A clean bench is a closed laboratory bench designed to prevent contamination and pollution by controlling and maintaining air cleanliness at a certain level.A clean bench is a type of laminar airflow cabinet (also known as a tissue culture hood).Clean benches are commonly used in laboratories around the world in a variety of industries. These fume hoods feature state-of-the-art technology to provide a clean, safe,sterile environment for laboratories handling sensitive biological substances.The hood ensures that the operating environment is 99% free of 0.3 micron particles.
What is the function of the ultra-clean workbench?
Clean benches prevent airborne dust,fumes,bacteria,microbes, and other unwanted dirt from contaminating the biological material and samples laboratory workers are currently working on.A HEPA filter is a high efficiency mechanical filter that allows air to pass through, cleans the air and directs the airflow towards the material.Ultra-clean benches maintain a high level of air cleanliness even in heavily polluted environments.
Can ultra-clean workbenches also protect workers?
A clean bench only provides protection for the samples,substances and materials being handled as it directs filtered air across the work surface towards the worker.These covers can be used for specific cleaning operations,such as sterile facilities or dust-free assembly of electronic equipment.Clean benches should not be used when handling pharmaceuticals,highly infectious substances,or other hazardous samples.Laboratory workers are exposed to these substances,which may cause (depending on the material) poisoning,infection, contamination or toxicity.Therefore,ultra-clean benches should not be mixed with biological safety cabinets.
What are the different types of clean benches?
Circulation Station:This hood allows clean air to circulate.
Lightweight clean bench:the bench is made of glass or acrylic; moreover, it has fluorescent lights.
Drain Station:Workstation also includes sink with faucet.
Drying station:Infrared rays dry material quickly.
Built-In Bench:The floor-standing unit is built-in to the unit.
Exhaust station:Air can be extracted from the workstation or a portion thereof.
Anti-vibration workbench:The gap between the main unit and the workbench prevents the enclosure from vibrating.
