Shanghai Youyi GZF-6090BL High-Temperature Vacuum Drying Oven (500°C, 90L)

Overview

The Shanghai Youyi GZF-6090BL is a high-performance vertical vacuum drying oven engineered for precise thermal processing under reduced-pressure environments. Designed around the fundamental principle of vacuum-assisted thermal desorption, it operates by lowering the ambient pressure inside the chamber—thereby reducing the boiling point of volatile components—and applying controlled, uniform conductive heating via electric resistance elements embedded in reinforced stainless-steel walls and aluminum heat-distribution plates. This dual-mode operation enables rapid, residue-free removal of moisture, solvents, or adsorbed gases from thermally sensitive, oxidation-prone, or structurally complex samples—including pharmaceutical intermediates, catalyst precursors, battery electrode slurries, ceramic green bodies, and polymer composites—without thermal degradation or surface oxidation. Its maximum operating temperature of 500°C meets stringent requirements for high-temperature annealing, pre-sintering, and residual solvent elimination in advanced materials R&D and quality control laboratories.

Key Features

• Robust 90-liter working chamber constructed entirely from electropolished AISI 304 stainless steel—resistant to corrosion, thermal cycling, and outgassing at elevated temperatures
• PID-controlled microprocessor temperature system with 0.1°C resolution, ±1°C uniformity across the chamber, and programmable ramp-soak profiles
• Integrated mechanical vacuum sealing system featuring a one-piece molded silicone gasket and adjustable door-tightening mechanism, ensuring stable vacuum integrity ≤133 Pa
• High-efficiency aluminum heating plates fabricated via precision stamping—exhibiting minimal thermal oxidation up to 500°C and optimized thermal conductivity for rapid, uniform heat transfer
• 4.3-inch backlit LCD interface supporting multi-parameter real-time display (chamber temperature, setpoint, elapsed time, vacuum level), intuitive menu navigation, and data logging capability
• Comprehensive safety architecture including independent over-temperature cutoff, power-failure parameter retention with auto-restart functionality, and audible/visual alarm triggers

Sample Compatibility & Compliance

The GZF-6090BL accommodates diverse sample formats: powders, granules, thin films, porous ceramics, assembled electronic components, glassware, and multi-layer composite substrates. Its oxygen-free processing environment eliminates oxidative decomposition pathways—critical for handling lithium-ion battery cathode materials (e.g., NMC, LFP), metal-organic frameworks (MOFs), perovskite precursors, and enzymatic formulations. The unit complies with general laboratory equipment design standards per IEC 61010-1 (Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use). While not certified to ISO/IEC 17025 or GLP as a standalone instrument, its operational repeatability, traceable temperature calibration options, and audit-ready data logging support integration into regulated workflows aligned with USP , ASTM E145, and ISO 12099 for moisture content determination and thermal stability assessment.

Software & Data Management

The embedded controller supports optional RS485/Modbus RTU communication for integration into centralized lab management systems. When paired with the optional multi-segment programmable temperature controller, users can define up to 32-step heating/cooling/vacuum-hold sequences with time- and temperature-triggered events. Vacuum monitoring is provided via analog gauge (standard) or digital vacuum transducer (optional), with automatic pressure regulation available via integrated inert gas (N₂ or Ar) inlet valve and mass flow controller. All operational parameters—including actual temperature, setpoint, vacuum level, cycle time, and alarm status—are timestamped and stored internally for ≥10,000 records. Export is supported via USB flash drive in CSV format, enabling post-processing in MATLAB, Python, or LIMS platforms. Audit trail functionality satisfies basic FDA 21 CFR Part 11 requirements when deployed with user-access controls and electronic signature protocols.

Applications

• Drying and degassing of high-purity ceramic powders prior to hot isostatic pressing (HIP) or sintering
• Residual solvent removal from coated electrodes in battery R&D and pilot-scale manufacturing
• Thermal conditioning of optical lenses and infrared detector housings to prevent micro-condensation
• Stabilization of hygroscopic reference standards (e.g., potassium hydrogen phthalate, sodium chloride) under inert atmosphere
• Accelerated aging studies of polymer encapsulants and dielectric films under controlled thermal-vacuum stress
• Pre-treatment of MEMS devices and microfluidic chips to eliminate trapped moisture before hermetic sealing

FAQ

What is the maximum allowable vacuum level, and how is it maintained?
The chamber achieves and sustains ≤133 Pa (1 Torr) using a two-stage rotary vane vacuum pump (optional; 2 L/s or 4 L/s models available). A high-integrity silicone gasket and precision-machined flange interface minimize leakage; optional automatic pressure regulation maintains setpoint during extended cycles.
Can this oven be used for inert-gas purging or backfilling?
Yes—when equipped with the optional inert gas inlet valve and mass flow controller, the system supports continuous N₂ or Ar purge, dynamic pressure control, or final inert-atmosphere cool-down to prevent re-oxidation.
Is calibration documentation included, and what standards are supported?
Factory calibration certificates for temperature uniformity and vacuum sensor accuracy are available upon request. Traceability to NIST or CNAS-accredited labs is achievable through third-party calibration services using PT100 probes and capacitance manometers.
How many sample trays are supplied, and what is their load capacity?
Four adjustable 304 stainless-steel trays (450 × 450 mm) are standard, each rated for 15 kg static load at 500°C. Tray spacing is fully customizable to accommodate tall or stacked fixtures.
Does the unit meet CE or UL safety certification requirements?
The GZF-6090BL conforms to IEC 61010-1:2010 for laboratory equipment safety. CE marking is available for EU-bound units with full technical file submission; UL listing requires customer-initiated evaluation under UL 61010-1.
