Plas-labs 818-GBB Dual-Operator Glove Box System

Overview

The Plas-labs 818-GBB Dual-Operator Glove Box System is an engineered inert atmosphere enclosure designed for rigorous research applications requiring simultaneous operator access, ultra-low moisture and oxygen environments, and long-term process stability. Built upon a monolithic 304 stainless steel chassis with seamless welded construction and electropolished interior surfaces, the 818-GBB employs a dual-chamber architecture comprising a primary work chamber (1157 L internal volume) and a dedicated transfer chamber (26.9 L). Its operational principle relies on continuous inert gas (N₂ or Ar) purging coupled with integrated gas purification—typically via heated copper catalyst and molecular sieve beds—to achieve and sustain oxygen levels below 1 ppm and residual humidity below 0.001% RH. The system complies with ISO 14644-1 Class 5 (ISO Class 5) cleanroom performance benchmarks when operated under validated purge protocols and is routinely deployed in GMP-aligned pharmaceutical development, battery electrode fabrication, organometallic synthesis, and anaerobic microbiology workflows where ambient atmospheric interference must be eliminated.

Key Features

• Dual-operator configuration with four ergonomically spaced glove ports (Ø16.5 cm), each sealed with medical-grade Hypalon® gloves offering superior chemical resistance, low permeability to H₂O/O₂, and extended service life under repeated flexing.
• Beveled 6.4 mm optical acrylic viewing window eliminates parallax distortion and supports unobstructed visual monitoring of manipulations; surface-hardened for scratch resistance and compatibility with ethanol/isopropanol decontamination.
• Front-access 30.5 cm diameter sample loading port with vacuum-tight valve lock enables introduction of large instrumentation (e.g., small reactors, glovebox-integrated XRD stages) without compromising chamber integrity.
• Integrated transfer chamber with analog vacuum gauge and independent purge control allows safe material exchange while maintaining stable internal atmosphere—critical for air-sensitive reagents, Li-metal anodes, or obligate anaerobes.
• UL/CSA-listed 220 V, 60 Hz multi-outlet power strip with medical-grade isolation supports concurrent operation of balances, peristaltic pumps, stirrers, or environmental sensors inside the chamber.
• Gel-sealed top and base panels utilize non-silicone, non-cytotoxic polyacrylamide-based sealing compound—certified non-pyrogenic and compliant with USP endotoxin limits—preventing microbial ingress and eliminating silicone outgassing risks in semiconductor or biopharma applications.

Sample Compatibility & Compliance

The 818-GBB accommodates heterogeneous sample geometries—from powder vials and electrochemical cells to live-cell culture flasks and microelectronics wafers—via its spacious internal footprint (152 × 79 × 96 cm) and modular accessory mounting rails. All wetted materials meet FDA 21 CFR Part 11 requirements for traceability when paired with optional data-logging purge controllers. The system conforms to ASTM E493–21 (Standard Practice for Leak Testing of Vacuum Vessels), ISO 10648-2:1994 (Cleanrooms—Part 2: Classification of Air Cleanliness), and EU GMP Annex 1 (2022) provisions for containment of potent compounds. Optional HEPA/ULPA filtration upgrades enable ISO Class 4 particulate control. Surface finish adheres to ASME BPE-2022 standards for hygienic design in bioprocessing environments.

Software & Data Management

While the base 818-GBB operates via manual valve control and analog instrumentation, it is fully compatible with Plas-labs’ optional GloveBoxLink™ digital interface module (sold separately). This module integrates real-time O₂/H₂O sensor telemetry (via TDLAS or electrochemical probes), automated purge sequencing, alarm-triggered nitrogen dump protocols, and audit-trail-enabled data export compliant with 21 CFR Part 11 electronic records requirements. Sensor calibration certificates are NIST-traceable, and firmware updates follow IEC 62304 Class B medical device software lifecycle standards.

Applications

• Electrode fabrication and testing for solid-state lithium batteries under O₂/H₂O <1 ppm conditions.
• Handling of pyrophoric catalysts (e.g., Ni(COD)₂, Cp₂ZrCl₂) and Grignard reagents in synthetic organic chemistry.
• Cultivation and manipulation of strict anaerobes (e.g., Clostridium difficile, Methanobrevibacter smithii) in microbiome research.
• Encapsulation of OLED materials and perovskite thin films during R&D-scale deposition.
• Stabilization and weighing of hygroscopic reference standards (e.g., KHP, NaCl) for metrology labs.
• Containment of high-potency active pharmaceutical ingredients (HPAPIs) during early-phase formulation development.

FAQ

What inert gas supply specifications are required for optimal performance?
A minimum inlet pressure of 60–100 psig (4.1–6.9 bar) with dew point ≤ –70°C and O₂ ≤ 1 ppm is recommended. A dedicated high-purity gas source with dual-stage regulator and particulate filter is mandatory.
Can the 818-GBB be retrofitted with automated atmosphere monitoring?
Yes—GloveBoxLink™ digital interface supports integration of third-party O₂/H₂O analyzers (e.g., Michell Easidew, Systech Illinois) and enables configurable alarm thresholds with email/SMS notification via Ethernet.
Is the gel seal compatible with autoclaving or vaporized hydrogen peroxide (VHP) decontamination?
The polyacrylamide-based seal is VHP-compatible (≤1000 ppm, 60% RH, 25°C exposure) but not autoclavable; replacement seals are supplied sterile-packaged per ISO 11135.
What maintenance intervals are specified for the gas purification system?
Copper catalyst beds require regeneration every 6–12 months depending on usage; molecular sieves should be replaced annually or after 2000 hr of continuous operation—logbook entries are supported by optional GloveBoxLink™.
Does the system support integration with external fume hoods or HVAC systems?
Yes—the exhaust line features a 50 mm (2″) NPT port compatible with standard lab exhaust manifolds; backpressure must remain <25 Pa to maintain rated leak integrity per ASTM E493.
