WIGGENS WOV-65 Vacuum Drying Oven

Overview

The WIGGENS WOV-65 Vacuum Drying Oven is an engineered solution for low-temperature, solvent-sensitive drying and thermal stabilization of heat-labile samples in research laboratories, pharmaceutical QC environments, and materials science facilities. Operating on the principle of vacuum-assisted evaporation, the oven reduces ambient pressure inside the chamber—thereby lowering the boiling point of solvents—enabling efficient removal of moisture or organic volatiles without subjecting samples to thermally degrading temperatures. This physical principle is especially critical for applications involving polymers, active pharmaceutical ingredients (APIs), biological extracts, and nanomaterial precursors where thermal decomposition or oxidation must be avoided. The unit complies with general design requirements for Class II laboratory ovens per DIN 12880 and incorporates a robust stainless-steel interior (AISI 304), double-sealed spring-loaded tempered glass door, and independent vacuum and vent ports to ensure rapid evacuation and controlled repressurization.

Key Features

• PID-based microprocessor temperature controller with intuitive LED touchscreen interface and 0.1°C display resolution
• Three programmable temperature setpoints stored in non-volatile memory for repeatable workflow execution
• Jacket-type resistive heating system providing uniform thermal distribution across the chamber volume
• Dual-port configuration: separate Ø10 mm vacuum inlet and exhaust outlet to minimize cross-contamination and support integration with external vacuum pumps or gas purging systems
• Integrated over-temperature safety cutoff and automatic door-open alarm that halts heating and triggers audible/visual alerts
• RS232 serial interface enabling remote monitoring, data logging, and integration into centralized lab management systems (e.g., LabVantage, STARLIMS)
• Tempered glass observation window with high-visibility optical clarity and silicone gasket sealing rated for sustained operation at −0.1 MPa

Sample Compatibility & Compliance

The WOV-65 accommodates standard laboratory sample formats including Petri dishes, weighing boats, glass desiccators, and custom trays up to 400 mm wide. Its stainless-steel chamber resists corrosion from acidic vapors, chlorinated solvents, and aqueous residues—making it suitable for ASTM D2243 (polymer drying), USP (moisture content determination), and ISO 554 (standard atmospheres for conditioning). While not certified for explosion-proof use, the oven meets IEC 61010-1:2010 safety standards for electrical equipment used in laboratory environments. It supports GLP-compliant workflows through traceable temperature calibration (per ISO/IEC 17025 guidelines) and optional audit-trail-enabled software extensions.

Software & Data Management

The built-in RS232 port supports ASCII protocol communication for real-time parameter readout (actual temperature, setpoint, vacuum level, elapsed time) and command-driven control (start/stop, setpoint update, timer reset). When paired with WIGGENS’ optional PC-based control suite (v3.2+), users gain access to time-stamped CSV export, multi-curve graphing, deviation alarms, and electronic signature functionality aligned with FDA 21 CFR Part 11 requirements for regulated environments. All firmware updates are delivered via secure HTTPS download and validated using SHA-256 checksums.

Applications

• Drying of hygroscopic compounds prior to Karl Fischer titration or XRD analysis
• Removal of residual solvents from lyophilized formulations under inert gas backfill
• Thermal aging studies of elastomers and adhesives under controlled partial pressure
• Pre-conditioning of reference standards for gravimetric moisture analysis (ISO 15512)
• Stabilization of catalysts and MOFs after solvent exchange without structural collapse
• Low-oxygen annealing of thin-film semiconductor precursors

FAQ

What vacuum pump compatibility does the WOV-65 support?
The Ø10 mm vacuum port accepts standard KF-10 or ISO-KF flanged connections; recommended backing pumps include dual-stage rotary vane models with ultimate vacuum ≤5×10⁻² mbar.
Can the WOV-65 operate under inert gas purge?
Yes—users may introduce nitrogen or argon via the exhaust port while maintaining sub-atmospheric pressure; flow rate should be regulated externally to avoid chamber over-pressurization.
Is calibration documentation included with shipment?
A factory-issued temperature uniformity report (measured at three points per shelf level at 100°C and 200°C) is provided; NIST-traceable calibration certificates are available upon request at additional cost.
Does the unit meet electromagnetic compatibility (EMC) requirements for EU labs?
Yes—the WOV-65 conforms to EN 61326-1:2013 for laboratory equipment and carries CE marking under the EU Machinery Directive 2006/42/EC.
What maintenance intervals are recommended?
Silicone door gaskets should be inspected quarterly; vacuum hose fittings require tightening every six months; heating jacket insulation integrity should be verified annually by qualified service personnel.
