Biobase BSC-1100IIB2 Biological Safety Cabinet
The BSC-1100IIB2 is a Class II Type B2 biosafety cabinet delivering uncompromising 100% total exhaust containment for handling volatile toxic chemicals, radionuclides, and Biosafety Level 3 (BSL-3) agents. Unlike Type A2 models, it exhausts all internal air directly to the facility’s dedicated ductwork, eliminating recirculation and preventing buildup of hazardous vapors. This makes it the preferred choice for oncology pharmacies, toxicology labs, and research involving carcinogens, anesthetics, or radioisotopes, ensuring zero risk of aerosol or chemical re-entry into the workspace.
Description
Airflow and Filtration Performance: Engineered for absolute containment, it maintains a precise inflow velocity of 0.55 ± 0.025 m/s and downflow velocity of 0.35 ± 0.025 m/s, creating a robust laminar curtain that isolates the work zone. Dual HEPA filters (99.999% efficiency at 0.3 μm) on both supply and exhaust streams capture all particulates, while an external exhaust blower (required) pulls 100% of contaminated air through a dedicated hard-ducted system. Real-time digital sensors monitor airflow, pressure differentials, and filter loading, with automatic compensation and visual/audible alarms for deviations, ensuring compliance with NSF/ANSI 49 and EN 12469 standards.
Work Surface and Accessibility: Provides a generous internal workspace of 940 × 600 × 660 mm (W × D × H)* ideal for procedures requiring chemical fume management, such as solvent-based staining or tracer labeling. The motorized front sash opens to a maximum of 420 mm (17 inches), with a certified safe working height of 200 mm (8 inches). The 10° sloped front panel reduces glare and fatigue, while the one-piece 304 stainless-steel work tray with raised edges contains spills and supports steam sterilization. Integrated drainage ports and seamless corners simplify decontamination.
User Interface and Operational Features: Features a 7-inch color touchscreen with intuitive graphical interface, displaying real-time airflow, sash position, filter life, and exhaust status in up to 8 languages. Interlock logic prevents UV activation when the sash is open or blower is off. The SmartSafe™ system includes a programmable UV timer (0–99 min), auto-shutdown delay, and memory backup for settings. Dual LED lighting (≥1200 lux) ensures shadow-free visibility, and ≤62 dB operation maintains a quiet lab environment. Optional foot pedal control enhances hands-free workflow.
Sterilization and Maintenance: Equipped with a 30W UV-C lamp (253.7 nm) for rapid surface sterilization, with elapsed-hour tracking and automatic shutoff. The cabinet’s tool-free HEPA filter replacement and removable work surface reduce downtime. A dedicated exhaust transition (8-inch or 10-inch collar) ensures secure duct connection, and the separated base design allows easy access for annual certification. All surfaces are 304 stainless steel with coved corners for wipe-down efficiency.
Electrical and Environmental Specifications: Operates on AC 220V/50Hz at 600W (excluding external exhaust blower), with built-in surge protection and low-energy EC motor. Designed for ambient conditions of 15–35°C and ≤80% RH, it includes negative pressure monitoring between the work zone and downflow plenum, with alarms for pressure loss. The unit requires a facility exhaust system capable of 400–600 CFM (adjustable via damper) to maintain negative pressure.
Dimensions and Installation Flexibility:
Compact external dimensions of 1100 × 800 × 2250 mm (W × D × H) fit through standard doorways, with a net weight of 180 kg for stability. Includes an adjustable hydraulic stand (700–900 mm height) and optional casters. The **top-mounted exhaust collar** supports rigid or flexible ducting, and front service panels enable in-place filter testing (PAO challenge ports included). Requires minimum 30 cm clearance on sides and rear for airflow and maintenance.
- Throughput and Workflow: Continuous 24/7 operation with no recirculation, supporting high-volume cytotoxic drug preparation or radio-pharmacy workflows.
- Detection and Monitoring: Triple-sensor system (inflow, downflow, exhaust) with digital pressure transducers; logs 10,000+ events including alarms and sash movements.
- Detection Principle: 100% HEPA-filtered total exhaust with laminar downflow and negative pressure containment; no internal recirculation.
- Additional Features: Built-in dual 220V GFCI-protected outlets inside chamber; RS485/USB ports for data export; supports external thermal printer with multi-template reporting (filter life, usage logs).
- Data Storage: 100,000+ records including airflow trends, UV usage, error codes, and timestamps; exportable in CSV/PDF.
- Sample Handling Modes: Optimized for volatile chemicals, powders, and biohazards; compatible with sealed transfer ports, bag-in/bag-out systems, and glove ports.
