VHP PASS BOX
The low-temperature vaporized hydrogen peroxide sterilizer (VHPS) uses the superior sporicidal action of H₂O₂ vapor at ambient temperature compared with its liquid form. Hydroxyl radicals attack cellular components, including lipids, proteins and DNA, to achieve complete sterilization.
STANDARD CONFIGURATION
• Siemens PLC and touchscreen
• Chamber differential pressure, temperature, humidity and concentration monitoring
• Inlet and exhaust differential pressure monitoring
• EC fan
• Load cell
• Peristaltic pump
• Integrated VHP generator
• Inflatable sealing gasket
TECHNICAL SPECIFICATIONS
• Cleanliness: Grade A
• Filtration: H14 (99.995%)
• Cycle time: ≤ 90 min
• Sterilant concentration: 200–700 ppm
• Residual concentration: ≤ 1 ppm
• Leak rate: Q/V ≤ 0.5%
• Sterility assurance: SAL ≤ 10⁻⁶
• Disinfection efficacy: ≥ 99%
