A VHP Pass Box (Vaporized Hydrogen Peroxide Pass Box) is a specialized cleanroom equipment designed to safely transfer materials between areas with different cleanliness levels while preventing cross-contamination. It utilizes vaporized hydrogen peroxide as a highly effective sterilizing agent, capable of eliminating bacteria, viruses, fungi, and spores from the surface of items placed inside the chamber.
The system operates through an automated sterilization cycle, including dehumidification, VHP injection, dwell time, and aeration. This ensures thorough decontamination without leaving harmful residues, making it ideal for use in pharmaceutical manufacturing, biotechnology labs, hospitals, and research facilities. The chamber is typically constructed from stainless steel with smooth internal surfaces to ensure easy cleaning and durability.
Equipped with interlocking doors, the VHP Pass Box prevents both doors from opening simultaneously, maintaining the integrity of controlled environments. Advanced models may include PLC control systems, touchscreen interfaces, and real-time monitoring for precise operation and data recording.
With its high sterilization efficiency, safety features, and compliance with cleanroom standards, the VHP Pass Box is an essential solution for maintaining strict hygiene and contamination control in critical environments.
