Shanghai Yiheng DZF-6030A Vacuum Drying Oven

Overview

The Shanghai Yiheng DZF-6030A Vacuum Drying Oven is an engineered solution for thermal processing under reduced-pressure conditions, designed specifically for laboratories requiring precise moisture removal, solvent recovery, or oxygen-sensitive sample handling. Operating on the principle of vacuum-assisted thermal desorption, this unit lowers the boiling point of volatile components—enabling drying at significantly lower temperatures than atmospheric ovens. This minimizes thermal degradation of heat-labile compounds (e.g., pharmaceutical actives, polymer precursors, biological extracts) while preventing oxidation and maintaining chemical integrity. Its robust stainless-steel chamber, integrated microprocessor-based temperature controller, and sealed double-glass door provide stable, repeatable operation across a wide working range—from ambient +10°C up to 200°C—making it suitable for routine QC testing, R&D material stabilization, and pre-analytical sample preparation in compliance with ISO 17025 and GLP environments.

Key Features

• Stainless-steel interior chamber (320 × 320 × 300 mm) with seamless welds and electropolished finish—resistant to corrosion, easy to clean, and compatible with mild solvents and acidic vapors.
• Microprocessor-controlled PID temperature regulation with 0.1°C resolution and ±1°C uniformity across the chamber volume—ensuring traceable, reproducible thermal profiles.
• Double-layer tempered glass observation door with adjustable compression mechanism and molded silicone door seal—maintains vacuum integrity down to 133 Pa without leakage under continuous operation.
• Efficient 400 W resistive heating system with optimized heater placement—reduces average ramp time by over 50% compared to conventional vacuum ovens of similar capacity.
• Compact footprint (630 × 510 × 490 mm) designed for benchtop integration in space-constrained analytical labs, cleanrooms, or quality control suites.
• Single removable stainless-steel shelf (standard configuration), load-rated for uniform weight distribution; optional multi-shelf kits available for scalable throughput.

Sample Compatibility & Compliance

The DZF-6030A accommodates a broad spectrum of sample formats—including Petri dishes, weighing boats, glass vials, aluminum pans, and custom trays—without compromising vacuum stability or thermal homogeneity. It supports inert-atmosphere drying when purged with nitrogen or argon prior to evacuation, fulfilling requirements for ASTM D2240 (polymer hardness conditioning), USP (sterile product drying), and ISO 5725 (precision of measurement methods). While not certified to IEC 61010-1 out-of-the-box, its electrical architecture complies with Class I protection principles, and all safety interlocks (door-open cutoff, overtemperature shutdown) meet EN 60519-2 standards for industrial heating equipment. Documentation packages—including factory calibration reports and material certificates of conformance—are provided upon request to support internal audit trails.

Software & Data Management

The DZF-6030A operates via a standalone front-panel interface with real-time display of setpoint, actual temperature, elapsed time, and vacuum status (via analog gauge). For laboratories requiring electronic recordkeeping, optional RS-485 communication enables integration with LabVantage, Empower, or custom SCADA systems using Modbus RTU protocol. When paired with validated data loggers (e.g., Omega OM-DAQPRO-5300), the oven supports 21 CFR Part 11-compliant audit trails—including user ID, timestamped parameter changes, and event-driven alarms—facilitating GMP-aligned process validation and change control documentation.

Applications

• Residual solvent removal from APIs and excipients prior to lyophilization or tablet compression.
• Drying of hygroscopic reference standards (e.g., potassium hydrogen phthalate, sodium chloride) per USP general chapter .
• Moisture content determination in polymers, ceramics, and composite materials per ISO 3747.
• Pre-treatment of electron microscopy specimens to prevent beam-induced artifacts during sputter coating.
• Stabilization of calibration weights and precision metrology artifacts in low-humidity, oxidation-free environments.
• Accelerated aging studies of packaging materials under controlled thermal-vacuum stress.

FAQ

What vacuum level can the DZF-6030A achieve, and how is it measured?
The chamber achieves a base pressure of ≤133 Pa (1 Torr) using a standard two-stage rotary vane pump (not included). Vacuum level is monitored visually via an analog Bourdon-tube gauge calibrated to IEC 60051 standards.
Is the temperature controller programmable for multi-step drying cycles?
No—the DZF-6030A features a single-setpoint controller. For multi-segment thermal profiles, external programmable controllers or PLC-integrated configurations are recommended.
Can the oven be used with flammable solvents?
Only after installation of explosion-proof modifications (e.g., ATEX-certified vacuum pump, intrinsically safe sensors) and strict adherence to NFPA 45 guidelines. Standard configuration is rated for non-flammable applications only.
Does the unit include vacuum pump and tubing?
No—vacuum pump, oil mist filter, and vacuum-rated silicone tubing must be selected and procured separately based on required ultimate pressure and chemical compatibility.
What maintenance intervals are recommended for long-term reliability?
Silicone door gasket inspection every 6 months; vacuum gauge calibration annually; heater continuity check during semi-annual preventive maintenance per manufacturer’s service bulletin SB-DZF-2023-01.
