Labonce Labonce-6090VC High-Precision Vacuum Drying Oven with Digital Vacuum Display

Overview

The Labonce Labonce-6090VC High-Precision Vacuum Drying Oven is an engineered solution for moisture-sensitive, heat-labile, or oxidation-prone sample processing in research laboratories, quality control environments, and small-scale production settings. Operating on the principle of reduced-pressure thermal drying, it lowers the boiling point of solvents and water—enabling effective dehydration at significantly lower temperatures than conventional convection ovens. This minimizes thermal degradation, prevents oxidation, and preserves structural integrity of polymers, pharmaceutical actives, biological extracts, and nanomaterials. The system integrates a built-in vacuum pump and employs a calibrated silicon piezoresistive pressure sensor for real-time, digital vacuum monitoring—eliminating analog gauges and associated parallax or calibration drift errors. Designed for ISO/IEC 17025-compliant workflows, its architecture supports traceable, repeatable drying protocols under controlled environmental conditions.

Key Features

• Touchscreen programmable controller with intuitive HMI interface, supporting up to 99-step multi-segment temperature and vacuum profiles
• High-resolution temperature control: 0.1 °C setpoint resolution with ±1 °C uniformity across the chamber volume (per ASTM E2207)
• Digital vacuum feedback loop using a factory-calibrated silicon piezoresistive sensor, delivering ±1% full-scale accuracy from atmospheric pressure down to ≤10 Pa
• Programmable vacuum cycling: users define upper/lower vacuum thresholds and number of cycles to automate degassing–repressurization sequences for volatile removal or solvent exchange
• Stainless steel 304 interior chamber (450×450×450 mm) with double-layer insulated door and silicone gasket for long-term vacuum integrity
• Integrated oil-lubricated rotary vane vacuum pump (ultimate vacuum ≤5 Pa), mounted externally for service accessibility and thermal isolation
• Two independently adjustable, load-bearing stainless steel shelves with reinforced support brackets—rated for uniform 15 kg per shelf

Sample Compatibility & Compliance

The Labonce-6090VC accommodates a broad range of sample formats—including glass Petri dishes, aluminum weighing boats, stainless steel trays, and custom fixtures—without compromising vacuum seal integrity. Its inert chamber surface and absence of air circulation prevent cross-contamination and particle generation, making it suitable for GLP and GMP-aligned applications such as residual solvent analysis (per USP ), active pharmaceutical ingredient (API) drying, and battery electrode material conditioning. The unit complies with IEC 61010-1:2010 for electrical safety and meets CE marking requirements for laboratory equipment. Vacuum and temperature logging data are timestamped and exportable in CSV format—supporting audit readiness for FDA 21 CFR Part 11–governed environments when paired with validated software configurations.

Software & Data Management

The embedded controller records real-time temperature and vacuum values at user-defined intervals (1–600 seconds), storing up to 10,000 data points internally. Data export is performed via USB 2.0 port to standard FAT32-formatted drives; no proprietary drivers or cloud dependencies are required. Optional RS485 Modbus RTU interface enables integration into centralized lab information management systems (LIMS) or SCADA platforms for remote monitoring and alarm notification. All parameter changes, setpoint adjustments, and cycle completions are logged with operator ID (if enabled), date/time stamp, and event type—fulfilling basic electronic record requirements per ALCOA+ principles.

Applications

• Drying of hygroscopic powders (e.g., lithium-ion cathode materials, metal-organic frameworks) without agglomeration or phase transition
• Removal of low-boiling solvents (acetone, ethanol, dichloromethane) from coated films and thin-film samples prior to SEM or XRD analysis
• Stabilization of enzyme preparations and lyophilized biologics where oxidative stress must be minimized
• Pre-conditioning of desiccants, silica gels, and molecular sieves for gravimetric moisture calibration
• Accelerated aging studies requiring controlled low-humidity, elevated-temperature exposure per IPC-TM-650 2.6.25

FAQ

Does the Labonce-6090VC include a vacuum pump?
Yes—the unit ships with a factory-integrated, maintenance-optimized rotary vane vacuum pump rated for continuous operation and capable of achieving ≤5 Pa ultimate vacuum.
Can vacuum and temperature be controlled simultaneously during a single program?
Yes—users may define synchronized time-based ramps for both parameters, including dwell periods at specific vacuum levels and temperatures.
Is the chamber volume verified per ISO 27874?
Chamber internal dimensions are measured and certified during final QA; volumetric capacity (90 L) is calculated geometrically and confirmed via displacement test per internal procedure QCP-VD-003.
What materials are used for seals and gaskets?
The door sealing system utilizes high-temperature silicone rubber (rated to 250 °C), compliant with FDA 21 CFR 177.2600 for incidental food contact.
How often does the vacuum sensor require recalibration?
Labonce recommends annual verification against a NIST-traceable reference transducer; field calibration is not user-serviceable but can be performed by authorized service centers.
