Abner VGB-4A Vacuum Glove Box (Refurbished, 98% New)

Overview

The Abner VGB-4A Vacuum Glove Box is a production-grade inert atmosphere enclosure engineered for reliable operation in R&D laboratories, pilot-scale synthesis, and controlled manufacturing environments requiring strict exclusion of oxygen, moisture, or ambient contaminants. Built on a robust stainless steel (AISI 304) monocoque chassis, the system operates on a dual-mode gas management principle—capable of both vacuum purging and continuous inert gas recirculation via integrated purification columns. Its design adheres to fundamental glove box engineering standards: negative/positive pressure stability, leak integrity ≤1×10⁻⁵ mbar·L/s (helium-tested), and dynamic equilibrium control of O₂ and H₂O levels below 1 ppm (achievable with optional Pd-catalyst and molecular sieve modules). The VGB-4A is not a benchtop unit; its 0.75 m³ internal volume and modular interface ports support integration with Schlenk lines, solvent purification systems, battery electrode coaters, and glove-compatible analytical tools—making it suitable for lithium-ion battery material handling, air-sensitive organometallic synthesis, and high-purity thin-film deposition pre-processing.

Key Features

• Structural integrity: 3-mm-thick AISI 304 stainless steel chamber with TIG-welded seams and electropolished interior surface for corrosion resistance and low particle shedding.
• Sealing architecture: Dual-layer silicone elastomer gloves (thickness: 0.4 mm, tensile strength ≥7 MPa) mounted on ISO-KF 160 flanges with mechanical clamping and secondary O-ring backup seals.
• Gas handling system: Integrated two-stage purification train (oxygen scavenger + desiccant), programmable gas flow controller (0–20 L/min adjustable), and automatic pressure regulation (±0.5 mbar setpoint accuracy).
• Operational safety: Interlocked door mechanism with vacuum/pressure status feedback, emergency venting valve, and real-time O₂/H₂O sensor outputs (RS-485 Modbus interface).
• Refurbishment standard: Fully reconditioned per Abner’s Certified Pre-Owned Protocol—including full leak testing, glove replacement, sensor calibration traceable to NIST standards, and 72-hour functional burn-in under nitrogen purge.

Sample Compatibility & Compliance

The VGB-4A accommodates samples ranging from gram-scale catalysts to 6-inch wafer substrates, with configurable internal mounting rails and utility passthroughs (electrical, pneumatic, optical fiber). It complies with general laboratory safety requirements per GB/T 34066-2017 (Chinese standard for glove box performance testing) and meets baseline mechanical safety criteria aligned with IEC 61010-1:2010 for electrical equipment in laboratory use. While not certified to UL or CE for standalone sale in North America/EU, its architecture supports retrofitting to meet ASTM E506-22 (Standard Guide for Selection and Use of Inert Atmosphere Glove Boxes) and ISO 14644-1 Class 5 cleanroom particulate limits when operated with HEPA-filtered recirculation mode. Documentation includes full refurbishment report, calibration certificates for O₂/H₂O sensors, and material compliance declarations (RoHS, REACH).

Software & Data Management

The VGB-4A operates via a dedicated embedded controller with local touchscreen HMI (7-inch resistive LCD, IP65-rated). All process parameters—including chamber pressure, purge cycle count, gas flow rate, and real-time O₂/H₂O concentration—are logged at 1-second intervals to internal flash memory (≥12 months data retention). Export is supported via USB 2.0 (CSV format) or optional Ethernet module (TCP/IP Modbus TCP). Audit trail functionality satisfies GLP-compliant recordkeeping requirements: each parameter change is timestamped, user-ID tagged (with password-protected admin access), and immutable upon export. No cloud connectivity or proprietary software installation is required—data files are natively readable in Excel or LabVIEW.

Applications

• Lithium battery R&D: Electrode slurry preparation, coin-cell assembly, and anode/cathode material storage under <0.1 ppm O₂/H₂O.
• Organometallic chemistry: Handling of pyrophoric reagents (e.g., t-BuLi, DIBAL-H), Grignard reactions, and transition metal catalysis.
• Materials science: Synthesis and characterization of MOFs, perovskites, and 2D nanomaterials requiring sub-ppm environmental control.
• Electronics manufacturing: Sensitive component packaging, flux-free soldering pre-process, and MEMS device handling.
• Pharmaceutical development: Moisture-sensitive API crystallization, lyophilized powder transfer, and sterile formulation under inert blanket.

FAQ

Is this unit certified to ISO or ASTM standards?
The VGB-4A conforms to performance benchmarks defined in ASTM E506-22 and GB/T 34066-2017. Full certification documentation (leak test reports, sensor calibration certs) is provided with delivery.
What is included in the refurbishment process?
All consumables (gloves, filters, O-rings) are replaced; chamber interior is passivated and inspected; pressure/vacuum actuators are recalibrated; and the unit undergoes 72 hours of continuous inert gas operation with live monitoring.
Can the system be upgraded with additional purification modules?
Yes—the base configuration supports field installation of optional hydrogenation catalyst cartridges, ultra-low moisture desiccant beds, or VOC scrubbers via standardized ISO-KF 40 ports.
Does it support integration with external equipment?
Standardized 6-mm and 12-mm utility feedthroughs (electrical, vacuum, gas) and four ISO-KF 160 ports enable seamless connection to glove-compatible reactors, mass spectrometers, or glove-port microscopes.
What warranty is offered on this refurbished unit?
Abner provides a 12-month limited warranty covering parts and labor for defects in materials or workmanship, commencing from date of commissioning verification.
