Bigneat Chemcap Store Ventilated Chemical Storage Cabinet

Overview

The Bigneat Chemcap Store Ventilated Chemical Storage Cabinet is an engineered solution for safe, localized containment and continuous air purification in laboratory environments where volatile chemicals are routinely stored or handled. Unlike traditional ducted fume hoods or fixed chemical storage rooms, this cabinet operates on a closed-loop, recirculating filtration principle—drawing ambient air from the laboratory interior, passing it sequentially through high-efficiency particulate air (HEPA) and chemically selective adsorption media, then returning filtered air back into the room. This design eliminates the need for external ductwork, structural modifications, or HVAC integration, making it ideal for retrofit installations, modular labs, or temporary facilities operating under space or budget constraints. The system adheres to core occupational health and safety principles outlined in ISO 15190:2020 (Laboratory safety — General requirements) and supports compliance with local workplace exposure limits (e.g., OSHA PELs, ACGIH TLVs®) by actively reducing airborne concentrations of vapors, aerosols, and fine particulates generated during routine bottle opening, dispensing, or minor spill events.

Key Features

• Recirculating filtration architecture with dual-stage capture: pre-filter + HEPA (optional) + chemically impregnated activated carbon media
• Quiet operation at ≤50 dBA (measured at 1 m), enabling deployment in shared or sensitive workspaces without acoustic disruption
• Modular footprint options: compact shelf-style units (CS812, CS822) and full-height cabinet configurations (CS834, CS844) with lockable magnetic door latches
• Spill containment integrated into all models—standard polyethylene spill trays and absorbent pads rated for common solvents, acids, and bases
• Adjustable-height internal shelving (CS834/CS844) for optimized bottle stacking and ergonomic access
• Optional electronic filter saturation monitor (ESM) with visual/audible alerts for organic solvent applications
• Configurable compartmentalization: upgrade paths available to 10 (XC) or 20 (XXC) independent storage zones for segregation of incompatible chemical classes

Sample Compatibility & Compliance

The Chemcap Store accommodates standard laboratory containers—including 1 L HDPE or glass bottles, solvent cans, reagent jars, and small-volume ampoules—within its standardized internal dimensions. All cabinet models comply with EN 14175-3:2019 (Fume cupboards — Part 3: Type test methods) for airflow uniformity and containment performance when operated per manufacturer instructions. Optional HEPA filtration meets ISO 14644-1 Class 5 (ISO Class 5) particle removal efficiency ≥99.995% at 0.3 µm. Filter selection aligns with chemical class-specific adsorption isotherms: OS (organic solvents), H+ (volatile acids), F (formaldehyde), AM (ammonia), and MP (multi-purpose broad-spectrum). Each filter type undergoes batch validation per ASTM D5228–19 (Standard Test Method for Determining Adsorption Capacity of Activated Carbon) and carries traceable lot documentation for GLP/GMP traceability.

Software & Data Management

While the base Chemcap Store operates as a standalone mechanical-electrical system without embedded firmware, optional ESM modules log cumulative runtime and generate timestamped saturation events via LED indicators and audible tones. No proprietary software is required; however, ESM output signals (dry contact or 0–10 V analog) can be interfaced with existing building management systems (BMS) or laboratory information management systems (LIMS) for centralized maintenance tracking. Filter replacement records—including lot number, installation date, and end-of-service verification—are maintained manually in accordance with ISO/IEC 17025:2017 clause 7.7 (Control of equipment) and support audit readiness for UKAS, CAP, or FDA 21 CFR Part 11–aligned environments where documented change control is mandated.

Applications

• Secondary storage of low-to-moderate volatility reagents in teaching laboratories, QC/QA labs, and pilot-scale R&D facilities
• On-bench containment for frequently accessed solvents (e.g., acetone, ethanol, hexane) where full ducted hood use is impractical
• Segregated storage of acid-sensitive compounds adjacent to alkaline reagents using multi-compartment CS844 configurations
• Temporary containment during lab renovation or relocation projects where permanent ventilation infrastructure is unavailable
• Compliance support for CLP/GHS labeling requirements by minimizing ambient vapor accumulation near hazard signage zones

FAQ

Does the Chemcap Store require external ducting or HVAC modification?
No. It operates as a self-contained recirculating unit and requires only a standard 100–240 V AC power supply.
Can I mix different chemical classes within a single cabinet?
We strongly recommend segregation by compatibility group. Multi-compartment upgrades (XC/XXC) and model-specific filter selection enable safe co-storage only when verified via NFPA 45 or GESTIS Substance Database cross-reactivity analysis.
How often must filters be replaced?
Service life depends on chemical load, concentration, and usage frequency. Under typical academic lab conditions (≤2 hrs/day average operation), OS-type filters last 6–12 months; H+-type filters may require replacement every 3–6 months in high-acid environments. ESM monitoring provides objective endpoint detection.
Is the cabinet suitable for flammable liquid storage?
Yes—CS834 and CS844 models meet EN 14470-1:2013 fire resistance requirements for flammable liquid cabinets (30-minute integrity rating) when equipped with certified fire-rated gaskets and self-closing doors.
What documentation accompanies each unit?
Each shipment includes CE Declaration of Conformity, UKCA marking certificate (for UK deliveries), filter performance datasheets, EN 14175-3 test reports, and a GLP-compliant installation and maintenance logbook template.
