SuJin AnTai BSC-1300IIA2 Class II Type A2 Biological Safety Cabinet

Overview

The SuJin AnTai BSC-1300IIA2 is a Class II, Type A2 biological safety cabinet engineered for precision containment in biosafety level 2 (BSL-2) and select BSL-3 applications involving low-to-moderate risk biological agents. It operates on the principle of inward airflow (personnel protection), downward laminar airflow (product protection), and recirculated/externally exhausted air (environmental protection), conforming strictly to NSF/ANSI 49-2002 performance requirements. The cabinet integrates a dual-airflow architecture with independent supply and exhaust systems, maintaining stable inflow velocity (≥0.55 m/s) and downward velocity (0.33 ± 0.015 m/s) via real-time pressure-sensing feedback and adaptive motor control. Its structural integrity ensures continuous negative-pressure containment within the work chamber—verified at 500 Pa ±10%—and eliminates leakage across all sealed interfaces, including the patented zero-leakage filter mounting system (Patent No. ZL200520140347.2). Designed for uninterrupted 24-hour operation under ambient conditions of 0–40°C and ≤85% RH, the BSC-1300IIA2 delivers ISO Class 4 (Fed. Std. 209E Class 10) cleanroom-grade air quality in the work area.

Key Features

• ULPA filtration system using U.S.-sourced HV ultra-low penetration air filters with ≥99.999% efficiency at 0.12 μm particle size; supplemented by HEPA pre-filters (≥99.995% @ 0.3 μm)
• Japanese AIR TECH intelligent variable-frequency blower system with automatic airflow compensation—maintains ±10% velocity stability even with >50% filter loading
• Electro-mechanical front sash with imported Japanese suspension lift mechanism: 6-mm tempered anti-explosion glass, frictionless positioning, full closure capability for decontamination cycles
• Monolithic 304 stainless steel work surface and R10 radius-welded inner chamber for seamless cleaning and corrosion resistance; integrated 4000 mL liquid collection trough with drain valve
• Microprocessor-based control panel with LCD interface: real-time monitoring of inflow/downflow velocities, filter service life, fan status, sash height, total runtime, and audible/visual alarms for out-of-spec conditions
• Dual independent power circuits with surge-protected outlets; interlocked UV lamp (30 W) activated only when sash is fully closed and fans are off; programmable 30-min auto-shutoff
• Integrated Dwyer differential pressure gauge for direct visual verification of static pressure differentials across filters and plenums
• Modular base frame design enabling precise leveling on uneven floors and facilitating transport without disassembly

Sample Compatibility & Compliance

The BSC-1300IIA2 supports a broad range of microbiological, virological, and cell culture workflows—including HIV serological screening, clinical diagnostic sample processing, and pharmaceutical aseptic manipulations. It has been validated per NSF/ANSI 49-2002 protocols for personnel, product, and environmental protection using Bacillus subtilis spore challenge tests (5–8 × 10⁸ CFU/mL aerosolized suspension). Performance metrics include: personnel protection ≤10 CFU/sample (impactor), ≤5 CFU/sample (slit sampler); product protection ≤5 CFU/sample; cross-contamination protection ≤2 CFU/sample. Structural leak-tightness complies with ISO 10648-1 for Class 1 containment enclosures. All materials—including silicon-borosilicate glass fiber filter media—are certified non-outgassing and chemically inert under standard lab humidity and temperature ranges. The unit meets CE marking requirements for medical devices (MDR 2017/745) and is compatible with GLP-compliant laboratory documentation practices.

Software & Data Management

The embedded microcontroller logs operational parameters—including cumulative runtime, filter delta-P trends, sash position history, and alarm events—with timestamped records stored locally for ≥12 months. While no external software suite is bundled, data export is supported via RS-232 serial interface for integration into centralized LIMS or electronic lab notebook (ELN) platforms. Audit trail functionality satisfies FDA 21 CFR Part 11 requirements for secure user authentication, change tracking, and record retention. System firmware updates are performed via USB port with cryptographic signature verification to prevent unauthorized modification. Calibration and validation reports generated during commissioning are structured to align with ISO/IEC 17025 accreditation criteria for testing laboratories.

Applications

• Clinical diagnostics: HIV rapid test confirmation, TB culture isolation, bloodborne pathogen handling
• Pharmaceutical QC: sterility testing of injectables, microbial limit assays, media fill simulations
• Academic research: mammalian cell line maintenance, lentiviral transduction, CRISPR-Cas9 editing workflows
• Public health infrastructure: national disease surveillance labs, provincial CDC biosafety core facilities
• Veterinary diagnostics: zoonotic agent isolation (e.g., avian influenza, Brucella spp.) under BSL-2 containment

FAQ

Does the BSC-1300IIA2 comply with international biosafety standards?
Yes—it is fully certified to NSF/ANSI 49-2002 and validated against ISO 10648-1 for containment integrity.
What is the expected service life of the ULPA filter under typical usage?
Under continuous operation with standard particulate load, filter lifespan averages 3–5 years; real-time delta-P monitoring triggers replacement alerts before performance degradation occurs.
Can the cabinet be connected to a building’s dedicated exhaust ductwork?
Yes—equipped with a 200 mm diameter hard-ducted exhaust collar compatible with standard HVAC backpressure specifications (≤125 Pa).
