Titan SCB-4 4-Gallon (15 L) Corrosion-Resistant Chemical Safety Cabinet

Overview

The Titan SCB-4 is a 4-gallon (15 L) dedicated safety cabinet engineered for the secure storage of weakly corrosive liquids—such as dilute acids (e.g., acetic, phosphoric, or citric acid solutions), low-concentration alkaline solutions, and mildly aggressive solvents—in laboratory, pharmaceutical QC, and industrial R&D environments. Unlike standard flammable liquid cabinets, the SCB-4 integrates material-level corrosion resistance without compromising structural integrity or regulatory compliance. Its design adheres to fundamental principles of chemical containment: vapor suppression through tight-sealing dual doors, passive ventilation via calibrated bottom and top vents, and leak containment within a fully welded, seamless sump tray rated for ≥15 L capacity. The cabinet operates as a passive engineering control—not a fume hood—and is intended for use in well-ventilated rooms meeting local occupational health and safety requirements (e.g., OSHA 1910.1200, ANSI Z9.11).

Key Features

• Corrosion-resistant construction: All interior surfaces—including sump, shelves, door liners, and hinge assemblies—are fabricated from 1.2 mm thick, electropolished 304 stainless steel with passivated finish to resist pitting and crevice corrosion from repeated exposure to pH 2–6 aqueous solutions.
• Double-walled, self-closing doors with 3-point positive-latching mechanism ensure reliable closure under vibration and meet NFPA 30 minimum door retention criteria.
• Integrated 2-inch (50 mm) adjustable leveling feet with non-marking polyurethane caps accommodate uneven flooring while maintaining sump integrity and spill containment geometry.
• Removable, perforated stainless-steel shelves (2 included) support uniform airflow and allow rapid visual inspection of container integrity; load rating: 35 kg per shelf (evenly distributed).
• No internal electrical components—compliant with Class I, Division 2 hazardous location requirements where applicable—eliminating ignition risk during storage of volatile, weakly corrosive mixtures.

Sample Compatibility & Compliance

The SCB-4 is validated for storage of liquids with low to moderate chemical aggressiveness, including but not limited to: diluted hydrochloric acid (≤10% v/v), sulfuric acid (≤5% v/v), sodium hydroxide solutions (≤1 M), ethanol/water blends containing organic acids, and buffer solutions used in bioprocessing. It is not rated for strong oxidizers (e.g., concentrated nitric acid), halogenated solvents, or hydrofluoric acid. The cabinet conforms to structural and dimensional benchmarks aligned with EN 14470-1:2019 (Fire Resistance) for Category A cabinets, and incorporates design elements consistent with UL 1275 (Standard for Safety – Flammable Liquid Storage Cabinets) regarding door operation, sump capacity, and ventilation port placement. While not certified for explosion-proof operation, its passive containment architecture supports GLP-compliant documentation of chemical inventory and storage conditions.

Software & Data Management

The SCB-4 is a standalone mechanical cabinet with no embedded electronics, firmware, or connectivity features. This design philosophy prioritizes reliability, longevity, and audit readiness in regulated settings where electronic logging may introduce validation complexity. Users are expected to maintain manual logs—per ISO/IEC 17025 Clause 8.5.2 and FDA 21 CFR Part 11 Annex A guidance—for contents, inspection dates, and maintenance records. Optional accessories include barcoded asset tags and laminated chemical compatibility reference charts (available upon request), facilitating integration into existing LIMS or EHS management systems.

Applications

• Storing pH calibration standards and titrant solutions in analytical chemistry labs
• Holding cleaning agents and passivation baths in cleanroom maintenance workflows
• Securing buffer stock solutions and mild reagents in cell culture and molecular biology core facilities
• Temporary staging of low-hazard etchants in microfabrication or materials characterization labs
• Supporting GMP-aligned raw material staging zones where segregation of weakly reactive substances is required per ICH Q7 Section 5.22

FAQ

Does the SCB-4 meet OSHA or EPA requirements for corrosive storage?
Yes—the cabinet satisfies OSHA’s general duty clause (Section 5(a)(1)) for hazard mitigation and aligns with EPA secondary containment expectations under 40 CFR 264.175 when used with documented spill response procedures.
Can it be used for flammable liquids?
No. The SCB-4 is not UL-listed or FM-approved for flammables. For Class I liquids, Titan recommends the SCB-F series, which features flame arrestors and explosion-relief panels.
Is third-party fire-resistance certification available?
The SCB-4 has undergone internal 10-minute fire exposure testing per EN 14470-1 Annex B methodology; full third-party certification is available as an optional add-on service with lead-time extension.
What maintenance is required?
Quarterly visual inspection of door seals, latch function, and sump integrity is recommended. Stainless steel surfaces may be cleaned with pH-neutral detergent and deionized water; avoid chloride-based cleaners.
