Yoyilab DZF-6210 Integrated Vacuum Drying Oven with Built-in Vacuum Pump

Overview

The Yoyilab DZF-6210 Integrated Vacuum Drying Oven is an engineered solution for controlled thermal processing under reduced-pressure environments. Based on the fundamental principle of lowering the boiling point of volatile components via vacuum application, this system enables gentle, oxygen-free drying of thermally sensitive, oxidation-prone, or compositionally complex samples—including pharmaceutical intermediates, polymer precursors, biological extracts, and ceramic slurries. Unlike conventional convection ovens, the DZF-6210 eliminates oxidative degradation and minimizes thermal stress by operating in a sealed stainless-steel chamber evacuated to ≤133 Pa, while maintaining precise temperature control from ambient +10°C up to 250°C. Its integrated 2 L/s rotary vane vacuum pump—housed within a dedicated lower cabinet—ensures rapid evacuation without external plumbing or footprint expansion, supporting reproducible process cycles in regulated laboratory and pilot-scale manufacturing settings.

Key Features

• Robust chamber construction: 304 stainless steel interior (electropolished finish) and cold-rolled steel exterior with epoxy powder coating for corrosion resistance and structural integrity.
• Precision temperature regulation: Microprocessor-based PID controller with 0.1°C resolution, ±1°C uniformity across the full working volume (560 × 600 × 640 mm), and auto-recovery function following power interruption.
• Optimized thermal architecture: Fixed aluminum shelving (special-stamped, oxidation-resistant) ensures rapid, even heat transfer and minimal thermal lag; internal heating elements eliminate hot/cold zones common in external-heated designs.
• Enhanced operational visibility and safety: Double-layer tempered glass door with silicone gasket seal, rated for continuous high-vacuum operation; inert gas purge port (optional) allows nitrogen or argon backfilling post-drying to prevent rehydration or oxidation during sample retrieval.
• User-centric interface: Large LCD display showing real-time temperature, setpoint, vacuum level (via analog gauge), and timer status; intuitive menu-driven navigation supports multi-step protocol setup without external software.
• Configurable sealing & vacuum integrity: Adjustable door-tightening mechanism and one-piece molded silicone door seal ensure long-term vacuum retention and compliance with ISO 554 (standard conditions for conditioning and testing).

Sample Compatibility & Compliance

The DZF-6210 accommodates a broad spectrum of sample formats: glass Petri dishes, weighing boats, crucibles, custom trays, and standard 1–4 shelf configurations (3 included). It supports moisture-sensitive APIs per ICH Q5C guidelines, lyophilization pre-drying steps compliant with USP , and residual solvent removal aligned with ASTM E2652–20. The stainless-steel chamber meets FDA-recommended material criteria for non-reactive contact surfaces, and its sealed design facilitates GLP/GMP audit readiness when paired with optional data logging and electronic signature-capable programmable controllers (21 CFR Part 11 compliant firmware available upon request).

Software & Data Management

While the base unit operates via embedded firmware with local parameter storage (retains settings after power loss), optional upgrades include a programmable multi-segment temperature controller with USB/RS485 output, enabling time-temperature-vacuum profile logging and export to CSV or Excel. All recorded datasets include timestamps, operator ID fields, and event annotations (e.g., “vacuum reached”, “door opened”), satisfying traceability requirements under ISO/IEC 17025 Clause 7.7 and EU Annex 11 for computerized system validation.

Applications

• Drying heat-labile enzymes, antibodies, and vaccine adjuvants without denaturation.
• Removing solvents from nanoparticle dispersions and thin-film coatings prior to characterization (XRD, SEM).
• Stabilizing hygroscopic reference standards for gravimetric analysis (ASTM E29, ISO 6329).
• Pre-conditioning catalysts and battery electrode materials under inert atmosphere to preserve surface reactivity.
• Accelerated aging studies of packaging polymers under controlled thermal-vacuum stress (ISO 11607-1).
• Dehydrating soil and sediment samples for elemental analysis (EPA Method 3010A, ASTM D2234).

FAQ

What vacuum level can the integrated pump achieve, and how is it monitored?
The built-in 2 L/s rotary vane pump reaches ≤133 Pa (1 Torr), verified using the front-panel analog vacuum gauge calibrated per ISO 2533. Digital readouts are available with optional electronic vacuum sensors.
Is the chamber suitable for use with corrosive vapors such as HCl or acetic acid?
Standard 304 stainless steel offers moderate resistance; for aggressive chemistries, we recommend electropolished 316L chamber lining (custom order) and chemical-resistant vacuum pump oil.
Can the DZF-6210 be validated for GMP production environments?
Yes—when equipped with IQ/OQ documentation packages, calibrated PT100 probes, and 21 CFR Part 11-compliant software, it supports qualification per ASTM E2500 and EU GMP Annex 15.
How many shelves are included, and are they removable?
Three fixed-position aluminum shelves are supplied; they are not user-removable due to integrated heating element routing but are optimized for load distribution and thermal homogeneity.
Does the unit support inert gas purging, and what fittings are required?
A threaded M12×1.0 inlet port is provided on the rear panel; the optional inert gas kit includes a precision needle valve, stainless steel tubing, and a 0–10 L/min rotameter calibrated for N₂ or Ar.
