Shanghai Youyi GZF-6050AL High-Temperature Vacuum Drying Oven

Overview

The Shanghai Youyi GZF-6050AL High-Temperature Vacuum Drying Oven is an engineered solution for controlled thermal processing under reduced-pressure conditions. Designed around the fundamental principle of vacuum-assisted thermal desorption, this oven eliminates convective heat transfer and suppresses oxidative degradation by operating in an oxygen-deficient or inert-gas-purged environment. Its operational temperature range of RT+10°C to 400°C enables precise thermal treatment of thermally sensitive, hygroscopic, or oxidation-prone materials—including pharmaceutical intermediates, catalyst precursors, battery electrode slurries, ceramic green bodies, and polymer composites—without decomposition or surface discoloration. The chamber’s 304 stainless steel construction ensures long-term corrosion resistance against acidic vapors and residual solvents, while the integrated silicone gasket and adjustable door clamping mechanism maintain a stable vacuum integrity of ≤133 Pa—critical for low-boiling-point solvent removal and moisture-sensitive drying protocols.

Key Features

• Microprocessor-based PID temperature controller with 0.1°C resolution and ±1°C uniformity across the working volume;
• 4.3-inch LCD display showing real-time temperature, setpoint, vacuum status, timer, and alarm codes in a single-view interface;
• Programmable power-loss recovery function: automatically resumes prior settings after unexpected shutdowns or grid interruptions;
• Three-tier adjustable stainless steel shelving system (standard configuration), optimized for load distribution and radiant heat exchange;
• Double-walled insulated chamber with high-density mineral wool insulation, minimizing external surface temperature rise and energy consumption;
• Integrated mechanical vacuum gauge (analog pointer type); optional digital vacuum controller with auto-pressure-hold capability available;
• Front-loading vertical design with reinforced cold-rolled steel exterior and electrostatic powder coating for durability and chemical resistance;
• Dual safety architecture: independent overtemperature cut-off (mechanical thermostat) plus electronic limit control compliant with IEC 61000-4 immunity standards.

Sample Compatibility & Compliance

The GZF-6050AL accommodates a broad spectrum of sample formats: powders, granules, thin films, coated substrates, porous ceramics, and assembled microcomponents. Its 50 L internal volume (415 × 370 × 345 mm) supports batch processing of multiple glass vials, crucibles, or custom fixtures without compromising vacuum integrity. All wetted surfaces are electropolished 304 stainless steel, meeting USP Class VI biocompatibility requirements for pharmaceutical R&D applications. The unit complies with GB/T 5170.11–2017 (Chinese national standard for environmental testing equipment) and incorporates design elements aligned with ISO/IEC 17025 laboratory accreditation criteria—particularly in traceability of temperature calibration (NIST-traceable reference sensors available upon request) and documented thermal mapping procedures. Optional inert gas inlet (N₂ or Ar) with mass flow controller enables strict atmosphere control for air-sensitive syntheses and storage stabilization per ASTM D3420 guidelines.

Software & Data Management

While the base model operates via embedded firmware, optional RS485/Modbus RTU communication allows integration into centralized lab monitoring systems (e.g., LabVantage, Siemens Desigo, or custom SCADA). The programmable controller supports up to 30 segments per profile, enabling complex ramp-soak-cool cycles required for solvent gradient drying or annealing protocols. All temperature and timer events are logged internally with timestamping; data export via USB flash drive (optional module) provides CSV-formatted records suitable for 21 CFR Part 11–compliant audit trails when paired with user-defined electronic signatures. Vacuum pressure data can be synchronized with temperature profiles using third-party DAQ hardware, supporting GLP-compliant reporting for QC release testing in regulated environments.

Applications

• Drying of lithium-ion battery cathode/anode materials under inert atmosphere to prevent Li₂CO₃ formation;
• Dehydration of enzyme immobilization matrices without denaturation;
• Post-synthesis solvent removal from MOFs and covalent organic frameworks (COFs);
• Thermal conditioning of optical fiber preforms prior to drawing;
• Residual solvent analysis preparation (e.g., ICH Q3C-compliant residual ethyl acetate removal from APIs);
• Accelerated aging studies of encapsulation resins and conformal coatings;
• Pre-treatment of MEMS packaging substrates to eliminate outgassing contaminants prior to hermetic sealing.

FAQ

What vacuum level is achievable with the standard configuration?
The GZF-6050AL achieves ≤133 Pa using the included 2 L/s rotary vane pump. For sub-10 Pa operation, a 4 L/s pump or optional oil-free scroll pump is recommended.
Can the oven be operated continuously at 400°C?
Yes—the heating elements, insulation, and chamber seals are rated for continuous duty at 400°C. Thermal stability testing confirms drift <±0.5°C over 72-hour runs.
Is validation documentation available for IQ/OQ/PQ protocols?
Factory-installed NIST-traceable temperature sensors and as-built drawings are provided. Full qualification support—including DQ templates and thermal mapping SOPs—is available through Shanghai Youyi’s technical services division.
How is overpressure protection handled during inert gas purging?
A calibrated pressure relief valve (set at 5 kPa gauge) is integrated into the gas inlet manifold to prevent chamber over-pressurization during nitrogen/argon charging.
Are replacement shelves and gaskets available as spare parts?
Yes—304 stainless steel shelves (part #GZF-SH-03), silicone door gaskets (part #GZF-GSK-050), and vacuum gauge assemblies are stocked and shipped globally within 5 business days.
