Titan VD-R6 Rotary Vacuum Dryer

Overview

The Titan VD-R6 Rotary Vacuum Dryer is a compact, benchtop-scale vacuum drying system engineered for controlled solvent removal, moisture reduction, and thermal-sensitive sample stabilization under reduced pressure. Unlike conventional ovens, the VD-R6 employs a combination of rotary motion and regulated vacuum—typically operating in the range of 1–100 mbar—to lower the boiling point of solvents and accelerate evaporation while minimizing thermal degradation. Its sealed chamber, integrated vacuum interface (KF16 or ISO-KF standard), and precision-adjustable rotation speed (0–60 rpm) enable uniform heat transfer across flask surfaces and prevent bumping or splashing during volatile removal. Designed for laboratories with limited floor space but high reproducibility requirements, the VD-R6 supports both batch and sequential drying workflows without requiring external chill traps or oil-free vacuum pumps (though compatibility with diaphragm and scroll-type pumps is verified).

Key Features

• Stainless steel vacuum chamber with borosilicate glass viewing port and reinforced silicone O-ring sealing for long-term leak integrity
• Stepless DC motor drive enabling precise rotational control (0–60 rpm) with digital feedback and overload protection
• Integrated analog vacuum gauge (0–1000 mbar range) with optional digital pressure sensor upgrade (±0.5% FS accuracy)
• PTC-heated aluminum heating mantle with PID temperature regulation (ambient to +150 °C, ±0.5 °C stability at setpoint)
• Quick-release clamping system for standard 14/20 and 24/29 ground-glass joints; accommodates up to 500 mL round-bottom flasks
• CE-compliant electrical architecture with thermal cutoff, motor stall detection, and emergency stop circuitry

Sample Compatibility & Compliance

The VD-R6 is compatible with a wide range of organic solvents (e.g., acetone, ethanol, ethyl acetate, dichloromethane), aqueous solutions, polymer precursors, and pharmaceutical intermediates. It is routinely deployed in QC labs handling USP sterility test residuals, ISO 17025-accredited material stability studies, and GLP-regulated extractables/leachables workflows. While the unit itself does not carry FDA 21 CFR Part 11 certification (as it is a standalone hardware device without audit-trail software), its mechanical design and documentation package support integration into Part 11–compliant environments when paired with validated LIMS or ELN systems. All wetted parts meet ASTM F2136-22 criteria for extractable residue testing in pharmaceutical contact materials.

Software & Data Management

The base VD-R6 operates via front-panel push-button controls with LED indicators for vacuum status, temperature, and rotation. For traceable operation, an optional RS-485/Modbus RTU interface enables connection to SCADA or LabVIEW-based supervisory systems. Logged parameters—including real-time pressure, setpoint temperature, actual temperature, and rotation speed—can be timestamped and exported as CSV files via USB host port (firmware v2.3+). Audit trail functionality (user login, parameter change history, session timestamps) is available through the Titan LabLink™ companion module, which complies with ALCOA+ data integrity principles and supports electronic signatures per Annex 11 requirements.

Applications

• Concentration of natural product extracts prior to HPLC analysis
• Drying of lyophilized protein formulations under inert gas backfill (N₂ or Ar)
• Removal of residual solvents from API batches per ICH Q3C guidelines
• Preparation of thin-film samples for SEM/TEM imaging without crystallization artifacts
• Stabilization of hygroscopic reference standards in metrology labs (ISO/IEC 17025 Clause 7.7)
• Accelerated aging studies of adhesives and coatings under controlled humidity/vacuum cycling

FAQ

What vacuum level can the VD-R6 achieve with a standard diaphragm pump?
When paired with a certified oil-free diaphragm pump (e.g., KNF NMP 830 series), the VD-R6 consistently reaches ≤5 mbar at room temperature with an empty chamber. Actual performance depends on chamber load, solvent vapor pressure, and ambient temperature.

Is the heating mantle compatible with corrosive solvents like HF or fuming nitric acid?
No. The aluminum heating mantle and stainless-steel chamber are not resistant to hydrofluoric acid, halogenated acids, or strong oxidizers. Use only with solvents listed in the Titan Chemical Compatibility Matrix (v4.1), accessible via technical support portal.

Can the VD-R6 be operated under nitrogen purge?
Yes. A dedicated gas inlet valve (optional accessory) allows continuous inert gas flow (0.1–2 L/min) during vacuum cycles to prevent oxidation or hydrolysis of air-sensitive compounds.

Does Titan provide IQ/OQ documentation for GMP environments?
Yes. Factory-verified Installation Qualification (IQ) and Operational Qualification (OQ) protocols—including calibration certificates for temperature and pressure sensors—are available upon request and align with ASTM E2500-13 and EU GMP Annex 15 expectations.
