Shanghai Youyi GZF-6050BL High-Temperature Vertical Vacuum Drying Oven (50 L, 500 °C)

Overview

The Shanghai Youyi GZF-6050BL is a high-temperature 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 points of solvents and volatile components—while maintaining tightly controlled elevated temperatures up to 500 °C. This dual-control capability enables rapid, uniform, and oxygen-free drying, baking, sterilization, and thermal treatment of heat-sensitive, oxidation-prone, or compositionally complex samples. Unlike conventional convection ovens, the GZF-6050BL eliminates convective air currents that may displace fine powders or disturb delicate structures, making it especially suitable for applications requiring inert-atmosphere stability—such as catalyst activation, ceramic pre-sintering, battery electrode drying, and residual solvent removal from pharmaceutical intermediates.

Key Features

• Robust vertical architecture with 50 L usable chamber volume and optimized internal geometry for enhanced thermal homogeneity and accessibility.
• 304 stainless steel interior chamber and reinforced cold-rolled steel exterior with electrostatic powder coating for corrosion resistance and long-term structural integrity.
• PID-based microprocessor temperature controller with 0.1 °C resolution, ±1 °C uniformity, and programmable ramp/soak profiles; includes over-temperature cut-off protection and power-failure data retention.
• Integrated silicone door gasket with adjustable compression mechanism ensures reliable sealing at ≤133 Pa vacuum level; compatible with nitrogen or argon purging via optional inert gas inlet kit.
• High-efficiency aluminum heating plates—formed via precision stamping—deliver rapid thermal response and minimal thermal gradient across load zones.
• 4.3-inch backlit LCD interface displaying real-time temperature, vacuum status, elapsed time, and setpoint in a single-view menu-driven layout.

Sample Compatibility & Compliance

The GZF-6050BL accommodates a broad spectrum of sample formats—including powders, granules, thin-film coatings, porous ceramics, metal oxides, and glassware—without mechanical displacement or surface oxidation. Its oxygen-free operation supports ASTM E145-22 (Standard Specification for Gravity-Convection and Forced-Ventilation Ovens) and ISO 12782-2 (Plastics — Determination of water absorption — Part 2: Vacuum method) methodologies. When configured with optional inert gas inlet and automatic pressure regulation, the system meets GLP-compliant workflow requirements for trace moisture analysis and residual solvent quantification per USP . The stainless steel chamber complies with FDA-recommended material standards for non-reactive contact surfaces in pharmaceutical development environments.

Software & Data Management

While the base model features standalone PID control, optional upgrades include a multi-segment programmable temperature controller supporting up to 30 steps with user-defined ramp rates and dwell times. Vacuum monitoring can be enhanced with a digital vacuum gauge and auto-compensation module (maintaining setpoint pressure within ±5 Pa tolerance). All operational parameters—including temperature logs, vacuum cycles, and alarm events—are timestamped and stored internally for ≥30 days. Export-capable USB interface allows transfer of CSV-formatted datasets for integration into LIMS or QA/QC documentation systems compliant with 21 CFR Part 11 audit-trail requirements.

Applications

• Drying and degassing of lithium-ion battery cathode/anode slurries prior to calendaring.
• Thermal conditioning of zeolites, MOFs, and other porous adsorbents under inert atmosphere.
• Residual solvent removal from API crystallization batches without thermal decomposition.
• Pre-oxidation stabilization of carbon fiber precursors and ceramic green bodies.
• Sterilization and moisture elimination from laboratory glassware, filtration membranes, and sensor housings.
• Accelerated aging studies of polymer composites and encapsulated electronic components.

FAQ

What is the maximum allowable operating temperature, and how is thermal stability maintained at 500 °C?
The GZF-6050BL is rated for continuous operation at 500 °C. Thermal stability is ensured through dual-layer insulation, high-emissivity aluminum heating elements, and a feedback-controlled PID loop with redundant thermocouple inputs.
Can this oven be used under nitrogen or argon purge?
Yes—optional inert gas inlet valves and mass flow controllers enable controlled atmosphere operation; compatibility with standard CGA-580 fittings simplifies integration into existing lab gas networks.
Is the vacuum pump included with the system?
The unit includes mounting provisions and electrical interfaces for external vacuum pumps (2 L/s or 4 L/s models recommended); pumps are available as configurable accessories.
Does the oven support validation protocols for regulated environments?
With optional IQ/OQ documentation packages and calibrated sensor certificates, the system supports installation and operational qualification per ISO/IEC 17025 and GMP Annex 15 guidelines.
How many shelf levels are provided, and are additional trays available?
Three 304 stainless steel shelves are standard; custom-sized trays and perforated variants are available upon request to accommodate specialized fixtures or high-volume throughput.
