Shanghai Youyi GZF-6150B High-Temperature Vacuum Drying Oven

Overview

The Shanghai Youyi GZF-6150B High-Temperature Vacuum Drying Oven is an engineered solution for thermal processing under controlled low-pressure environments, designed specifically for applications requiring precise temperature stability up to 500°C without oxidative degradation. Operating on the principle of vacuum-assisted thermal desorption, this oven eliminates ambient oxygen and reduces solvent boiling points—enabling safe, efficient dehydration of thermally labile, oxidation-sensitive, or compositionally complex samples. Its robust chamber architecture—featuring a fully welded 304 stainless steel interior and cold-rolled steel exterior with electrostatic powder coating—ensures long-term dimensional stability and corrosion resistance under repeated thermal cycling. Unlike convection-based ovens, the GZF-6150B relies on conductive and radiative heat transfer within a sealed, evacuated environment, minimizing convective disturbance to powders, granules, or porous substrates while maintaining uniform thermal distribution across the 150 L working volume.

Key Features

• Microprocessor-based PID temperature controller with 0.1°C resolution and ±1°C uniformity across the full 500°C operating range
• 4.3-inch LCD interface supporting multi-parameter real-time display, intuitive menu navigation, and user-defined program storage
• Power-fail recovery function preserving setpoints and operational state during unexpected interruptions
• Integrated silicone rubber door gasket with adjustable compression mechanism ensuring consistent vacuum integrity down to ≤133 Pa
• Aluminum alloy heating plates fabricated via precision stamping—resistant to high-temperature oxidation and optimized for rapid, uniform thermal conduction
• Dual independent safety systems: programmable over-temperature cutoff and hardware-limited secondary thermostat for fail-safe operation
• Natural convection design eliminates internal airflow, preventing displacement of fine particulates or fragile specimens during drying

Sample Compatibility & Compliance

The GZF-6150B accommodates diverse sample formats—including ceramic precursors, pharmaceutical intermediates, battery electrode slurries, catalyst supports, and sterilized glassware—without risk of thermal decomposition or surface oxidation. Its inert atmosphere capability (compatible with optional N₂ purge and pressure-regulated gas inlet) supports processes aligned with ISO 14644-1 cleanroom material conditioning and ASTM E145-22 standards for gravity-convection and vacuum ovens. The unit meets general electrical safety requirements per IEC 61010-1 and is suitable for GLP-compliant laboratories where traceability of thermal exposure parameters is essential. While not certified to FDA 21 CFR Part 11 out-of-the-box, its programmable controller logs timestamped setpoint history—enabling manual audit trail reconstruction when integrated into validated workflows.

Software & Data Management

The embedded control system supports up to five programmable segments per cycle, allowing ramp-hold-cool profiles tailored to multi-stage drying protocols. Optional RS485 communication enables integration with SCADA or LIMS platforms for centralized monitoring. All temperature setpoints, dwell times, and alarm events are stored in non-volatile memory. For regulated environments, users may configure periodic data export via USB to external storage for archiving—supporting basic electronic record retention practices. Vacuum level monitoring is performed via analog gauge (standard) or digital vacuum controller (optional), with automatic pressure hold functionality to maintain process consistency during extended cycles.

Applications

• Drying of moisture- or solvent-sensitive active pharmaceutical ingredients (APIs) prior to lyophilization or tablet compression
• Thermal aging studies of polymer composites and elastomers under inert conditions
• Pre-treatment of metal oxide catalysts and MOF frameworks to remove physisorbed water without structural collapse
• Post-cleaning drying of precision mechanical components, MEMS devices, and optical substrates
• Residual solvent removal from lithium-ion battery cathode materials (e.g., NMC, LFP) prior to electrode calendering
• Low-oxygen annealing of semiconductor thin films and photovoltaic absorber layers
• Sterilization and depyrogenation of borosilicate glass vials and ampoules in research-scale bioprocessing

FAQ

What is the maximum continuous operating temperature of the GZF-6150B?
The unit is rated for sustained operation at 500°C, with thermal insulation and sealing systems validated for long-duration exposure at this upper limit.
Can the oven be operated under nitrogen or argon atmosphere?
Yes—optional inert gas inlet kits (including needle valve and mass flow meter) enable controlled purging and dynamic pressure regulation during heating cycles.
Is vacuum pump included with the standard configuration?
No—the vacuum pump is offered as a separate accessory; recommended configurations include 2 L/s or 4 L/s dual-stage rotary vane pumps compatible with ≤133 Pa ultimate vacuum.
How many shelf positions are available inside the chamber?
The GZF-6150B includes two adjustable stainless steel trays, with additional tray sets available as accessories to optimize vertical space utilization.
Does the controller support data logging to external media?
Yes—via USB port, users can export temperature and time-stamped event logs in CSV format for post-processing and quality documentation.
