Shanghai Youyi GZF-6210A High-Temperature Vacuum Drying Oven

Overview

The Shanghai Youyi GZF-6210A is a high-temperature vacuum drying oven engineered for precision thermal processing under controlled low-pressure environments. It operates on the fundamental principle of vacuum-assisted thermal desorption—reducing ambient pressure to lower the boiling points of volatile components, thereby enabling rapid, gentle, and oxygen-free drying of thermally sensitive, oxidizable, or structurally complex samples. Unlike forced-air convection ovens, this system eliminates convective heat transfer and oxidative degradation by maintaining a sealed, inertable chamber capable of sustaining ≤133 Pa vacuum. Its maximum operating temperature of 400°C supports applications ranging from solvent removal in pharmaceutical intermediates to post-sintering degassing of ceramic powders and residual moisture elimination in hermetic electronic assemblies.

Key Features

• Microprocessor-based PID temperature control with programmable ramp-soak profiles, ensuring thermal stability within ±1°C across the full 400°C range and resolution of 0.1°C.
• Robust 304 stainless steel interior chamber (560 × 600 × 640 mm) and cold-rolled steel exterior with electrostatic powder coating for long-term corrosion resistance and thermal integrity.
• Integrated silicone door gasket with adjustable clamping mechanism guarantees repeatable vacuum seal performance and maintains ≤133 Pa ultimate vacuum without leakage drift.
• 4.3-inch LCD interface displaying real-time temperature, setpoint, elapsed time, and vacuum status—menu-driven navigation enables intuitive operation without technical training.
• Power-fail recovery function retains user-defined parameters and resumes operation upon power restoration, minimizing experimental interruption and data loss.
• Aluminum heating plates—formed via precision stamping and surface-treated for high-temperature oxidation resistance—provide uniform radiant heat distribution and reduced thermal inertia.
• Dual independent safety systems: mechanical over-temperature cutoff and digital limit controller compliant with IEC 61000-6-2 EMC immunity standards.

Sample Compatibility & Compliance

The GZF-6210A accommodates diverse sample formats including glass vials, crucibles, petri dishes, porous ceramics, metal sintered parts, polymer composites, and lyophilized biological matrices. Its oxygen-free environment prevents decomposition of peroxides, nitro compounds, and metal hydrides during thermal treatment—critical for ASTM E2074 (thermal stability testing) and USP packaging material evaluation. The chamber design conforms to ISO 14644-1 Class 8 cleanroom-compatible handling protocols when used with optional inert gas purging kits. All electrical components meet CE marking requirements under Directive 2014/30/EU (EMC) and 2014/35/EU (LVD), and the unit supports GLP-compliant audit trails when integrated with optional programmable controllers featuring 21 CFR Part 11–enabled software.

Software & Data Management

While the standard configuration features standalone microcontroller logic, optional upgrades include a 5-segment programmable temperature controller with USB data logging (up to 10,000 records), CSV export capability, and password-protected parameter editing. The system supports time-stamped event logging—including vacuum pump activation, nitrogen purge initiation, and temperature deviation alarms—for traceability in regulated QC/QA workflows. When paired with external vacuum gauges or mass flow controllers (e.g., Brooks 5850E), analog 4–20 mA outputs enable integration into SCADA or LIMS platforms for centralized monitoring and automated batch reporting.

Applications

• Residual solvent removal from API synthesis intermediates under inert atmosphere (ICH Q5C compliance support).
• Drying of nanomaterials (e.g., MOFs, graphene oxide dispersions) without aggregation or surface functional group loss.
• Post-processing of 3D-printed metal parts to eliminate trapped build chamber gases prior to HIP or heat treatment.
• Moisture conditioning and outgassing of optical substrates and vacuum chamber components for semiconductor tool qualification.
• Thermal aging studies of encapsulants and conformal coatings per MIL-STD-883 Method 1008.8.
• Pre-sterilization dehydration of surgical instruments where steam autoclaving is contraindicated.

FAQ

What vacuum level is achievable with the built-in system?
The GZF-6210A achieves ≤133 Pa using its integrated vacuum valve and compatible external pumps; actual performance depends on pump selection (e.g., 2 L/s or 4 L/s rotary vane units recommended).

Can the chamber be purged with nitrogen or argon?
Yes—optional inert gas inlet valves with calibrated flow meters (0–10 L/min range) are available for continuous or pulse-purge operation.

Is validation documentation provided for IQ/OQ protocols?
Factory calibration certificates for temperature and vacuum sensors are included; full 3Q documentation packages (including traceable thermocouple mapping reports) can be supplied upon request.

How many trays are included, and what is their load capacity?
Two adjustable 304 stainless steel trays are standard; each supports up to 15 kg uniformly distributed load at 400°C.

Does the unit comply with UL or CSA safety standards?
It meets CE requirements and is designed to IEC 61010-1:2010 for laboratory equipment; UL/CSA certification requires localized third-party assessment due to regional regulatory variance.
