VHP Pass Box: Vaporized Hydrogen Peroxide Sterile Transfer
The VHP pass box (vaporized hydrogen peroxide sterile pass box) is a sealed transfer device for biological decontamination of material surfaces, achieving a validated log-reduction before items enter aseptic areas. As a clean room pass box manufacturer, we build the cleanroom static pass box with integrated VHP generation and interlocked doors.
It is part of our complete material-transfer family with the static pass box, dynamic pass box and aluminum pass box.

Values shown are standard/representative configurations. Confirm final certified figures (decontamination cycle, leak test) against the project datasheet before specification — Wonclean issues a stamped datasheet with every quotation.
VHP Pass Box Construction
VHP-compatible sealing is the engineering secret. A 316L stainless interior with VHP-rated gaskets withstands hydrogen peroxide cycles without corrosion or residue, while dual-door interlocks and real-time H₂O₂ monitoring deliver validated, ≥ 6-log surface decontamination.
Why Choose Our VHP Pass Box
Validated ≥ 6-log kill
VHP cycles achieve ≥ 6-log biological reduction on surfaces without residue or corrosion.
Real-time monitoring
Live humidity and H₂O₂ concentration monitoring assures every decontamination cycle.
Secure interlocks
Dual mechanical and electronic interlocks maintain pressure cascade and isolation.
Data integrity
21 CFR Part 11 compliant cycle logging for audit-ready GMP documentation.
Corrosion-free 316L
Electropolished 316L interior resists VHP cycling for long service life.
System integration
Trolley-interface compatible and integrates with modular cleanroom systems and BMS.
