BOXUN DZF-6020MBE & DZF-6050MBE Microprocessor-Controlled Vacuum Drying Oven

Overview

The BOXUN DZF-6020MBE and DZF-6050MBE are microprocessor-controlled vacuum drying ovens engineered for precise, low-oxidation thermal processing of heat-sensitive, hygroscopic, or chemically unstable samples. Operating under reduced pressure (≤133 Pa), these ovens lower the boiling point of solvents and moisture, enabling effective dehydration at significantly lower temperatures than atmospheric drying—thereby minimizing thermal degradation, oxidation, and structural alteration. Designed for routine use in QC laboratories, R&D facilities, and academic research environments, they comply with the national standard GB/T 29251–2012 for vacuum drying equipment performance and safety requirements. Their robust stainless steel (SUS304) chamber construction, double-layer tempered glass observation door, and fully sealed silicone gasket ensure long-term vacuum integrity and operator safety during extended cycles.

Key Features

• Microprocessor-based PID temperature control system with real-time digital display (dual LED screens), offering intuitive parameter setting via tactile membrane keys.
• Programmable timer (0–999 minutes) with auto-shutdown and power-failure recovery function—retains set values and operational status after unexpected interruption.
• Chamber geometry optimized for uniform airflow and thermal distribution: rectangular workspace with rounded internal corners for easy cleaning and residue-free maintenance.
• Dual-layer tempered and bulletproof glass door provides clear visual monitoring without compromising vacuum seal integrity or operator safety.
• Adjustable door compression mechanism ensures consistent sealing force across the full perimeter, supporting stable vacuum maintenance over prolonged operation.
• Sheathed heating elements integrated with forced air circulation deliver rapid thermal response and improved temperature homogeneity (±1°C) throughout the chamber volume.
• Front-panel alarm system triggers audible/visual alerts upon temperature overshoot or sensor failure, supporting GLP-aligned procedural documentation.

Sample Compatibility & Compliance

These vacuum ovens accommodate a broad range of sample formats—including Petri dishes, weighing boats, glass desiccators, ampoules, and custom trays—without requiring modification to standard lab workflows. They are routinely deployed in applications governed by ISO 17025-accredited testing protocols, particularly where moisture content determination (e.g., ASTM D2298, USP <921>) or residual solvent removal (per ICH Q5C) must be performed under inert or oxygen-limited conditions. The SUS304 chamber meets corrosion resistance requirements for exposure to organic solvents, weak acids, and saline solutions. While not certified to FDA 21 CFR Part 11 out-of-the-box, audit-ready operation is supported through manual logbook entries and timestamped parameter records—facilitating GMP and GLP compliance when integrated into documented quality systems.

Software & Data Management

The DZF-6020MBE and DZF-6050MBE operate as standalone instruments with embedded firmware; no external software or PC connectivity is required for basic operation. All critical parameters—including setpoint temperature, elapsed time, vacuum status indicator, and alarm history—are displayed locally on dual high-brightness LED modules. For regulated environments, users may integrate optional RS-232 or USB data logging modules (sold separately) to export timestamped temperature and timer logs to compliant LIMS or ELN platforms. Firmware supports user-defined calibration offsets (±5°C range) to align with traceable NIST-certified reference thermometers, ensuring metrological continuity across instrument lifecycles.

Applications

• Moisture analysis of pharmaceutical excipients, active ingredients, and lyophilized formulations prior to packaging.
• Drying of biological tissues, enzyme preparations, and antibody-conjugated nanoparticles without denaturation.
• Removal of residual solvents from polymer films, thin-film coatings, and printed electronics substrates.
• Pre-treatment of silica gel, molecular sieves, and other desiccants in analytical chemistry labs.
• Sterilization and decontamination of glassware and reusable lab components under vacuum-assisted thermal exposure.
• Accelerated aging studies of battery electrode materials and composite resins under controlled low-humidity thermal stress.

FAQ

What is the maximum achievable vacuum level, and how is it measured?
The oven achieves ≤133 Pa (1 Torr) using an integrated mechanical vacuum gauge calibrated per GB/T 29251–2012. Actual performance depends on chamber load, ambient humidity, and pump compatibility.
Can these models be used for inert gas purging?
No—these units are designed exclusively for vacuum operation. Inert gas backfilling requires optional retrofitting with gas inlet valves and pressure regulation hardware, not included in standard configuration.
Is the temperature sensor PT100-certified and field-replaceable?
The unit employs a Class B platinum RTD sensor mounted in the chamber wall. Calibration verification is possible using external reference probes; replacement requires factory service to maintain traceability.
Do the models support continuous operation at 250°C under vacuum?
Yes—both models are rated for continuous operation at their full temperature range (ambient +5°C to 250°C) under vacuum, provided ambient cooling conditions remain within 5–40°C and ventilation clearance is maintained per installation guidelines.
Are spare parts such as door gaskets and trays available internationally?
Original equipment manufacturer (OEM) gaskets, shelves, and chamber liners are stocked globally through authorized BOXUN distribution partners and carry 24-month shelf-life certification for sterile applications.
