In the realm of cleanrooms, ensuring the safe transfer of materials between areas while maintaining sterility is critical. Pass boxes play a vital role in this process. At YOUTH, we manufacture state-of-the-art cleanroom equipment designed to meet the high standards of various industries. This article compares the Vaporized Hydrogen Peroxide (VHP) pass box with the traditional pass box, highlighting their differences and advantages to help you make an informed choice.

What is a Pass Box?

A pass box is a device used to transfer materials between clean and non-clean areas within a cleanroom. There are primarily two types of pass boxes: traditional pass boxes and VHP pass boxes.

Traditional Pass Box

A traditional pass box, also known as a pass-through box, facilitates material transfers by minimizing the influx of contaminants. It usually operates on a simple mechanism involving UV lights or HEPA filters for basic sterilization.

VHP Pass Box

A VHP pass box, or VHP chamber, goes a step further by using Vaporized Hydrogen Peroxide (VHP) sterilization. This advanced system ensures a higher level of decontamination, making it ideal for sterile environments.

Key Differences Between VHP Pass Box and Traditional Pass Box

1. Sterilization Method:
   • Traditional Pass Box: Uses UV lights or HEPA filters to reduce contamination.
   • VHP Pass Box: Utilizes VHP sterilization and flash evaporation for a thorough decontamination process.
2. Sterilization Effectiveness:
   • Traditional Pass Box: Effective for basic sterilization needs but might not eliminate all microbial contaminants.
   • VHP Pass Box: Provides comprehensive sterilization, effectively neutralizing a wide range of microbial contaminants.
3. Process Duration:
   • Traditional Pass Box: Typically faster as it relies on simpler sterilization mechanisms.
   • VHP Pass Box: Takes slightly longer due to the VHP generation, distribution, contact time, and aeration steps involved.
4. Safety Features:
   • Traditional Pass Box: Basic safety features such as interlocking doors and UV lights.
   • VHP Pass Box: Equipped with advanced safety features like auto-pressure checking systems, leak and fault alarms to ensure safe operation.
5. Applications:
   • Traditional Pass Box: Suitable for industries with less stringent sterilization requirements.
   • VHP Pass Box: Ideal for pharmaceutical factories, biological laboratories, and other environments where thorough sterilization is essential.

Advantages of Using VHP Pass Box

1. High-Level Sterilization:
   The VHP pass box effectively destroys a wide variety of microorganisms, ensuring a contaminant-free transfer process.
2. Enhanced Safety:
   With features like auto-pressure checking systems and leak alarms, the VHP pass box offers enhanced safety compared to traditional pass boxes.
3. Versatility:
   The VHP pass box is versatile, making it suitable for industries with stringent cleanliness and sterilization requirements.
