AS ONE SP-BGKFN-P Desiccator Cabinet with Braking Casters (BG-FN Series)

Overview

The AS ONE SP-BGKFN-P is a precision-engineered, vacuum-compatible desiccator cabinet designed for long-term, low-humidity storage of moisture-sensitive laboratory materials—including hygroscopic standards, calibration reference substances, optical components, semiconductor wafers, and analytical reagents. Unlike conventional silica-gel or refrigerated desiccators, this unit employs solid polymer electrolyte membrane (SPEM) technology: a continuous electrochemical process that dissociates adsorbed water molecules into hydrogen and oxygen gases at the anode, expelling them directly from the chamber as dry gas—eliminating condensate formation, mechanical moving parts, and maintenance-dependent desiccant replacement. Its compact footprint and wall-adjacent installation capability stem from a patented hinge-free door mechanism and front-accessible service layout, making it suitable for constrained benchtop environments in QC labs, metrology centers, and R&D cleanrooms operating under ISO/IEC 17025 or GLP-compliant workflows.

Key Features

• Zero-condensate operation: SPEM-based dehumidification releases moisture exclusively as gaseous H₂ and O₂—no liquid accumulation, no drip trays, and no risk of secondary contamination.
• Ultra-low power consumption: Rated at only 4 W average draw, enabling continuous 24/7 operation without thermal load impact on adjacent instrumentation or HVAC systems.
• Acoustically silent architecture: Absence of compressors, fans, or rotary actuators ensures vibration-free storage—critical for interferometry-grade optics, quartz crystal microbalances, and gravimetric analysis setups.
• Optimized spatial utilization: Smooth internal corners, full-height transparent PMMA walls, and recessed door seals eliminate dead zones; internal volume (236 L) is fully accessible without shelf obstruction.
• Modular mobility: Four φ65 mm polyamide casters—including two dual-action braking units—support controlled relocation while maintaining stability during weighing or sample handling.
• Robust material system: PMMA body offers >92% visible light transmission and UV resistance (300–400 nm); anodized aluminum frame provides structural rigidity and ESD-safe grounding compatibility.

Sample Compatibility & Compliance

The SP-BGKFN-P maintains stable relative humidity below 5% RH at 23 °C ambient, verified per ASTM E104-22 (Standard Practice for Maintaining Constant Relative Humidity). It complies with IEC 61000-6-3 (EMC emission limits) and IEC 61010-1 (safety requirements for electrical equipment for measurement, control, and laboratory use). The absence of oil-lubricated pumps or desiccant beds eliminates organic outgassing—ensuring compatibility with USP pharmaceutical packaging testing protocols and ISO 14644-1 Class 5 cleanroom auxiliary storage. Optional NIST-traceable hygrometer integration supports audit-ready humidity logging per FDA 21 CFR Part 11 requirements when paired with validated data acquisition software.

Software & Data Management

While the base SP-BGKFN-P operates as a standalone analog-controlled unit, its optional RS-485 interface (add-on module AS-DCOM-01) enables integration into LabVantage, Thermo Fisher SampleManager, or custom SCADA systems. Real-time RH and cabinet temperature telemetry can be logged at user-defined intervals (1–300 s), with configurable alarm thresholds (e.g., RH >7.5% for 60 s triggers relay output and email alert via SMTP gateway). All data records include timestamp, operator ID (via RFID badge scan), and device serial number—meeting ALCOA+ principles for data integrity in GMP-regulated environments.

Applications

• Long-term storage of certified reference materials (CRMs) requiring ≤5% RH per ISO Guide 35.
• Pre-conditioning of filter membranes and chromatography columns prior to gravimetric or solvent-residue analysis.
• Stabilization of piezoelectric sensors and MEMS devices prior to calibration under controlled humidity.
• Moisture management for X-ray diffraction (XRD) sample holders and electron microscopy grid storage.
• Backup humidity control for gloveboxes handling air-sensitive catalysts or organometallic compounds.

FAQ

Does the SP-BGKFN-P require periodic desiccant replacement?

No. The solid polymer electrolyte membrane operates continuously without consumables and has a rated service life of ≥10,000 hours under nominal conditions.
Can the cabinet be connected to an external vacuum source?

Yes—optional vacuum port (M6 thread, ISO-KF16 compatible) allows connection to scroll or diaphragm vacuum pumps for accelerated drying cycles down to 10⁻² mbar.
Is the PMMA body resistant to common solvents used in lab cleaning?

PMMA exhibits excellent resistance to alcohols, acetone, and dilute acids/bases, but is incompatible with chlorinated hydrocarbons (e.g., chloroform) and strong alkalis (>10% NaOH); refer to AS ONE Chemical Resistance Chart v3.2 for full compatibility matrix.
What safety certifications does the unit carry?

It bears PSE mark (Japan), CE marking (EMC & LVD directives), and conforms to UL 61010-1 Third Edition for laboratory electrical safety.
How is traceability maintained during calibration verification?

Each unit ships with a factory-issued calibration certificate (traceable to NMIJ/AIST), including RH deviation data at three points (10%, 30%, and 50% RH) measured using a chilled-mirror hygrometer (Michell OptiDew VPro).
