Haier Biomedical HGYX-Y100 Vaporized Hydrogen Peroxide (VHP®) Sterilizer

Overview

The Haier Biomedical HGYX-Y100 is a compact, self-contained vaporized hydrogen peroxide (VHP®) sterilizer engineered for rapid, residue-free decontamination of enclosed laboratory environments and critical containment equipment. It operates on the principle of controlled phase transition: liquid pharmaceutical-grade hydrogen peroxide (typically 30–35% w/w) is precisely metered, heated to its vaporization point (typically 100–130 °C), and delivered as a homogeneous, low-concentration (<1000 ppm) vapor-phase biocide into target enclosures. The VHP® penetrates porous surfaces, passes through HEPA filters without degradation, and condenses microscopically onto all exposed surfaces—initiating oxidative damage to microbial proteins, lipids, and nucleic acids. Unlike ethylene oxide or formaldehyde, VHP® decomposes spontaneously into water vapor and oxygen, eliminating toxic residuals and enabling same-day re-entry post-aeration (typically 30–60 min). The HGYX-Y100 is not a standalone chamber sterilizer but a mobile generator designed for integration with biosafety cabinets (Class II/III), CO₂ incubators, ultra-low temperature freezers (-80 °C), cold rooms, isolators, and small-volume BSL-2/BSL-3 laboratory spaces (≤100 L effective volume).

Key Features

• Controlled VHP® Generation: Dual-stage thermal vaporization system ensures stable output across the full 1–10 mL/min delivery range, with peak capacity up to 500 mL/min for accelerated cycle times.
• DNV Standard Quick-Connect Interface: Enables tool-free, leak-tight coupling to ducting or equipment ports compliant with DIN 12957 / DNV-RP-B401 specifications.
• One-Touch Sterilization Protocol: Pre-programmed cycles (including conditioning, injection, dwell, and aeration phases) are initiated via front-panel interface; all parameters logged with timestamp and operator ID.
• Pre-Cycle Safety Interlock: Integrated audible and visual alert system confirms door seal integrity, ambient humidity ≤60% RH, and target enclosure readiness prior to vapor release.
• Corrosion-Resistant Architecture: Enclosure and fluid path components utilize 316L stainless steel and PTFE-lined valves; exterior finished with electrostatic epoxy powder coating (C3 corrosion class per ISO 12944).
• Portability & Ergonomics: Weighing only 12 kg net with integrated carrying handles and non-marking casters, the unit meets IEC 61000-3-2 harmonic emission standards for lab-grade mobility.

Sample Compatibility & Compliance

The HGYX-Y100 is validated for use with standard laboratory materials including stainless steel (304/316), borosilicate glass, polycarbonate, PTFE, silicone elastomers, and epoxy-coated surfaces. It is incompatible with unprotected copper, brass, zinc-plated metals, and alkaline-sensitive polymers (e.g., polyacetals). While not certified to EN 17177 (VHP® generator standard) or ISO 14937 (sterilization process validation), the device supports user-led IQ/OQ/PQ execution in accordance with ISO 13485:2016 and FDA 21 CFR Part 820. Its operational envelope aligns with ISO 14644-1 Class 5 cleanroom requirements when deployed within sealed enclosures. Cycle data—including real-time H₂O₂ concentration (via integrated electrochemical sensor), temperature, relative humidity, and exposure duration—is recorded for audit-ready traceability under GLP/GMP frameworks.

Software & Data Management

The HGYX-Y100 embeds a non-volatile memory module retaining ≥1,000 complete cycle logs, each containing start/stop timestamps, operator ID, selected program ID, measured vapor concentration profile, and pass/fail status per ISO 14644-3 Annex B criteria. Data export is supported via USB 2.0 (FAT32 formatted drive) in CSV format, compatible with LIMS platforms and electronic lab notebooks (ELN). No cloud connectivity or remote access functionality is implemented—ensuring full data sovereignty and compliance with institutional cybersecurity policies. Audit trail functionality satisfies FDA 21 CFR Part 11 requirements for electronic records when paired with institutional SOPs governing user authentication and log review.

Applications

• Decontamination of Class II A2/B2 biosafety cabinets between user shifts or after aerosol-generating procedures
• Terminal sterilization of CO₂ incubators prior to cell line transfer or maintenance shutdown
• Reactivation of ultra-low temperature freezers following defrost cycles or contamination incidents
• Periodic bio-decontamination of glovebox interiors and transfer locks in BSL-2 laboratories
• Emergency response for localized spills involving select Category A/B agents (per institutional EH&S authorization)
• Validation support for ISO 14644-3 particle challenge testing in mini-environments

FAQ

What hydrogen peroxide concentration is required for optimal performance?
Pharmaceutical-grade 30–35% w/w aqueous hydrogen peroxide is recommended; higher concentrations (>40%) risk thermal decomposition and condensate formation.
Can the HGYX-Y100 be used inside a fume hood?
No—operation requires a sealed, static environment. Fume hoods actively exhaust vapor, preventing required concentration buildup and invalidating cycle efficacy.
Is third-party validation support available?
Haier Biomedical provides protocol templates and material compatibility matrices; full validation must be performed by the end-user’s qualified microbiology or sterilization team per ISO 14937.
Does the unit include an integrated hydrogen peroxide sensor?
Yes—a calibrated electrochemical sensor monitors real-time vapor concentration (0–2000 ppm range) with ±5% accuracy and logs data at 10-second intervals.
What maintenance is required?
Quarterly inspection of vaporization nozzle, annual calibration of H₂O₂ sensor, and replacement of inlet filter every 200 hours of operation—documented in the included maintenance logbook.
