Boxun DZF-6050MBE Microcomputer-Controlled Vacuum Drying Oven

Overview

The Boxun DZF-6050MBE is a microprocessor-controlled vacuum drying oven engineered for precise, reproducible thermal processing under reduced-pressure conditions. It operates on the fundamental principle that lowering ambient pressure reduces the boiling point of volatile solvents and moisture—enabling effective dehydration of thermally sensitive, oxidation-prone, or structurally complex samples without thermal degradation. Designed for routine use in academic laboratories, pharmaceutical QC/QA units, and industrial R&D facilities, this unit delivers stable temperature control across its full operating range (ambient +5°C to 250°C) with a documented temperature fluctuation of ±1°C. Its 53 L stainless steel chamber (SUS304) features a seamless, semi-rounded corner geometry to minimize contamination traps and facilitate cleaning—a critical requirement under GLP-compliant environments. The integrated BX-1 rotary vane vacuum pump achieves an ultimate pressure of ≤1.33 Pa, supporting rapid evacuation and maintaining process integrity during extended drying cycles.

Key Features

• Robust dual-layer construction: Cold-rolled steel outer shell with electrostatic epoxy coating; corrosion-resistant SUS304 stainless steel inner chamber
• Intelligent microcomputer PID temperature controller with dual LED display (setpoint & real-time chamber temperature), touch-sensitive keypad interface, and programmable timer (0–999 minutes)
• High-integrity sealing system: Molded silicone door gasket with fully adjustable door tension mechanism ensures sustained vacuum retention up to 133 Pa
• Enhanced visibility and safety: Tempered double-glazed observation window (impact-resistant) provides unobstructed monitoring without compromising vacuum integrity
• Fail-safe operational continuity: Power-loss memory function retains set parameters and resumes operation upon grid recovery—critical for unattended overnight runs
• Thermal efficiency optimization: Jacketed electric heating design ensures uniform heat distribution and minimizes thermal gradients across the chamber volume

Sample Compatibility & Compliance

The DZF-6050MBE accommodates diverse sample formats—including powders, granules, lyophilized biologicals, ceramic precursors, polymer films, and precision-machined components—without risk of particle displacement or surface oxidation. Its inert vacuum environment eliminates combustion hazards associated with oxygen-rich drying, satisfying OSHA and IEC 61010-1 safety requirements for laboratory electrical equipment. While not certified to ISO/IEC 17025 or FDA 21 CFR Part 11 out-of-the-box, the system supports audit-ready documentation when paired with validated external data loggers and electronic lab notebook (ELN) integration. Its chamber geometry and material selection comply with common sterilization validation protocols referenced in ISO 17665 (moist heat) and ISO 11137 (radiation), making it suitable for pre-sterilization conditioning of glassware and stainless steel tools.

Software & Data Management

This model operates via embedded firmware without proprietary PC software. All operational parameters—including target temperature, dwell time, vacuum activation sequence, and alarm thresholds—are configured directly through the front-panel interface. Real-time temperature data is continuously displayed; however, raw logging requires external recording via analog output (0–5 V or 4–20 mA, optional upgrade) or RS485 Modbus RTU interface (available on request). For regulated environments, users may integrate third-party compliant data acquisition systems that support 21 CFR Part 11 electronic signatures, audit trails, and user access controls. Firmware updates are performed manually using USB flash drives following manufacturer-provided procedures.

Applications

• Drying heat-labile pharmaceutical intermediates and active pharmaceutical ingredients (APIs) per ICH Q5C stability guidelines
• Removing residual solvents from synthesized nanomaterials and catalyst supports prior to BET surface area analysis
• Conditioning reference standards and calibration weights in metrology labs to eliminate hygroscopic drift
• Pre-treating composite substrates before SEM/EDS analysis to prevent charging artifacts
• Dehydrating soil and sediment samples for gravimetric moisture content determination (ASTM D2216)
• Post-cleaning drying of surgical instruments and microfluidic devices where residue-free surfaces are mandatory

FAQ

What vacuum level can the DZF-6050MBE achieve, and how is it measured?
The system achieves a base pressure of ≤133 Pa using the included BX-1 vacuum pump. Ultimate vacuum performance is verified with a calibrated Pirani gauge traceable to NIST standards.
Is the chamber volume verified per ISO 27934?
Chamber net volume (53 L) is calculated geometrically from internal dimensions (415 × 370 × 344 mm) and confirmed by water-fill calibration during factory acceptance testing.
Can the oven be used for nitrogen-purged drying?
Yes—by connecting an external inert gas supply to the dedicated purge port (optional accessory), users may perform controlled atmosphere drying at sub-atmospheric or positive pressure.
Does the unit support remote monitoring or Ethernet connectivity?
No native Ethernet or Wi-Fi capability is provided; however, RS485 Modbus RTU communication is available as a configurable option for SCADA integration.
What maintenance is required for the BX-1 vacuum pump?
The pump requires quarterly oil changes using specified vacuum pump oil (ISO VG 100 grade) and annual inspection of vanes and seals per manufacturer’s maintenance schedule.
