Erlab 822 Air-Filtered Chemical Storage Cabinet

Overview

The Erlab 822 Air-Filtered Chemical Storage Cabinet is an engineered solution for the safe, ventilated containment of volatile, odorous, or low-to-moderate hazard chemicals in non-fume-hood laboratory environments. Unlike traditional sealed storage cabinets, the 822 operates on a dynamic air-filtering principle: ambient air is continuously drawn through the cabinet interior, passed through a dual-stage filtration system—typically comprising a pre-filter for particulates and an activated carbon filter bed for organic vapors—and then safely recirculated into the laboratory space. This closed-loop, filter-mediated airflow eliminates the need for external ducting while maintaining a slight negative pressure inside the cabinet to prevent uncontrolled vapor escape. Designed for ISO 14644-compliant cleanroom-adjacent labs and GLP-regulated quality control facilities, the 822 supports passive chemical stewardship without compromising room air balance or HVAC load.

Key Features

• Self-contained filtration architecture with real-time filter saturation monitoring via integrated pressure differential sensors
• Ergonomic front-access design with full-height transparent polycarbonate door (anti-static, UV-stabilized) and magnetic safety latch
• Adjustable, corrosion-resistant polypropylene shelves with 30 mm vertical pitch and 30 kg uniform load capacity per shelf
• Integrated LED task lighting (3000 K CCT, IP44 rated) with motion-activated activation and manual override
• CE-marked electrical system compliant with IEC 61000-6-3 (EMC) and IEC 61000-6-2 (immunity), certified to EN 61010-1 for laboratory equipment safety
• Modular filter cartridge system enabling tool-free replacement; standard configuration includes 3.2 kg activated carbon mass with ≥90% adsorption efficiency for common solvents (acetone, ethanol, ethyl acetate, toluene) at 25°C and 50% RH

Sample Compatibility & Compliance

The Erlab 822 is validated for storage of Class I–III hazardous substances as defined in GHS Annex I, including flammable liquids (Category 2–3), health hazards (Category 3–4), and acute toxicity (Category 4). It is not intended for perchloric acid, hydrofluoric acid, cyanide salts, or pyrophoric materials. Cabinet construction meets EN 14727:2006 for laboratory furniture mechanical stability and EN 16121:2012 for chemical resistance of polymer surfaces. Filter performance data are generated per ASTM D5228-18 (carbon tetrachloride activity) and ISO 10121-1:2013 (gas-phase filtration testing). Documentation packages include EU Declaration of Conformity, filter performance certificates, and material safety data sheets for all interior components.

Software & Data Management

While the 822 operates as a standalone unit without embedded microprocessors, it integrates with Erlab’s optional SmartLink Gateway (sold separately) for remote filter life tracking, airflow verification logs, and event-based notifications via SNMP or email. All operational parameters—including cumulative runtime, filter usage hours, and last service timestamp—are stored locally in non-volatile memory and exportable as CSV files via USB-C port. Audit trails comply with ALCOA+ principles and support 21 CFR Part 11-compliant environments when paired with validated LIMS or ELN platforms. Firmware updates are delivered via signed firmware packages verified using SHA-256 cryptographic checksums.

Applications

• Storing working-stock reagents in analytical chemistry labs where fume hood access is limited or reserved for active procedures
• Securing solvent libraries in HPLC and GC laboratories to minimize ambient contamination and cross-contamination risks
• Holding pH standards, buffer tablets, and calibration solutions in metrology labs requiring stable, low-vapor environments
• Supporting ISO/IEC 17025-accredited testing facilities needing documented, traceable chemical storage conditions
• Supplementing central chemical stores in university teaching labs where ventilation infrastructure cannot accommodate ducted cabinets

FAQ

Does the Erlab 822 require external exhaust ducting?

No. It is a ductless, recirculating system relying solely on internal filtration.
How often must the carbon filter be replaced?

Filter service interval depends on chemical load and volatility; typical range is 6–12 months under moderate use. The built-in pressure sensor alerts users at ≥80% saturation.
Can the cabinet be used for storing acids or bases?

Yes—for low-concentration aqueous solutions (e.g., ≤1 M HCl, ≤1 M NaOH); however, concentrated mineral acids, oxidizers, and alkalis exceeding pH 12 or pH 2 require dedicated acid/corrosive cabinets.
Is the 822 suitable for radioactive or biological agents?

No. It is not certified for radiological containment or biosafety-level applications.
What certifications does the unit carry for North American markets?

It carries CE marking for EU compliance; UL/ETL listing is available upon request for specific configurations under UL 969 and UL 61010-1.
