Titan VD-C11 Benchtop Vacuum Desiccator Cabinet

Overview

The Titan VD-C11 is a compact, stainless-steel benchtop vacuum desiccator cabinet engineered for controlled moisture removal, solvent recovery, and inert-atmosphere sample storage in analytical laboratories, quality control environments, and R&D facilities. Unlike conventional desiccators relying solely on desiccant gels, the VD-C11 integrates a built-in vacuum pump interface, dual-stage pressure regulation, and hermetically sealed polycarbonate viewing window to enable active vacuum drying at pressures down to 10 mbar (absolute). Its operation follows fundamental principles of vapor pressure depression: under reduced pressure, the boiling point of residual solvents or adsorbed water decreases significantly—enabling gentle, low-temperature drying of thermally sensitive compounds such as pharmaceutical intermediates, polymer precursors, and hygroscopic reference standards without decomposition or oxidation.

Key Features

• Robust 304 stainless-steel chamber (350 × 350 × 300 mm internal dimensions) with electropolished interior for corrosion resistance and ease of cleaning
• Integrated vacuum port with ISO-KF25 flange compatibility—designed for connection to external diaphragm or scroll vacuum pumps (not included)
• Two-stage analog vacuum control: coarse venting valve + fine-tuning needle valve for precise pressure stabilization between 10–1000 mbar
• Optically clear, 12-mm-thick polycarbonate lid with silicone O-ring seal (IP65-rated) and integrated pressure relief valve (set at 1.2 bar overpressure)
• Removable, perforated stainless-steel sample trays (3-tier configuration) supporting uniform airflow and multi-sample parallel processing
• No internal heating elements—designed exclusively for ambient-temperature vacuum drying to eliminate thermal gradients and ensure batch consistency

Sample Compatibility & Compliance

The VD-C11 accommodates a wide range of solid and powder samples—including lyophilized biologics, metal-organic frameworks (MOFs), catalyst supports, ceramic green bodies, and crystalline APIs—without risk of thermal degradation. Chamber geometry and tray layout comply with ASTM D1711-22 (Standard Terminology Relating to Electrical Insulating Liquids and Gases) for desiccator-based moisture equilibrium testing. The unit meets CE marking requirements per Directive 2014/30/EU (EMC) and 2014/35/EU (LVD), and its material certifications include EN 10088-1 for stainless steel grade 304 and UL 94 V-0 for polycarbonate components. For GLP/GMP-regulated workflows, the absence of embedded electronics ensures full traceability of vacuum exposure time via external loggers compliant with FDA 21 CFR Part 11 when paired with validated pressure transducers.

Software & Data Management

The VD-C11 operates as a hardware-only platform with no onboard firmware or proprietary software—ensuring long-term interoperability and eliminating vendor lock-in. Users integrate it into existing laboratory data ecosystems via third-party vacuum monitoring systems (e.g., Pfeiffer TPG300 series, MKS Baratron 627B) connected through standard 0–10 V analog outputs or RS-485 Modbus RTU. All pressure logs, dwell times, and venting sequences are captured within enterprise LIMS or ELN platforms using configurable I/O modules. This architecture aligns with ISO/IEC 17025:2017 clause 7.7 (Ensuring validity of results) by enabling full audit trails of environmental conditions during drying cycles.

Applications

• Pretreatment of XRD and SEM samples to prevent surface hydration artifacts during structural characterization
• Stabilization of hygroscopic calibration standards (e.g., potassium hydrogen phthalate, sodium chloride) prior to gravimetric analysis per USP
• Storage of moisture-sensitive reagents (e.g., Grignard reagents, lithium aluminum hydride) under nitrogen-purged vacuum
• Drying of filter papers and membrane filters post-filtration in environmental water testing (EPA Method 1664)
• Conditioning of reference materials for certified reference material (CRM) producers accredited to ISO 17034

FAQ

Does the VD-C11 include a vacuum pump?
No—the VD-C11 is a vacuum chamber only. A compatible external pump must be selected based on required ultimate pressure and pumping speed (recommended: ≥1.5 m³/h at 10 mbar).

Can the chamber be purged with inert gas before evacuation?
Yes—via the dual-purpose inlet valve, users may introduce nitrogen or argon to displace oxygen prior to vacuum initiation, supporting anaerobic sample handling.

Is the polycarbonate lid resistant to common organic solvents?
It exhibits excellent resistance to alcohols, acetone, and chloroform but limited resistance to aromatic hydrocarbons (e.g., toluene) and strong bases; consult the Titan Chemical Compatibility Matrix (Rev. 4.2) for extended exposure guidelines.

What maintenance is required for long-term sealing integrity?
Silicone O-rings should be inspected quarterly and lubricated with Dow Corning High Vacuum Grease (HV-200); replacement is recommended every 18 months under daily use.
