The pass-through cabin with VHP (vaporized hydrogen peroxide) serves as a material air lock for the transfer of materials between rooms where there are different purity classes (usually B and C purity class). For the decontamination of instruments and materials, a decontamination cycle is employed with the help of hydrogen peroxide vapours. The VHP generator is a part of the decontamination pass-through cabin, thus they comprise a single device.
Pass-through cabins comply with the 4-leak tightness class pursuant to ISO 10648-2.
