What Is A VHP Pass through Box?
Everything you need to know about VHP pass-through boxes
VHP pass-through box, also known as hydrogen peroxide pass-through sterilizer or vaporized hydrogen peroxide sterilizer, is a device that uses vaporized hydrogen peroxide to sterilize items in a closed environment. This device is widely used in the pharmaceutical, medical device, biotechnology and other industries to meet the sterilization requirements of products and equipment.
Here is some key information you need to know about the VHP pass-through box:
1. Working principle:
The VHP pass-through box works by injecting a certain amount of liquid hydrogen peroxide into the chamber, heating it to form vaporized hydrogen peroxide, and then distributing it evenly in the closed space. Hydrogen peroxide vapor can effectively kill bacteria, viruses, spores and other microorganisms on the surface of items. After sterilization, the residual hydrogen peroxide is decomposed and removed by catalyzer or vacuum extraction to ensure that the items are safe for use.
2. Advantages:
The VHP pass-through box or VHP pass-through chamber has many advantages compared with traditional sterilization methods. First, it has a strong sterilization ability, which can effectively kill various microorganisms, including spores that are difficult to kill. Second, the sterilization process is fast and efficient, usually taking only a few hours to complete. Additionally, the VHP pass-through box is suitable for sterilizing items that are sensitive to heat and moisture, and does not damage the material or function of the items. Finally, the residual hydrogen peroxide can be effectively removed, reducing the risk of chemical residue pollution.
3. Application scope:
The VHP pass-through box is suitable for sterilizing various items, including medical devices, surgical instruments, packaging materials, laboratory equipment, etc. It is widely used in hospitals, laboratories, pharmaceutical factories and other places that require high sterility.
4. Operation and maintenance:
Operating the VHP pass-through chamber requires strict compliance with the operating procedures to ensure the effectiveness and safety of sterilization. Before sterilization, it is necessary to clean and dry the items to be sterilized, and place them in the appropriate position in the sterilizer. During the sterilization process, it is necessary to monitor the temperature, humidity and hydrogen peroxide concentration to ensure that they are within the specified range. After sterilization, the residual hydrogen peroxide needs to be removed according to the specified procedure. In addition, regular maintenance and inspection of the equipment are also necessary to ensure its normal operation and prolong its service life.
In summary, the VHP pass-through box is an effective sterilization device that can meet the sterility requirements of various industries. Understanding its working principle, advantages, application scope and operation and maintenance requirements is helpful for correct and safe use of the device.
