Overview
The Taiwan-made Glovebox with Integrated Gas Purification and Regeneration System is an engineered inert-atmosphere containment platform designed for rigorous scientific and industrial applications requiring strict control of moisture, oxygen, and particulate contamination. Built upon a robust SUS304 stainless steel chassis with electropolished interior surfaces and powder-coated exterior, this glovebox operates as a sealed, positive-pressure environment maintained via closed-loop gas recirculation through high-efficiency purification modules. Its core functionality relies on catalytic deoxygenation and desiccant-based dehydration—enabled by heated, regenerable stainless-steel purifiers—to achieve and sustain ultra-low residual levels of H₂O (<1 ppm(v)) and O₂ (<1 ppm(v)). The system supports nitrogen, argon, or helium as the primary working gas and integrates real-time trace-level monitoring via dual electrochemical sensors (moisture and oxygen), enabling continuous validation of atmospheric integrity. Designed for compliance-driven workflows, it accommodates GLP/GMP-aligned documentation requirements through PLC-based audit trails, programmable regeneration logs, and deterministic pressure/vacuum sequencing.
Key Features
- PLC-controlled automation with 5.7-inch HMI interface supporting multilingual operation (English firmware available), offering fully programmable purge, regeneration, and pressure management routines.
- Three-mode regeneration control (fully automatic, semi-automatic, manual) with memory retention of regeneration timestamps and cycle history displayed directly on the HMI screen.
- Dual antechambers—large (Ø390 × 600 mm) and small (Ø150 × 300 mm)—each equipped with KF-25/KF-40 vacuum components, oil-damped gauges, and PLC-synchronized vacuum/pressure equalization to minimize cross-contamination during sample transfer.
- High-integrity sealing architecture: chamber leak rate < 0.05 vol%/h; purifier subsystem leak rate < 1×10⁻⁵ mbar·L/s; all vacuum lines constructed from SUS304 tubing with KF-40 flanged connections.
- Redundant filtration: two circular HEPA filters (≥99.99% @ 0.3 µm) integrated into the internal recirculation path ensure particulate-free operation essential for OLED fabrication, battery electrode handling, and pharmaceutical processing.
- Modular organic adsorption unit with 10 kg activated carbon and three KF-40 manual bypass valves allows selective removal of volatile organic compounds without interrupting main gas flow—critical for solvent-intensive synthesis or coating processes.
Sample Compatibility & Compliance
This glovebox accommodates a broad range of sensitive materials—including air-sensitive organometallics, lithium metal anodes, perovskite precursors, hygroscopic APIs, and radioactive isotopes—within its chemically inert, particle-controlled workspace. All wetted components are fabricated from ASTM A240-certified SUS304 stainless steel, compliant with ISO 14644-1 Class 5 (ISO Class 5) cleanroom particulate limits when operated with active HEPA recirculation. The system supports regulatory adherence in pharmaceutical development (USP , ICH Q5D), battery R&D (IEC 62660-1), and nuclear research (ANSI N13.1). Optional integration of 21 CFR Part 11-compliant electronic signatures and audit trail export (CSV/Excel) is available via firmware upgrade.
Software & Data Management
The embedded PLC controller records operational metadata—including pressure setpoints, sensor readings (H₂O/O₂), regeneration initiation/completion timestamps, antechamber cycle logs, and alarm events—with timestamped entries stored onboard for ≥12 months. Data export is supported via USB port (CSV format) or optional Ethernet module (Modbus TCP). Sensor calibration intervals are tracked automatically; deviation alerts trigger configurable visual/audible warnings. No cloud dependency or proprietary software installation is required—data integrity is preserved locally with write-protected memory architecture.
Applications
- Lithium-ion and solid-state battery research: electrode drying, electrolyte formulation, and cell assembly under O₂/H₂O <1 ppm conditions to prevent parasitic side reactions.
- OLED/PLED manufacturing: encapsulation of emissive layers, evaporation of thermally sensitive small molecules, and photolithography alignment in particle-free nitrogen environments.
- Pharmaceutical development: handling of oxygen-labile active pharmaceutical ingredients (APIs), lyophilization support, and sterile powder weighing under ISO Class 5-equivalent conditions.
- Nuclear and radiochemistry: containment of alpha/beta emitters, glovebox-integrated gamma spectroscopy setups, and hot-cell precursor synthesis.
- Advanced materials synthesis: Grignard reagent preparation, transition-metal catalysis, MOF crystallization, and air-sensitive nanomaterial handling.
- High-precision metrology: positioning of X-ray detectors (e.g., position-sensitive silicon drift detectors) where ambient humidity induces signal drift or window fogging.
FAQ
What inert gases are compatible with this glovebox?
Nitrogen, argon, and helium are fully supported. Hydrogen-containing regeneration mixtures (N₂/H₂ or Ar/H₂, 3–5% H₂) are used exclusively within the purifier loop and do not enter the main chamber.
How long does it take to achieve <100 ppm O₂ after atmospheric breach?
The automated purge system reduces oxygen concentration to below 100 ppm(v) within 60 minutes, assuming standard chamber volume and initial ambient exposure.
Is the system suitable for GMP-regulated environments?
Yes—when configured with optional audit-trail logging, user access controls, and electronic signature capability, it meets foundational requirements for GMP Annex 11 and FDA 21 CFR Part 11 compliance.
Can the glovebox be integrated with external analytical instruments?
Yes—five KF-40 feedthrough ports (two reserved, one each for gas inlet/outlet/electrical) enable seamless integration with FTIR, Raman probes, or in situ XRD systems.
What maintenance is required for the purification system?
Purifier regeneration is fully automated; routine maintenance includes quarterly HEPA filter replacement, annual oxygen/moisture sensor calibration, and biannual inspection of vacuum pump oil and O-rings.
