VHP Pass Box: A Technological Pioneer for Efficient Sterilization

In modern medical, pharmaceutical, and scientific research fields, the maintenance of a sterile environment is the cornerstone of ensuring product quality and safety. VHP Pass Box, as an innovative technology in this field, has become the preferred solution for material transfer in aseptic environments due to its excellent control system, excellent performance and unique features.

Robust and durable structural body

The construction of the QUALIA VHP Pass Box is ingenious, and the main structure is made of durable stainless steel. Among them, the inner cavity is specially made of high-quality 316L stainless steel to ensure stronger corrosion resistance and cleaning convenience; The frame and appearance are made of 304 stainless steel, which is not only beautiful and generous, but also durable. In addition, the design of the inner cavity cleverly adopts the arc angle welding process, which is both beautiful and easy to clean. In terms of surface treatment, theQUALIA VHP Pass Box  adopts a high-precision polishing degree of Ra≤0.6um, which makes the surface smoother, effectively reduces the adhesion of microorganisms, and further improves the sterilization effect. As for the VHP generator, Qualia uses an advanced flash ignition principle dry VHP generator. The generator and the Pass Box  adopt a unified integrated control mode, which makes the VHP generation concentration, cavity body temperature, humidity and saturation control more refined and stable. In terms of pneumatic sealing system, the QUALIA VHP Pass Box adopts an advanced compressed air power system. Among them, the control of the inflatable seal and the pneumatic valve share a compressed air line, and are equipped with a pressure reducing valve and a solenoid valve to ensure fine and efficient control. The other compressed air is controlled by a separate pressure reducing valve and a solenoid valve, which is specially designed for fine adjustment of the saturation of the chamber.

Control system

At the heart of theVHP Pass Box is its efficient control system. The control system ofQUALIA VHP Pass Box adopts advanced PLC and HMI control methods, and is equipped with standard modular control board to ensure the stability and reliability of the system. This design has been rigorously verified and widely practiced, providing a solid guarantee for the stable operation of the equipment. When it comes to purification and filtration systems, the QUALIA VHP Pass Box also performs well. The supply and exhaust air of the chamber are equipped with high-efficiency H14 filters to ensure the purity of air quality. At the same time, the process pipeline and cavity itself also adopt a purification design, and cooperate with the high-efficiency filtration system to achieve a class A purification effect. The equipment also reserves a detection port to facilitate online test and verification of purification conditions to ensure the reliability of purification effect. When it comes to electrical systems, the Quali VHP transfer window also follows strict safety and protection regulations. The design of the electrical cabinet is reasonable, the layout of the electrical circuit is orderly, the strong current and weak current are clearly marked, and it meets the CE and EN standards. In order to ensure the safety of personnel and products, the equipment is designed with safety precautions in mind. The strong current safety protection mechanism is adopted to ensure that the operator cannot contact the strong current part. At the same time, emergency stop buttons are set on both sides of the device to quickly cut off the power supply in case of emergency. High-temperature components are also clearly marked for high temperature to alert operators to safety. In addition, the cavity also adopts an electromagnetic interlock device, which effectively avoids the contamination of the product and the clean room. When the equipment is in an abnormal state, it will also send out an audible and visual alarm signal to remind the operator to deal with it in time to avoid the occurrence of safety incidents.

Wide range of applications

It is worth mentioning that the applicability of VHP Pass Box is very wide. It is not only suitable for the sterilization of laboratory utensils, reagents, sterile tables and other items, but also widely used in the sterilization of surgical instruments, ward supplies and other items in medical institutions. In addition, in pharmaceutical companies, VHP Pass Boxes are also commonly used for the sterilization of raw materials, packaging materials and other items to ensure the aseptic quality and safety of products.

Conclusion

With its efficient control system, excellent performance and unique characteristics, VHP Pass Box plays an irreplaceable role in the field of material transfer in aseptic environment. With the continuous progress of science and technology and the continuous improvement of the requirements of aseptic environment, VHP Pass Box will continue to play its unique advantages and contribute more to the development of medical, pharmaceutical and scientific research fields.
