Shanghai Youyi GZF-6050CL High-Temperature Vacuum Drying Oven (600 °C, 50 L)

Overview

The Shanghai Youyi GZF-6050CL is a vertically oriented, high-temperature vacuum drying oven engineered for precision thermal processing under reduced-pressure environments. Operating at temperatures up to 600 °C and maintaining vacuum levels ≤133 Pa, it enables controlled dehydration, sterilization, degassing, and inert-atmosphere annealing of thermally sensitive, oxidation-prone, or compositionally complex samples. Unlike convection ovens, this system eliminates convective heat transfer and oxygen-mediated degradation by isolating the chamber from ambient air—making it indispensable for applications requiring strict thermal stability, residual solvent removal, or preservation of redox-sensitive compounds. Its design adheres to fundamental principles of vacuum thermodynamics: lowering the boiling point of volatile components while suppressing decomposition kinetics through pressure reduction and uniform radiant heating.

Key Features

• Microprocessor-controlled PID temperature regulation with 0.1 °C resolution and ±1 °C uniformity across the 50 L working chamber;
• Robust 304 stainless steel interior chamber and cold-rolled steel exterior with electrostatic powder coating for corrosion resistance and thermal insulation;
• Integrated high-elasticity silicone door gasket ensuring repeatable vacuum integrity; adjustable door latch mechanism for consistent sealing force;
• 4.3-inch full-color TFT LCD interface supporting multi-segment programmable ramp/soak profiles, real-time parameter monitoring, and event logging;
• Intelligent power recovery function preserving setpoints and operational state after unexpected power interruption;
• Electric resistive heating elements mounted on custom-formed aluminum shelves—engineered for rapid thermal response, minimal oxidation at elevated temperatures, and efficient conductive heat distribution;
• Dual safety architecture: independent mechanical over-temperature cut-off and digital limit controller compliant with IEC 61000-6-2 EMC standards.

Sample Compatibility & Compliance

The GZF-6050CL accommodates a broad spectrum of sample formats—including powders, granules, thin-film substrates, ceramic precursors, metal oxide catalysts, pharmaceutical intermediates, and glassware—without particle displacement or surface oxidation. Its oxygen-free operation meets critical requirements for ASTM E145-22 (Standard Specification for Gravity-Convection and Forced-Ventilation Ovens) and ISO 17025:2017 clause 6.4.3 regarding environmental control during thermal treatment. When configured with optional inert gas inlet (N₂ or Ar), the unit supports processes aligned with USP Sterilization and FDA 21 CFR Part 11–compliant data integrity protocols when paired with validated software packages. The chamber geometry and shelf layout comply with GLP/GMP documentation needs for batch traceability and process repeatability.

Software & Data Management

Standard firmware includes timestamped cycle logs (start time, target temperature, vacuum level, duration, alarm events) stored in non-volatile memory. Optional RS485 Modbus RTU or USB-C interface enables integration into laboratory information management systems (LIMS) or SCADA platforms. With the programmable controller add-on, users define up to 30 segments per program—including heating rate (°C/min), dwell time, vacuum hold steps, and automatic inert gas purging sequences. All data exports as CSV for audit-ready reporting. Firmware supports password-protected user roles (Operator, Technician, Administrator) and maintains an immutable audit trail meeting ALCOA+ principles for regulated environments.

Applications

• Thermal stabilization of battery cathode materials (e.g., LiCoO₂, NMC) prior to sintering;
• Residual solvent removal from polymer electrolytes and OLED precursor films;
• Drying of hygroscopic reagents (e.g., anhydrous MgSO₄, P₂O₅) without hydrolytic degradation;
• Pre-sterilization conditioning of surgical instruments and labware under nitrogen blanket;
• Controlled pyrolysis of organic frameworks (MOFs/COFs) under dynamic vacuum profiles;
• Moisture analysis of construction materials (cement, gypsum) per ASTM C496 procedures;
• Accelerated aging studies of encapsulated electronic components under low-humidity, high-temperature stress.

FAQ

What vacuum level can the GZF-6050CL achieve, and is a vacuum pump included?
The chamber achieves ≤133 Pa using the standard 2 L/s vacuum pump (optional accessory); higher pumping speeds (e.g., 4 L/s) reduce evacuation time and improve stability for large-volume or high-outgassing loads.
Can the oven operate continuously at 600 °C?
Yes—rated for continuous duty at maximum temperature, provided ambient conditions remain within 15–35 °C and relative humidity ≤80% RH, non-condensing.
Is the temperature calibration traceable to national standards?
Factory calibration is performed using NIST-traceable Pt100 reference sensors; certificate of conformance is supplied. Field recalibration kits and third-party validation services are available upon request.
Does the unit support inert gas purging during operation?
Yes—optional inert gas inlet valve and mass flow controller enable automated nitrogen or argon purging before, during, or after vacuum cycles.
How many shelves are included, and what is their load capacity?
Three 304 stainless steel shelves are standard, each rated for 15 kg distributed load at 600 °C; additional shelves and reinforced carriers are available as accessories.
