VHP Pass Box: The Pioneer of Innovation in Biological Decontamination Technology

In the modern medical, scientific and biopharmaceutical fields, the demand for a clean environment is becoming more and more stringent, especially the transfer of materials between different cleanliness areas, which can introduce deadly sources of contamination if not careful. To this end, VHP Pass Box has become a powerful tool to solve this problem with its unique low-temperature, atmospheric-pressure hydrogen peroxide sterilization technology. This article will discuss the technical characteristics, significant advantages and detailed technical parameters of  VHP Pass Box in depth, and show its excellent performance in the field of biological decontamination.

The guardian of biological decontamination

The core purpose of the VHP Pass Box, which is specially designed for biological decontamination of the outer surface of the material, is to block the migration of contaminants from the low cleanliness area to the high cleanliness area. With an external hydrogen peroxide generator (VHPS), the system performs decontamination tasks at low temperatures and atmospheric pressures, which is both environmentally friendly and efficient, and perfectly suits the stringent requirements of modern cleanrooms for material transfer.

Technical advantages: a comprehensive display of excellent performance

Innovations in sealing technology: VHP Pass Boxes are available in both gas-sealed and mechanically pressed versions. Among them, the inflatable sealing type adopts high-density EPDM sealing strip imported from Netherlands, combined with the hidden hinge design, to ensure excellent sealing performance and effectively prevent gas leakage during the sterilization process.

Efficient sterilization capacity: Compared with similar products on the market, the sterilization time of VHP Pass Box is shortened by 50%-70%, which significantly improves work efficiency. This is due to the optimized sterilization process and the efficient VHP generator design, which ensures that the material achieves the desired sterilization result in a short time.

Precise Control and Environmental Stability: The system has excellent containment and temperature control. Its tightness meets the test standard of pressure decay method, and the pressure change does not exceed ±250Pa within 20 minutes under ± 500Pa. At the same time, the temperature change during the sterilization process is controlled within ≤3°C to ensure the stability of the sterilization environment.

Intelligent operation and data management: The VHP Pass Box integrates the gravity sensor, touch screen control system and communication capability with the BMS system to realize the intelligent management of the sterilization process. Users can easily set and adjust sterilization parameters, and print online, remotely and store relevant data, which provides great convenience for production management.

Multiple safety guarantees: From the protective design of the door handle to the biosafety type closed valve configured inside, the VHP transfer window has achieved the ultimate in safety. Whether it is an inflatable or mechanically compressed door handle, it can effectively avoid injuries caused by misoperation. At the same time, the configuration of independent air duct system and bio-closed valve ensures that hydrogen peroxide will not leak into the external environment during the sterilization process.

Technical parameters: accurate interpretation of technical strength

Power supply: Single-phase AC power supply 220V/50Hz, suitable for a variety of use scenarios.

High efficiency level: H14 HEPA filters are used for both supply and exhaust air to ensure the high efficiency of air filtration.

Sterilization conditions: Sterilization tasks are performed in the temperature range of 18-35°C and pressure conditions of 0-100Pa, and the decontamination cycle time is less than 120 minutes.

Inflation performance: The inflation pressure reaches 1.5kg/cm², the inflation and deflation time is less than 5 seconds, and there is no explosion and air leakage after more than 10,000 repeated tests, demonstrating its excellent durability and stability.

Conclusion

With its excellent technical performance, efficient sterilization capability and intelligent operation experience, VHP Pass Box has set a new benchmark in the field of biological decontamination. It not only meets the strict requirements of modern cleanrooms for material transfer, but also provides strong support for the development of medical, scientific research and biopharmaceutical fields.
