What is the Sterilization or Decontamination Process for the Pass Through Box?

The sterilization or decontamination process for a Pass Through Box is crucial to maintaining a controlled and clean environment during the transfer of materials between cleanrooms or controlled areas. The specific sterilization or decontamination methods can vary based on the design and features of the Pass Through Box. Here are common sterilization and decontamination processes for Pass Through Boxes:
Surface Disinfection:
Pass Through Boxes are often designed with surfaces that can be easily disinfected. Common disinfectants such as isopropyl alcohol or hydrogen peroxide may be used for routine surface cleaning to eliminate contaminants.
UV-C Sterilization:
Some Pass Through Boxes are equipped with ultraviolet (UV-C) light sterilization systems. UV-C light is effective at killing or inactivating microorganisms, including bacteria and viruses. The UV-C system may be activated after material transfer to sterilize the internal surfaces.

Hydrogen Peroxide Vapor Sterilization:
In certain applications, Pass Through Boxes may undergo hydrogen peroxide vapor sterilization. This method involves introducing a vaporized form of hydrogen peroxide into the chamber to disinfect surfaces and kill microorganisms.
Ozone Sterilization:
Ozone can be used for sterilization purposes in some Pass Through Boxes. Ozone has strong oxidative properties and is effective at eliminating a wide range of microorganisms. After material transfer, ozone may be introduced to sterilize the internal surfaces.
Autoclaving:
Pass Through Boxes with components that can withstand high temperatures and pressure may be autoclaved. Autoclaving is a common method of sterilization that uses steam under pressure
to eliminate microorganisms.
Disinfection Chambers:
Some Pass Through Boxes have integrated disinfection chambers. In this design, the Pass Through Box is equipped with a separate chamber that can be filled with a disinfectant or sterilizing agent. Materials are exposed to the agent before entering the cleanroom.
Gaseous Sterilization:
Gaseous sterilization methods, such as ethylene oxide (EtO) sterilization, may be suitable for Pass Through Boxes. Ethylene oxide is a gas that can penetrate various materials to sterilize them effectively.
Differential Pressure Monitoring:
Pass Through Boxes may feature differential pressure monitoring to maintain a controlled pressure environment. This helps prevent the ingress of contaminants, and the controlled pressure differential can be part of the decontamination strategy.
