Shanghai RightOne GZF-6500AL High-Temperature Vacuum Oven (400°C)

Overview

The Shanghai RightOne GZF-6500AL is a high-performance vertical high-temperature vacuum oven engineered for precise thermal processing under controlled low-pressure environments. Operating on the principle of vacuum-assisted thermal desorption, it eliminates convective heat transfer and suppresses oxidation by removing atmospheric oxygen and reducing the boiling points of volatile solvents and moisture. This enables safe, residue-free drying of thermally sensitive, hygroscopic, or oxidation-prone materials—including pharmaceutical intermediates, catalyst precursors, battery electrode slurries, ceramic green bodies, and polymer composites—without thermal degradation or surface migration. Its maximum operating temperature of 400°C, combined with stable vacuum maintenance at ≤133 Pa, supports applications ranging from solvent removal in nanomaterial synthesis to post-sintering degassing of advanced ceramics. The unit is constructed as an integrated system with built-in vacuum line interface, robust chamber sealing, and electric heating elements embedded in reinforced chamber walls for uniform thermal distribution.

Key Features

• Stainless steel working chamber (AISI 304) with seamless welds and electropolished interior for corrosion resistance and easy cleaning
• PID-controlled digital temperature regulation with 0.1°C resolution and ±1°C uniformity across full chamber volume
• Integrated 4.3-inch TFT LCD touchscreen interface supporting multi-segment programmable temperature profiles (optional upgrade)
• Intelligent power recovery function preserving setpoints and timer status after unexpected power interruption
• High-efficiency aluminum alloy heating plates with optimized thermal conductivity and long-term oxidative stability at elevated temperatures
• Custom-molded silicone door gasket ensuring consistent vacuum integrity over repeated thermal cycling
• Dual-stage safety architecture: independent mechanical overtemperature cut-off + electronic limit controller compliant with IEC 61000-4 immunity standards
• Modular vacuum port configuration compatible with standard KF-25/KF-40 flanges and optional inert gas purging (N₂/Ar)

Sample Compatibility & Compliance

The GZF-6500AL accommodates heterogeneous sample types including powders, granules, thin-film substrates, porous monoliths, and assembled microcomponents. Its large internal volume (430 L) and vertical chamber geometry facilitate stacking of multiple trays without airflow interference—critical for maintaining structural integrity of fragile aerogels or printed electronics. All wetted surfaces meet USP Class VI biocompatibility requirements. The system supports audit-ready operation per FDA 21 CFR Part 11 when paired with validated data logging software: electronic signatures, time-stamped event logs (door open/close, vacuum pump activation, temperature deviation alarms), and immutable record retention are fully implementable. It conforms to ISO 14644-1 Class 8 cleanroom-compatible construction practices and satisfies ASTM E2877-22 criteria for vacuum drying validation of hygroscopic active pharmaceutical ingredients (APIs).

Software & Data Management

Standard firmware includes real-time data acquisition at 1-second intervals, exportable via USB to CSV format. Optional RS485/Modbus RTU interface enables integration into centralized laboratory information management systems (LIMS) or SCADA platforms. With the programmable controller add-on, users define up to 32 temperature ramps and holds, each with associated vacuum pressure setpoints and dwell times. All operational parameters—including actual chamber temperature, vacuum level, elapsed time, and alarm history—are timestamped and stored locally for ≥12 months. Audit trail functionality meets GLP/GMP traceability mandates, recording operator ID, parameter changes, and calibration events with cryptographic hash verification.

Applications

• Drying of lithium-ion battery cathode/anode materials under inert atmosphere to prevent Li₂CO₃ formation
• Thermal conditioning of optical coatings and MEMS devices prior to hermetic packaging
• Removal of residual solvents from spin-coated perovskite precursor films
• Post-processing of metal-organic frameworks (MOFs) to preserve porosity and crystallinity
• Dehydration of biological tissue scaffolds without protein denaturation
• Outgassing of ultra-high vacuum (UHV) components prior to chamber installation
• Accelerated aging studies of encapsulants and conformal coatings per IPC-9701

FAQ

What vacuum pumps are recommended for optimal performance with the GZF-6500AL?
A two-stage rotary vane pump rated at ≥4 L/s pumping speed is advised for rapid evacuation to ≤133 Pa within ≤15 minutes. Oil-free scroll pumps may be used where hydrocarbon contamination must be avoided.
Can the chamber accommodate custom fixtures or internal instrumentation?
Yes—the 630 × 810 × 845 mm cavity allows mounting of thermocouple feedthroughs, quartz viewports (optional), or sample holders with external actuation ports.
Is the unit suitable for continuous operation at 400°C?
It is rated for sustained operation at 400°C; however, chamber load, vacuum integrity, and ambient cooling capacity must be validated per IEC 60068-2-2 for extended duty cycles.
How is temperature uniformity verified across the working volume?
Uniformity is confirmed using nine calibrated PT100 sensors placed at standardized locations (corners, center, mid-height) per ISO 17025-accredited validation protocol.
Does the system support automated inert gas backfilling?
When equipped with the optional inert gas inlet valve and mass flow controller, the unit executes programmable N₂/Ar purge sequences with pressure ramping and dwell control.
