The Biological Clean Bench is a Class II laminar flow workstation providing ISO 5 (Class 100) sterile environments for microbiological experiments and cell culture. Available in vertical (900/1200mm width) and horizontal airflow models, it features HEPA H14 filters (99.995% efficiency @0.3μm) and UV-C sterilization. The ergonomic design includes a sloped front window, adjustable work surface, and low-noise fan (<55dB)—ideal for biopharmaceutical labs, clinical diagnostic facilities, and academic research centers. It complies with EN 12469 and NSF/ANSI 49 standards.
Biomedical labs use vertical-flow clean benches for stem cell culture. The downward laminar flow (0.45m/s) prevents cross-contamination between cell lines, while the UV lamp (pre-experiment 30-minute sterilization) eliminates microbial contaminants on the work surface.
Food safety labs utilize horizontal-flow models for colony counting. The open front design allows easy access to Petri dishes, and the integrated airfoil reduces turbulence—ensuring accurate CFU (colony-forming unit) results compliant with ISO 6887.
Quality control labs prepare drug samples in the clean bench to avoid particulate contamination. The stainless steel work surface (resistant to organic solvents) and removable side panels facilitate cleaning between samples, supporting GMP documentation.
Class 100 Sterile Environment: HEPA H14 filters + pre-filters (G4) deliver 0.3-0.5m/s laminar flow, meeting ISO 5 standards.
Dual Sterilization: 254nm UV-C lamp (10W) with timer + optional UV intensity monitor, and HEPA-filtered airflow for continuous decontamination.
Ergonomic Design: 10° sloped front window (anti-reflective glass), height-adjustable work surface (750-850mm), and low-noise fan (<55dB).
Safety & Compliance: Window interlock (UV stops when open), LED working status indicator, and material certification for GMP audits.
Model Selection: Recommend vertical/horizontal models based on experiment type (e.g., vertical for hazardous samples, horizontal for routine work).
Installation & Testing: On-site airflow velocity mapping, filter integrity testing (DOP test), and calibration of UV intensity.
Training: Operator training on filter replacement, UV safety, and daily maintenance (e.g., surface disinfection with 75% ethanol).
After-Sales: 1-year warranty, filter replacement reminders, and 24-hour technical support for airflow anomalies.
A1: Vertical flow (downward) is better for hazardous samples (e.g., pathogenic microbes) as it contains aerosols. Horizontal flow (forward) suits routine work (e.g., pipetting) and offers easier access.
A2: Under normal use (8 hours/day), HEPA filters last 12-18 months. The pressure gauge alerts when resistance exceeds 250Pa (replacement required).
A3: Standard models are for BSL-2 experiments. For BSL-3 viruses, we offer customized models with negative pressure and exhaust HEPA filters, compliant with CDC guidelines.
