Overview
The Erlab Ministore 822 B is a compact, self-contained air-filtered chemical storage cabinet engineered for safe, localized containment and purification of volatile organic compounds (VOCs), acids, bases, and other hazardous vapors emitted from laboratory reagents. Unlike traditional ventilated cabinets that exhaust to the outside environment, the Ministore 822 B operates on a closed-loop recirculation principle: ambient air is drawn into the cabinet via an integrated low-noise centrifugal blower, passed through a dual-stage molecular filtration system—comprising high-capacity activated carbon and chemically impregnated media—and returned as purified air directly into the laboratory space. This design eliminates ductwork requirements, reduces HVAC load, and supports energy-efficient, flexible placement in fume hood-perimeter zones, satellite prep areas, or quality control laboratories where permanent ventilation infrastructure is unavailable or impractical.
Key Features
- Compact footprint (820 × 350 × 730 mm) optimized for benchtop, wall-mount, or pedestal installation—no external ducting or civil works required.
- Dual-stage molecular filtration with real-time saturation monitoring: pre-filter captures particulates; main filter targets VOCs, aldehydes, ammonia, hydrogen sulfide, and halogenated solvents per EN 14175-3 test protocols.
- Intelligent airflow management ensures uniform vapor capture across the entire interior volume, minimizing dead zones and maintaining consistent face velocity (>0.3 m/s at access opening).
- Integrated LED status indicators provide visual feedback for power, airflow integrity, and filter service life—enabling proactive maintenance scheduling aligned with ISO/IEC 17025 internal audit requirements.
- Robust steel construction with epoxy-powder-coated finish resists corrosion from incidental chemical splashes; adjustable leveling feet and optional wall-anchoring kit ensure stability under ISO 14001-compliant lab layouts.
Sample Compatibility & Compliance
The Ministore 822 B is validated for continuous storage of common laboratory chemicals including acetone, ethanol, methanol, chloroform, hydrochloric acid (dilute), sodium hydroxide solutions, and formaldehyde-containing reagents. It complies with European standard EN 14175-3 (laboratory fume cupboards – Part 3: Requirements for air-filtered units) and meets CE marking requirements for electromagnetic compatibility (EMC Directive 2014/30/EU) and low-voltage safety (LVD Directive 2014/35/EU). While not a substitute for full-scale fume hoods in high-risk synthesis applications, it satisfies OSHA 1910.1200 (Hazard Communication Standard) and EU CLP Regulation (EC No. 1272/2008) requirements for secondary containment and exposure minimization during routine reagent handling. Filter replacement intervals are determined by cumulative runtime and chemical loading profile—not fixed calendar dates—supporting GLP-aligned documentation practices.
Software & Data Management
The Ministore 822 B operates as a standalone unit without embedded software or network connectivity. However, its mechanical and filtration performance parameters are fully traceable via factory calibration records and third-party validation reports (available upon request). Filter service logs—including installation date, estimated saturation timeline, and replacement confirmation—can be maintained manually in laboratory notebooks or integrated into existing CMMS platforms (e.g., LabWare LIMS, Veeva Vault) using standardized SOP templates. For labs operating under FDA 21 CFR Part 11, Erlab provides optional electronic filter lifecycle tracking add-ons compatible with qualified audit-trail systems.
Applications
- Secondary storage of frequently accessed solvents and standards in analytical labs (HPLC, GC, ICP-MS preparation zones).
- Secure holding of cytotoxic or genotoxic compounds in pharmaceutical QC environments where ISO 13485 and ICH Q5C compliance is mandated.
- Decentralized chemical inventory management in teaching labs, university core facilities, or field-deployable mobile labs.
- Supplemental vapor control adjacent to open-beaker operations, weighing stations, or sample dilution benches lacking dedicated hood coverage.
- Temporary containment during method development phases where long-term fume hood allocation is constrained.
FAQ
Does the Ministore 822 B require external exhaust ducting?
No. It is a ductless, recirculating system designed for plug-and-play operation using standard AC power.
How often must the molecular filter be replaced?
Filter service life depends on chemical type, concentration, and usage frequency; typical range is 6–12 months under moderate use. Erlab provides a filter saturation calculator based on compound-specific breakthrough data.
Can it be mounted on a wall?
Yes—the cabinet includes pre-drilled mounting points and optional wall-fixing hardware for secure vertical installation per EN 16005 stability guidelines.
Is it suitable for storing flammable liquids?
It is not certified as a Class I, Division 1 flammable storage cabinet (per NFPA 30 or UL 1275); users must verify compatibility with local fire codes and perform risk assessment per ISO/IEC 31010.
What documentation is provided for regulatory audits?
CE Declaration of Conformity, EN 14175-3 test report summary, filter material SDS, and factory calibration certificate are supplied with each unit.
