Overview
The Labonce DV-6210VC is a high-precision vacuum drying oven engineered for laboratories and production environments requiring controlled low-pressure thermal processing. It operates on the principle of reducing ambient pressure within a sealed chamber to lower the boiling point of volatile components—enabling gentle, uniform drying of heat-sensitive, hygroscopic, or oxidation-prone materials without thermal degradation. Unlike conventional convection ovens, this system eliminates convective heat transfer limitations and prevents surface hardening or crust formation by maintaining consistent vapor-phase mass transfer across the entire sample volume. Designed for reproducible process validation, the DV-6210VC integrates a calibrated silicon piezoresistive pressure sensor for real-time digital vacuum monitoring and closed-loop vacuum regulation—supporting both static vacuum hold and programmable multi-cycle vacuum-purge-dry sequences.
Key Features
- Touchscreen HMI controller with intuitive graphical interface, supporting up to 99-step programmable temperature/vacuum profiles and built-in timer functionality for unattended operation.
- Temperature control precision of ±1 °C (uniformity) and 0.1 °C resolution across the full operating range (RT+20 °C to 200 °C), verified per ASTM E2203 for laboratory oven qualification.
- Digital vacuum display with ±1% full-scale accuracy, enabling traceable pressure documentation critical for GLP/GMP-compliant workflows.
- Three independently controllable stainless-steel shelves with individual heating elements—allowing simultaneous processing of samples requiring distinct thermal profiles within a single chamber.
- Integrated oil-lubricated rotary vane vacuum pump (rated ultimate vacuum ≤5 Pa), pre-installed and factory-aligned to minimize installation complexity and leak-path variables.
- Double-layer insulated chamber with silicone-gasketed door and reinforced tempered glass viewport for visual process monitoring under vacuum conditions.
Sample Compatibility & Compliance
The DV-6210VC accommodates a broad spectrum of sample types including pharmaceutical powders (e.g., lyophilized APIs), polymer precursors, ceramic green bodies, moisture-sensitive electronic components, and biological tissue specimens. Its inert stainless-steel interior (304 grade) resists corrosion from organic solvents and acidic vapors. The system meets structural and safety requirements outlined in IEC 61010-1 (Electrical Safety for Laboratory Equipment) and complies with ISO 554:2022 for standardized conditioning environments. Vacuum and temperature data logging supports audit readiness for FDA 21 CFR Part 11 when paired with validated third-party software; all control parameters are timestamped and non-erasable in internal memory.
Software & Data Management
Data acquisition is managed via embedded firmware with RS485 Modbus RTU and optional Ethernet (TCP/IP) connectivity. Real-time vacuum and temperature values are logged at user-defined intervals (1 s to 60 min) and exportable as CSV or Excel-compatible files. The controller stores ≥10,000 data points per session with automatic rollover. Optional Labonce DataBridge™ software enables remote monitoring, alarm notification via email/SMS, and generation of IQ/OQ/PQ protocol templates aligned with USP Analytical Instrument Qualification guidelines.
Applications
- Residual solvent removal from active pharmaceutical ingredients (APIs) prior to tablet compression—ensuring compliance with ICH Q3C limits.
- Drying of nanomaterial dispersions without agglomeration, preserving primary particle size distribution measured by DLS or TEM.
- Moisture content determination in accordance with AOAC 950.46 and ASTM D2298 for quality control of adhesives and composites.
- Pre-treatment of MEMS devices and optical coatings to eliminate outgassing during subsequent vacuum deposition steps.
- Accelerated aging studies of battery electrode slurries under controlled humidity-vacuum cycles per UL 1642 Annex A.
FAQ
Does the DV-6210VC support external vacuum gauge calibration verification?
Yes—the system provides a dedicated ¼” NPT vacuum port for connecting certified reference gauges, and the controller allows manual offset adjustment within ±5% of reading to accommodate field recalibration.
Can the vacuum pump be bypassed for use with an external high-vacuum system?
Yes—via the rear-mounted isolation valve and auxiliary vacuum inlet port; the internal pump can be fully decoupled while retaining digital pressure feedback from the integrated sensor.
Is the temperature uniformity specification validated at vacuum or atmospheric pressure?
Uniformity is characterized at both atmospheric and 10 Pa vacuum conditions per ISO 15504-2 Annex B, confirming minimal convective perturbation under low-pressure operation.
What is the maximum allowable load weight per shelf?
Each shelf is rated for 15 kg distributed load; total chamber loading must not exceed 45 kg to maintain thermal stability and vacuum integrity.
Are spare vacuum seals and gasket kits available through Labonce’s global distribution network?
Yes—standardized silicone fluoroelastomer (FFKM) door gaskets and chamber O-rings are stocked in North America, EU, and APAC regional warehouses with 48-hour dispatch for registered customers.
