AS ONE 1-066-21 Vacuum Desiccator Cabinet (240 mm Diameter Model)

Overview

The AS ONE 1-066-21 Vacuum Desiccator Cabinet (240 mm Diameter Model) is a precision-engineered, benchtop vacuum storage system designed for moisture-sensitive sample preservation, long-term desiccation, and inert-atmosphere handling in analytical, pharmaceutical, and materials science laboratories. Unlike conventional drying ovens or static desiccators, this unit operates on a controlled vacuum principle—removing ambient moisture and oxygen by reducing internal pressure to ≤133 Pa (1 mmHg), thereby suppressing hydrolysis, oxidation, and humidity-induced degradation of hygroscopic compounds, reference standards, calibration weights, thin-film substrates, and electronic components. Its all-PC construction eliminates metal corrosion risks while ensuring optical clarity for real-time visual monitoring without compromising structural integrity under repeated vacuum cycling. The unit is not heated; it functions as a passive, non-thermal vacuum desiccation chamber—making it suitable for temperature-sensitive materials where thermal stress must be avoided.

Key Features

• Lightweight yet impact-resistant polycarbonate (PC) body—engineered for high tensile strength and dimensional stability under vacuum load
• Lubricant-free vacuum sealing architecture: precision-machined O-ring grooves with NBR elastomer gaskets ensure repeatable, leak-tight closure without silicone oil contamination—a critical requirement for trace-level analytical workflows
• Optically transparent chamber enables continuous visual inspection of samples and desiccant condition without breaking vacuum
• Integrated vacuum port with standard Φ9 mm male metal connector for compatibility with AS ONE vacuum pumps (e.g., VP-100 series) and third-party diaphragm or scroll vacuum sources
• Compact footprint (245 mm diameter × 296 mm height) optimized for limited bench space in QC labs and R&D cleanrooms
• No internal heating elements—eliminates thermal gradients, condensation risks, and unintended sample decomposition during extended storage

Sample Compatibility & Compliance

This desiccator cabinet accommodates a wide range of sample formats including glass vials, aluminum weighing boats, ceramic crucibles, silicon wafers, polymer films, and pre-weighed analytical standards. Its inert PC housing and NBR sealing system are compatible with common desiccants (e.g., silica gel, phosphorus pentoxide, molecular sieves) and do not outgas volatile organics under vacuum—ensuring minimal background interference in gravimetric or spectroscopic applications. The design conforms to general laboratory safety guidelines per ISO 7218 and supports GLP-compliant documentation when used with calibrated vacuum gauges and logbook-based usage tracking. While not certified for explosion-proof operation, its non-sparking construction makes it appropriate for use with non-flammable desiccants in Class 10,000 cleanroom environments.

Software & Data Management

The AS ONE 1-066-21 is a manually operated, analog vacuum system with no embedded electronics or digital interface. Vacuum level verification requires an external analog or digital vacuum gauge (e.g., Pirani or capacitance manometer) connected via the standard Φ9 mm port. For regulated environments requiring audit trails—such as pharmaceutical QC labs operating under FDA 21 CFR Part 11 or ISO/IEC 17025—users are advised to integrate the unit into a documented vacuum process protocol, including gauge calibration records, desiccant replacement logs, and vacuum hold-time validation reports. AS ONE provides traceable calibration certificates for optional vacuum gauges sold separately.

Applications

• Precision weighing of hygroscopic reference standards (e.g., USP-grade chemicals, CRM materials) prior to dissolution or titration
• Storage of desiccated biological reagents, lyophilized enzymes, and nucleic acid pellets
• Conditioning of humidity-sensitive sensors, MEMS devices, and optical coatings prior to metrology
• Preparation of anhydrous reaction vessels and glassware for Schlenk-line or glovebox transfer
• Long-term archival of calibration weights, certified reference materials (CRMs), and metrology artifacts per ISO 17025 clause 6.4.7
• Moisture exclusion during crystal growth experiments and thin-film deposition staging

FAQ

Is the AS ONE 1-066-21 equipped with a built-in vacuum pump?

No. It requires an external vacuum source compatible with a Φ9 mm male connector.
Can this unit be used for drying wet samples?

It is not designed for active drying; it maintains low-humidity storage conditions. For solvent removal, a heated vacuum oven (e.g., AS ONE VDO-200 series) is recommended.
What is the maximum allowable vacuum level, and how is it verified?

The chamber sustains ≤133 Pa (1 mmHg) under static conditions. Verification requires an externally connected, calibrated vacuum gauge.
Does the polycarbonate body withstand repeated vacuum cycling over time?

Yes—AS ONE’s PC formulation is stress-relieved and vacuum-rated for ≥10,000 cycles at ≤133 Pa, with no measurable creep or seal fatigue under proper O-ring maintenance.
Is the unit compliant with FDA 21 CFR Part 11 requirements?

As a standalone mechanical device without electronic data capture, it does not fall under Part 11 scope—but its usage can be validated and documented within a compliant QMS framework.
