Shanghai Youyi GZF-6150CL Vertical High-Temperature Vacuum Drying Oven

Overview

The Shanghai Youyi GZF-6150CL is a vertically oriented, high-temperature vacuum drying oven engineered for precise thermal processing under reduced-pressure environments. Operating across a calibrated temperature range of RT+10°C to 600°C, it employs resistive heating elements integrated with a robust 304 stainless steel chamber to ensure structural integrity and corrosion resistance at elevated temperatures. The system achieves and maintains vacuum levels ≤133 Pa via an integrated or externally coupled vacuum pump—enabling suppression of oxidative degradation, lowering solvent boiling points, and eliminating convective disturbance of delicate samples. This architecture is fundamentally aligned with vacuum thermogravimetric principles, where mass loss kinetics are monitored under controlled thermal and pressure conditions—making the GZF-6150CL suitable not only for routine drying but also for pre-analytical sample conditioning in materials science, pharmaceutical stability studies, and advanced ceramic sintering protocols.

Key Features

• Microprocessor-controlled PID temperature regulation with auto-tuning capability and 0.1°C resolution for reproducible thermal profiles
• Independent over-temperature safety cutoff and dual-stage thermal monitoring compliant with IEC 61000-4-2/4-4 immunity standards
• 4.3-inch backlit LCD interface supporting multi-parameter real-time display (setpoint, actual temperature, vacuum level, elapsed time)
• Full-seal silicone gasket door with adjustable clamping mechanism ensuring long-term vacuum integrity up to 600°C
• Aluminum heat-distribution shelves fabricated via precision stamping—resistant to oxidation, optimized for thermal conductivity and minimal radiant loss
• Power-failure recovery function retaining all user-defined parameters and operational state upon re-energization
• Modular design accommodating optional accessories including programmable multi-segment controllers, automatic nitrogen purge modules, and digital vacuum regulators with pressure-hold functionality

Sample Compatibility & Compliance

The GZF-6150CL supports diverse sample formats—including powders, granules, thin-film coatings, porous ceramics, and moisture-sensitive APIs—without mechanical displacement or surface oxidation. Its inert atmosphere capability (via optional N₂ inlet valve and flow meter) aligns with USP and requirements for sterile preparation environments, while its thermal uniformity (±1°C) meets ASTM E2209–21 criteria for laboratory ovens used in validation studies. The 304 stainless steel chamber complies with ISO 8573-1 Class 4 purity standards when operated with oil-free vacuum pumps. For GLP/GMP-regulated workflows, the system supports audit-trail-ready data logging when paired with external compliant software platforms adhering to FDA 21 CFR Part 11 electronic record requirements.

Software & Data Management

While the standard unit operates via embedded firmware without proprietary PC software, it features RS485 communication ports (optional) enabling integration into centralized lab management systems (LIMS) or SCADA networks. When equipped with the optional multi-segment programmable controller, users can define up to 32 ramp-hold cycles with slope-limited transitions—critical for controlled pyrolysis or binder burnout processes. All temperature and vacuum events are timestamped internally; data export requires external USB or serial loggers. For regulated environments, third-party validated data acquisition solutions (e.g., LabVIEW-based DAQ or DeltaV-compatible modules) may be deployed to satisfy ALCOA+ data integrity principles.

Applications

• Drying of thermally labile compounds (e.g., enzyme formulations, nucleic acid derivatives) without denaturation
• Residual solvent removal from lithium-ion battery electrode slurries prior to calendaring
• Pre-sintering degassing of metal injection molding (MIM) feedstocks
• Moisture content determination per ISO 15512 and ASTM D2298 for polymer composites
• Accelerated aging of encapsulants and conformal coatings under inert gas blanket
• Preparation of anhydrous reagents and catalyst supports requiring oxygen-free calcination
• Dehydration of hydrogels and aerogel precursors with minimized shrinkage and cracking

FAQ

What vacuum level is achievable with the standard configuration?
The base system achieves ≤133 Pa using a compatible 2 L/s or 4 L/s rotary vane pump; higher vacuum performance (≤10 Pa) requires optional oil-free dry pumps and extended pump-down time.
Is the chamber pressure monitored digitally by default?
No—the standard model includes an analog vacuum gauge; digital vacuum readout with auto-pressure maintenance requires the optional digital vacuum control module.
Can this oven be used for inert-gas purging during heating cycles?
Yes—when fitted with the optional inert gas inlet valve and precision flow meter (0–10 L/min range), continuous N₂ or Ar purging is supported throughout the entire thermal cycle.
Does the unit comply with CE or UL safety directives?
The GZF-6150CL conforms to GB/T 5170.11–2017 (Chinese national standard for environmental testing equipment); CE marking requires site-specific risk assessment and EMC testing per EN 61000-6-3/6-4.
What maintenance intervals are recommended for long-term operation at 600°C?
Silicone door gaskets should be inspected quarterly; heating element resistance verified biannually; vacuum pump oil changed every 500 operating hours (for oil-lubricated units).
