Overview
The PEA VHP Sterile Transfer Pass-Through Chamber is an engineered solution for aseptic material transfer in high-containment life science, pharmaceutical, and biotechnology environments. It utilizes vaporized hydrogen peroxide (VHP®) technology — a validated low-temperature sterilization process based on controlled phase transition of liquid H₂O₂ into a true molecular vapor state. Unlike UV irradiation or formaldehyde fumigation, VHP achieves uniform surface coverage through gas-phase diffusion, enabling consistent microbial inactivation across complex geometries, shadowed areas, and porous packaging interfaces. The system operates at ambient pressure and temperatures below 35 °C, eliminating thermal stress on sensitive payloads including pre-sterilized vials, syringes, sensors, microfluidic devices, and electronic components. Its core architecture integrates flash-vaporization kinetics, real-time environmental parameter control (H₂O₂ concentration, RH, temperature, chamber pressure), and dynamic dehumidification to prevent condensation — ensuring both efficacy and material compatibility.
Key Features
- Third-generation German flash-vaporization module delivering fully gaseous H₂O₂ with <0.1 µm particle-free output — no aerosol, no droplets, no residue.
- Dual interlocked doors with pneumatic sealing and programmable access logic to enforce unidirectional workflow and eliminate cross-contamination risk.
- H14-grade HEPA filtration (ISO 14644-1 Class 5) integrated into laminar airflow system; automatic self-cleaning mode with timed recirculation.
- Real-time closed-loop monitoring of critical process parameters: H₂O₂ vapor concentration (ppm), relative humidity (%RH), temperature (°C), and absolute pressure (mbar).
- Pre-validated cycle protocols compliant with ISO 15883-1 and EN 17175; SAL ≤10⁻⁶ confirmed against Geobacillus stearothermophilus spores (ATCC 12980/7953) under worst-case load conditions.
- Fully traceable data acquisition with time-stamped audit trail, electronic signatures, and exportable CSV/CSV-UTF8 reports meeting FDA 21 CFR Part 11 requirements.
Sample Compatibility & Compliance
The chamber accommodates standard ISO trays, stainless-steel carriers, Tyvek-wrapped instruments, glass vials, polymer-based diagnostic kits, and electronics housings without degradation. VHP demonstrates broad-spectrum lethality against vegetative bacteria (e.g., Escherichia coli, Staphylococcus aureus), enveloped/non-enveloped viruses (e.g., MS2, Phi6), fungi (e.g., Aspergillus niger), and highly resistant bacterial endospores. Material compatibility testing per ISO 10993-5 confirms no corrosion, discoloration, or functional impairment on 316L stainless steel, anodized aluminum, silicone elastomers, polycarbonate, and PETG. Regulatory alignment includes EU GMP Annex 1 (2022), PIC/S TR 79, USP <1211>, and ISO 14644-1 Class 5 cleanroom integration standards.
Software & Data Management
The embedded control system runs on a deterministic real-time OS with password-protected user roles (Operator, Supervisor, Administrator). All process events — door cycles, sterilant injection, dwell phases, catalytic decomposition, filter status, alarm logs — are timestamped and stored locally with optional network backup. Audit trails include operator ID, action type, timestamp, and parameter values before/after change. Data exports support CSV and PDF formats with digital signature embedding. Optional IQ/OQ/PQ documentation packages are available, including protocol templates, test scripts, and summary reports aligned with ASTM E2503 and ISO 13408-1.
Applications
- Aseptic transfer of media plates, pipette tips, and cultureware between classified cleanrooms (Grade A/B to Grade C/D).
- Isolation barrier interface for isolator loading/unloading in sterile manufacturing suites.
- Biological safety level (BSL-2/3) lab material egress where chemical decontamination must precede physical exit.
- Cell therapy and mRNA vaccine production lines requiring rapid, residue-free sterilization of single-use bioreactor components.
- QC/QA laboratories performing sterility testing under ISO 11737-1 and Ph. Eur. 5.1.1.
FAQ
What is the maximum achievable log reduction with this VHP pass-through?
≥6-log reduction against Geobacillus stearothermophilus spores (ATCC 12980) under full-load validation conditions, satisfying SAL ≤10⁻⁶ per ISO 14644-1 and EU GMP Annex 1.
Does the system require external HVAC integration?
No — it operates as a standalone unit with internal recirculation and catalytic recombination; exhaust can be vented to general lab air or ducted externally per local safety regulations.
How is cycle reproducibility ensured across different operators?
All parameters are pre-programmed and locked; manual overrides require supervisor-level authentication and generate immediate audit entries. Each cycle generates a unique digital certificate.
Can chemical and biological indicators be used simultaneously during routine monitoring?
Yes — indicator strips (e.g., 3M™ Attest™ VHP) and biological indicators (BIs) containing ≥1 × 10⁶ CFU Geobacillus stearothermophilus spores are compatible and recommended for periodic performance qualification.
Is remote monitoring supported?
Optional Ethernet/IP or Modbus TCP interface enables integration with SCADA or MES systems; real-time status dashboards and email alerts for cycle completion or fault conditions are configurable.
