Overview
The Erlab Shelf 812B Filtered Air Medicine Storage Cabinet is an under-bench, recirculating chemical storage solution engineered for proximity-based, low-risk handling of frequently used reagents and pharmaceutical substances in analytical, QC, and research laboratories. Unlike conventional ventilated cabinets requiring ducted exhaust, the Shelf 812B employs Erlab’s proprietary NanoPure™ unidirectional airflow and dual-stage molecular filtration technology to continuously purify internal cabinet air and ambient air drawn from the lab environment. It operates on the principle of active air recirculation: ambient air enters the cabinet through a front intake grille, passes sequentially through a pre-filter (capturing particulates >5 µm) and a high-capacity composite adsorbent bed (targeting acidic gases such as HCl, HF, NOx, and organic vapors including acetone, methanol, and chlorinated solvents), and is returned to the lab space at a safe, filtered concentration—eliminating ductwork, reducing HVAC load, and maintaining room air balance. Designed specifically for integration beneath standard laboratory work surfaces, it delivers immediate access to critical reagents without compromising occupational exposure limits (OELs) or indoor air quality.
Key Features
- Compact under-bench footprint (650 × 551 × 760 mm) optimized for space-constrained labs and modular bench configurations
- Dual-stage filtration system certified to ASTM D5209–22 and ISO 10121–2 standards for removal efficiency ≥99.5% against representative challenge agents (e.g., SO2, NH3, acetone, formaldehyde)
- Real-time filter saturation indicator with visual LED status display and audible alert—enabling proactive maintenance per manufacturer-recommended service intervals
- Non-ducted operation compliant with ASHRAE 110–2016 and EN 14175–3:2022 for local containment performance
- Corrosion-resistant epoxy-coated steel interior and spill-containment sump (1.5 L capacity) meeting USP secondary containment requirements for hazardous drug handling
- Integrated airflow sensor and microprocessor-controlled fan delivering consistent face velocity (0.5 m/s ± 10%) across full operational load
Sample Compatibility & Compliance
The Shelf 812B is validated for safe storage of Class I–III flammable liquids (per NFPA 30), corrosive acids and bases (e.g., HNO3, NaOH), and low-volatility pharmaceutical intermediates. It is not rated for Class IV flammables, peroxides, or pyrophoric substances. Cabinet construction complies with EN 14727:2015 for laboratory furniture safety and stability, and its filtration performance supports adherence to OSHA 29 CFR 1910.1200 (HazCom), EU CLP Regulation (EC No. 1272/2008), and ISO 45001:2018 occupational health management systems. When deployed in GxP environments, its filter replacement logs and airflow verification records support GLP audit trails per OECD Principles of Good Laboratory Practice.
Software & Data Management
While the Shelf 812B operates as a standalone unit without embedded software, its integrated sensor suite outputs analog voltage signals (0–10 V DC) corresponding to airflow rate and filter differential pressure—compatible with third-party building management systems (BMS) or lab-wide IoT monitoring platforms via optional analog-to-digital gateway modules. Erlab provides a downloadable Excel-based Filter Life Tracker tool (v3.1), enabling users to log installation dates, cumulative runtime hours, and environmental VOC concentration estimates to generate predictive replacement schedules aligned with ISO 14644–1 cleanroom data integrity expectations.
Applications
- Storing daily-use solvents (e.g., ethanol, isopropanol, acetonitrile) adjacent to HPLC, GC, or dissolution testing stations
- Holding pH standards, buffer concentrates, and titrants within reach of analytical balances and titrators while minimizing ambient CO2 or humidity interference
- Securing cytotoxic or potent compound stock solutions in pharmacy compounding labs under USP and spatial control guidelines
- Supporting lean lab workflows by reducing walk-time between storage and instrumentation—validated in time-motion studies across ISO/IEC 17025-accredited testing facilities
FAQ
Does the Shelf 812B require external ducting or electrical modifications?
No—it operates on standard 100–240 V AC, 50/60 Hz power and requires no wall penetrations or exhaust infrastructure.
Can it be used for storing hydrofluoric acid (HF)?
Yes—its acid gas filter media includes impregnated alumina and potassium hydroxide layers validated for HF adsorption per ASTM D5209 Annex A4.
How often must the filters be replaced?
Under typical lab use (8 hrs/day, moderate VOC load), replacement is recommended every 6–12 months; actual interval depends on usage intensity and is determined by the built-in saturation monitor.
Is the cabinet compliant with fire safety codes for chemical storage?
It meets structural fire resistance requirements of EN 14727 but is not classified as a fire-rated storage cabinet (e.g., FM Global 6050); flammable liquid quantities stored must comply with local fire authority limits.
Can multiple Shelf 812B units be networked for centralized monitoring?
Not natively—but analog outputs enable integration into existing BMS or SCADA systems using industry-standard Modbus RTU or BACnet MS/TP protocols via external interface hardware.
