is guaranteed; The twin-channel detection with high-precision sensors and micro-metering systems are able to accurately control the hydrogen peroxide dosage and ensure the sterilization effect; All the air flowed into or out of inner room in the whole course of sterilization is filtered by H14-class high-efficiency filtration system, avoiding the secondary pollution. 3. High Security The integrated design of front & back door covers and cabinet guarantees complete isolation seal; The dual doors adopt interlocking, and the patented design of active expansion and sealing structures makes the sealing reliable;
