In the world of containment systems, maintaining sterility and minimizing contamination risks are top priorities. One essential component that plays a crucial role in achieving these goals is the VHP (Vaporized Hydrogen Peroxide) Passbox. This comprehensive guide will take you through everything you need to know about VHP Passboxes and how they can enhance the safety and efficiency of your containment system.

What is a VHP Passbox?

A VHP Passbox, also known as a Pass-through, is a specialized device designed to facilitate the transfer of materials or items between two areas with differing cleanliness levels while maintaining the highest level of sterility and cleanliness. It serves as a crucial barrier that prevents contaminants from entering a cleanroom or controlled environment.

Why Use a VHP Passbox in Your Containment System?

The use of a VHP Passbox is essential for several reasons:

• Contamination Control: VHP Passboxes ensure that only sterile or sanitized items enter controlled environments, reducing the risk of contamination.
• Efficiency: They streamline material transfer, saving time and minimizing disruptions in critical operations.
• Safety: VHP Passboxes protect operators from exposure to hazardous materials.

How Does a VHP Passbox Work?

VHP Passboxes operate by using vaporized hydrogen peroxide to decontaminate items being transferred. The process involves the following steps:

1. Items are placed in the source chamber.
2. The chamber is sealed.
3. Vaporized hydrogen peroxide is introduced, killing microorganisms.
4. After decontamination, items are moved to the receiving chamber.

Types of VHP Passboxes

There are several types of VHP Passboxes, each designed for specific applications. The most common types include:

Single Door VHP Passbox

A single-door VHP Passbox has one access door for transferring items. It is suitable for basic material transfer requirements.

Double Door VHP Passbox

A double-door VHP Passbox features two access doors, allowing for materials to be transferred in and out simultaneously, minimizing wait times.

Interlocked VHP Passbox

Interlocked VHP Passboxes are equipped with a system that ensures only one door can be open at a time, preventing cross-contamination.

Benefits of Using VHP Passboxes

Utilizing VHP Passboxes in your containment system comes with several advantages, including:

Contamination Control

VHP Passboxes maintain a sterile environment, reducing the risk of product contamination.
