Overview
The Shanghai Youyi GZF-6250AL is a vertically oriented, high-temperature vacuum drying oven engineered for precision thermal processing under reduced-pressure environments. It operates on the principle of vacuum-assisted thermal desorption—lowering the partial pressure of volatile components to reduce their boiling points, thereby enabling efficient moisture and solvent removal from thermally sensitive, oxidation-prone, or structurally complex samples without thermal degradation. Designed for laboratory-scale R&D, QC/QA validation, and pilot-scale material conditioning, the GZF-6250AL supports applications requiring inert-atmosphere processing up to 400 °C, including pre-baking of electronic components, degassing of composites, stabilization of catalysts, and residual solvent removal from pharmaceutical intermediates per ICH Q5C guidelines.
Key Features
- Robust vertical architecture with 252 L effective chamber volume (600 × 600 × 700 mm internal dimensions), optimized for uniform heat distribution and ergonomic loading/unloading.
- Microprocessor-based PID temperature controller with 0.1 °C resolution, ±1 °C stability across the full operating range (RT+10 to 400 °C), and programmable ramp-soak profiles.
- 304 stainless steel chamber interior and cold-rolled steel exterior with electrostatic powder coating—corrosion-resistant, non-reactive, and compliant with ISO 14644-1 Class 8 cleanroom-compatible surface finish standards.
- Integrated silicone rubber door gasket with adjustable clamping mechanism, achieving and maintaining ≤133 Pa ultimate vacuum level per ASTM E104-02 test methodology.
- Aluminum heating plates fabricated via precision stamping—high thermal conductivity, minimal oxidation at elevated temperatures, and low thermal mass for rapid response and energy efficiency.
- 4.3-inch LCD interface with multi-parameter display (setpoint, actual temperature, vacuum level, elapsed time, remaining time), intuitive menu navigation, and real-time event logging.
- Power-fail recovery function preserving all active parameters and program states; automatic restart upon power restoration without manual reconfiguration.
Sample Compatibility & Compliance
The GZF-6250AL accommodates diverse sample formats—including powders, granules, thin films, porous ceramics, metal foams, glassware, and assembled microelectromechanical systems (MEMS)—without displacement or particle dispersion, eliminating risks associated with forced-air convection. Its oxygen-free operation prevents oxidative decomposition during thermal treatment of lithium-ion battery cathode precursors (e.g., NMC, LFP), polymer additives, or organometallic complexes. The system supports GLP/GMP-aligned workflows through optional audit-trail-enabled software (with 21 CFR Part 11-compliant electronic signatures) and is compatible with inert gas purging (N₂ or Ar) via add-on inlet valves. All materials in contact with the chamber conform to USP extractables profiling requirements.
Software & Data Management
The standard control system includes embedded data logging (timestamped temperature and vacuum values at user-defined intervals), exportable via USB to CSV format. Optional upgrades include a programmable logic controller (PLC)-based multi-segment temperature/vacuum scheduler, auto-regulating vacuum maintenance module (maintains setpoint pressure ±5 Pa), and independent over-temperature cut-off circuitry certified to IEC 61000-4-2 EMC immunity standards. When integrated with Shanghai Youyi’s LabLink™ platform, the oven supports remote monitoring, alarm notification via email/SMS, and traceable calibration certificate generation aligned with ISO/IEC 17025 documentation frameworks.
Applications
- Drying of heat-labile biological matrices (e.g., lyophilized enzyme formulations, vaccine adjuvants) without denaturation.
- Thermal aging studies of aerospace-grade epoxies and polyimides under controlled vacuum and inert atmosphere.
- Pre-conditioning of humidity-sensitive sensors and optical coatings prior to deposition or packaging.
- Residual solvent analysis preparation for GC-MS quantification in API manufacturing (per USP <467>).
- Outgassing of ultra-high vacuum (UHV) components used in semiconductor fabrication tools.
- Stabilization of nanomaterial dispersions and MOF frameworks prior to BET surface area characterization.
FAQ
What vacuum level can the GZF-6250AL achieve without optional pump upgrades?
The base configuration achieves ≤133 Pa using the included 2 L/s vacuum pump, verified per ISO 21360-1 methodology.
Is the chamber suitable for use with corrosive vapors such as HCl or HF?
No—standard 304 stainless steel is not resistant to halogenated acids; optional 316L-lined chambers or Hastelloy C-276 inserts are available upon request.
Can the oven be validated for IQ/OQ/PQ protocols?
Yes—factory-supplied validation templates, sensor calibration certificates (NIST-traceable Pt100 and capacitance manometer), and FAT reports are provided.
Does the system support continuous inert gas flow during operation?
Yes—when equipped with the optional inert gas inlet valve and mass flow controller (0–10 L/min N₂/Ar), enabling dynamic purge cycles.
What safety certifications does the unit carry?
CE-marked per EN 61000-6-2 (immunity) and EN 61000-6-4 (emissions); conforms to UL 61010-1 third-party recognized component requirements for laboratory equipment.
