Overview
The BINDER VD23 Vacuum Drying Oven is a precision-engineered laboratory instrument designed for gentle, solvent-free drying, degassing, and moisture removal under reduced pressure. Based on the fundamental principle of lowering the boiling point of volatile substances via vacuum application—thereby enabling thermal treatment at significantly lower temperatures—the VD23 eliminates oxidation, thermal degradation, and cross-contamination risks common in atmospheric ovens. Its robust stainless-steel chamber (AISI 304), combined with direct conductive heating and high-stability PID temperature control, ensures reproducible thermal conditions essential for pharmaceutical stability studies, polymer curing, powder metallurgy pre-treatment, and analytical sample preparation. Certified to DIN EN 61000-6-3 (EMC) and DIN EN 61000-6-2 (immunity), the VD23 meets stringent requirements for integration into GLP-compliant laboratories and regulated R&D environments.
Key Features
- Stable vacuum operation down to ≤10 mbar (absolute), compatible with external vacuum pumps (e.g., diaphragm or oil-sealed types) via integrated G1/4″ ISO-KF port
- Precision temperature control with ±0.1 K fluctuation at 100 °C and ±1 K uniformity across the entire 24 L chamber volume
- Direct conductive heating system minimizes thermal gradients and eliminates hot-air convection artifacts—critical for heat-sensitive biological matrices and nanomaterials
- Intuitive 4.3″ TFT color touchscreen interface with multilevel user access (operator, supervisor, administrator), password protection, and configurable alarm thresholds
- Integrated overtemperature safety cut-off (independent mechanical thermostat) and door-open detection with automatic heating interruption
- Optional data logging capability (via USB or Ethernet) compliant with FDA 21 CFR Part 11 when paired with BINDER’s optional software suite
Sample Compatibility & Compliance
The VD23 accommodates standard laboratory glassware (e.g., weighing dishes, Petri dishes, crucibles) and custom fixtures up to 68 kg total load (including shelves). Its 285 × 285 × 295 mm internal dimensions support multi-level sample staging using up to four adjustable stainless-steel shelves (standard configuration: one shelf included). The oven complies with key international standards including IEC 61010-1 (safety of laboratory equipment), ISO 17025 (for calibration traceability), and supports validation protocols aligned with ASTM E2875 (Standard Guide for Validation of Vacuum Ovens) and USP (Analytical Procedure Validation). All materials contacting the chamber interior meet USP Class VI biocompatibility requirements.
Software & Data Management
The VD23 supports optional BINDER LabWorldSoft® software for remote monitoring, recipe management, and audit-trail generation. When configured with Ethernet connectivity and enabled security settings, the system provides electronic signatures, user activity logs, and immutable data export (CSV, PDF) — fulfilling core requirements of 21 CFR Part 11 for electronic records and signatures. Real-time process visualization includes vacuum level, chamber temperature, setpoint deviation, and elapsed time. Data integrity is preserved through cyclic memory buffering and automatic backup upon power interruption.
Applications
- Pharmaceutical: Residual solvent removal from APIs and excipients prior to lyophilization or tablet compression
- Materials Science: Degassing of composite resins, ceramic green bodies, and battery electrode slurries
- Environmental Testing: Moisture content determination in soils, sediments, and sludges per ISO 11465
- Electronics: Outgassing of PCB substrates and encapsulation compounds to prevent delamination during reflow
- Academic Research: Controlled dehydration of hydrogels, MOFs, and aerogel precursors without structural collapse
FAQ
What vacuum level can the VD23 achieve without an external pump?
The VD23 does not include an integrated vacuum pump; it requires connection to an external vacuum source. Typical ultimate pressures range from 1–10 mbar depending on pump type and system leak rate.
Is the chamber inert-gas compatible?
Yes—the VD23 can be optionally fitted with a gas inlet valve (order code: VD23-GAS) for nitrogen or argon purging prior to vacuum draw, supporting oxygen-sensitive processes.
Can temperature and vacuum profiles be programmed simultaneously?
No—vacuum level is manually controlled via external pump regulation; however, temperature ramps and holds are fully programmable (up to 10 segments) and logged synchronously with vacuum readings if an external sensor is connected.
Does the VD23 support IQ/OQ documentation?
Yes—BINDER provides factory-issued IQ/OQ templates and on-site qualification support services, aligned with ISO 9001 and GMP Annex 15 guidelines.
What is the recommended maintenance interval for the door seal?
The silicone door gasket should be inspected quarterly and replaced every 24 months or after 500 vacuum cycles, whichever occurs first, to maintain leak-tight performance.
