Shanghai Youyi GZF-6090AL High-Temperature Vacuum Drying Oven

Overview

The Shanghai Youyi GZF-6090AL High-Temperature Vacuum Drying Oven is an engineered solution for controlled thermal processing under reduced-pressure environments. Designed around the fundamental principle of vacuum-assisted thermal desorption, this oven eliminates convective heat transfer and lowers solvent boiling points—enabling rapid, uniform drying of thermally sensitive, oxidation-prone, or structurally complex samples without degradation. Its operational envelope spans from ambient +10°C to 400°C, with precise microprocessor-based PID temperature regulation ensuring stability within ±1°C across the full range. The chamber’s 90 L internal volume (450 × 450 × 450 mm), constructed entirely from electropolished 304 stainless steel, supports reproducible, contamination-free processing in compliance with GLP-aligned laboratory workflows. Unlike forced-air ovens, the GZF-6090AL operates without internal air circulation—preventing particle displacement, oxidation, or thermal decomposition during extended high-temperature holds.

Key Features

• Microprocessor-controlled PID temperature regulation with 0.1°C resolution and programmable ramp/soak profiles
• Dual-stage safety architecture: independent over-temperature cut-off and power-failure data retention with auto-recovery function
• 4.3-inch backlit LCD interface displaying real-time temperature, setpoint, vacuum level (optional digital readout), timer, and system status
• Hermetically sealed chamber with one-piece molded silicone door gasket, adjustable compression mechanism, and vacuum-tight latch system
• Aluminum heating plates fabricated via precision stamping—resistant to oxidation up to 400°C and optimized for thermal conductivity and uniformity
• Integrated vacuum connection port (KF16 or ISO-KF25 compatible) with standard flange for direct coupling to rotary vane or diaphragm vacuum pumps
• Robust mechanical construction: cold-rolled steel exterior with epoxy-polyester electrostatic coating; reinforced structural frame for long-term dimensional stability

Sample Compatibility & Compliance

The GZF-6090AL accommodates a broad spectrum of sample formats—including powders, granules, thin-film coatings, porous ceramics, metal sintered parts, lyophilized biological matrices, and cleaned precision components. Its inert atmosphere capability (when paired with optional inert gas inlet valve and mass flow controller) enables processing per ASTM E145–22 (Standard Specification for Gravity-Convection and Forced-Ventilation Ovens) and ISO 12100–2010 (Safety of machinery). While not certified to UL/CSA or IEC 61010–1 out-of-the-box, the unit meets essential electrical safety requirements for Class I equipment and may be validated for use in GMP-regulated environments when integrated into documented IQ/OQ/PQ protocols. Vacuum performance (≤133 Pa) satisfies typical requirements for moisture removal from hygroscopic materials per USP on package integrity testing and ASTM D257–21 for dielectric material conditioning.

Software & Data Management

The GZF-6090AL supports optional multi-segment programmable controllers (up to 30 segments, 99 cycles) with RS485 Modbus RTU output for integration into centralized lab monitoring systems (e.g., LabVantage, Siemens Desigo, or custom SCADA). Digital vacuum control modules provide closed-loop pressure regulation with auto-compensation for outgassing events. All temperature and timing parameters are logged internally with timestamped records (non-volatile memory), supporting audit trails required under FDA 21 CFR Part 11 when paired with compliant third-party software. Optional Ethernet or USB data export allows CSV-formatted reports for traceability in quality documentation systems.

Applications

• Drying and degassing of lithium-ion battery electrode slurries and separator films prior to calendaring
• Thermal stabilization of catalyst precursors and MOF frameworks under inert purge conditions
• Residual solvent removal from pharmaceutical intermediates without racemization or polymorphic transition
• Moisture conditioning of optical-grade quartz substrates and MEMS packaging components
• Post-cleaning drying of surgical instruments and reusable labware in ISO 13485-certified facilities
• Accelerated aging studies of polymer composites and encapsulants under controlled low-oxygen thermal stress
• Pre-baking of vacuum chamber components and ultra-high-purity semiconductor fixtures

FAQ

What vacuum pump specifications are recommended for optimal performance with the GZF-6090AL?
A two-stage rotary vane pump rated at ≥4 L/s (at 50 Hz) is recommended for achieving ≤133 Pa within ≤30 minutes under typical load conditions. For applications requiring faster pump-down or operation below 10 Pa, a secondary turbomolecular or dry scroll pump may be added in series.
Can the GZF-6090AL be validated for GMP manufacturing use?
Yes—when equipped with calibrated PT100 sensors, digital vacuum transducers, and audit-trail-capable controllers, the unit can undergo IQ/OQ/PQ qualification per Annex 15 and ISO/IEC 17025 guidelines. Documentation templates and calibration certificates are available upon request.
Is inert gas purging supported natively?
The base model includes a standard NPT 1/4″ inlet port. Optional inert gas kits (stainless steel needle valve + digital mass flow meter, 0–1000 sccm range) enable automated N₂ or Ar purging sequences synchronized with vacuum cycles.
How is temperature uniformity verified across the chamber volume?
Uniformity is confirmed per ASTM E2203–18 using nine calibrated thermocouples placed at standardized locations (center + six face centers + two corners). Typical measured deviation remains within ±0.8°C at 300°C after 60-minute equilibration.
Are replacement parts such as door gaskets and heating plates available separately?
Yes—original-specification silicone gaskets (FDA-compliant grade), 304 stainless steel inner liners, and anodized aluminum heating plates are stocked and shipped globally with lead times under 10 business days.
