In laboratories where researchers handle sensitive biological materials, safety and cleanliness are paramount. A biological safety cabinet (BSC) plays a vital role in creating a sterile working environment while protecting users and samples from contamination. This article explores the main functions of biosafety cabinets, compares them with similar equipment like laminar flow hoods, and introduces key design innovations such as LCD control panels and advanced filtration systems.
The Function of Biosafety Cabinets
Biosafety cabinets are enclosed, ventilated laboratory workspaces engineered to contain airborne particles and protect the user, the environment, and the product. Unlike a laminar flow hood, which only provides product protection by directing filtered air across the workspace, a BSC also ensures operator safety by maintaining inward airflow and filtering exhaust air.
The function of a biosafety cabinet is threefold:
Personnel protection – preventing exposure to infectious agents.
Product protection – maintaining a contamination-free work area.
Environmental protection – filtering out contaminants before air is recirculated or exhausted.
Inside the HEPA Filtered Cabinet: Core Technologies
One of the core features of a biosafety cabinet is its HEPA filtration system, which removes 99.995% of particles as small as 0.3 microns. The featured 700 model includes dual ultra H14-grade HEPA filters with 70% recirculated and 30% exhausted airflow, achieving ISO Class 5 cleanliness levels. Its average front air intake speed of 0.55 m/s ensures effective barrier protection.
The work zone, made of 304 stainless steel, is corrosion-resistant and easy to clean, reducing contamination risks during sample handling. A 10W UV lamp and dual LED lighting provide both sterilization and high visibility.
Intelligent Design: LCD Control Panel and Customization Options
What sets this cabinet apart from traditional models is its instrument-style display panel, which includes controls for airflow, lighting, sterilization, and filter life monitoring. Time-controlled sterilization enhances laboratory safety and efficiency.
Additionally, the biosafety cabinet can be customized with a 110V power supply and U.S.-standard plug at no extra cost for small orders. This makes it a highly flexible solution for international labs.
