Laf Bench

These test are executed on laf work bench.

Laf bench. Air velocity measured at 4 corners of the laf as shown below and recording shall be done at v1 v2 v3 and v4 calculate the average velocity. Depending on its design a horizontal flow hood provides protection. A laf bench is an important tool in many laboratories. Biological safety cabinets class 2 mars the mars is a series of dual filter class 2 cabinets which incorporates the latest in laminator technology energy saving designs and hepa filtration with options that give the best protection for you your products and your laboratory.

Vertical laminar flow clean benches. It is a must for work in a completely sterile environment and ensures the best protection possible for both user and product. Clean benches only provide product or sample protection while class ii biosafety cabinets also protect the bsc user and the environment both within the laboratory and in the community. Laminar flow hood also called a clean bench is an enclosed box that is designed to create a particulate free horizontal or vertical laminar airflow environment preventing airborne contamination of particle sensitive objects such as laboratory samples or semiconductor wafers.

The flow can be horizontal blowing parallel to the work surface or it can be vertical blowing from the top of the cabinet onto the work surface. This is the class ii bsc as specified in the european standard en 12469 and the class ii type a2 bsc as specified in nsf ansi 49 yy 0569 and other standards. A laminar flow cabinet or tissue culture hood is a carefully enclosed bench designed to prevent contamination of semiconductor wafers biological samples or any particle sensitive materials. Labflex can offer a broad range that meets the newest safety and ergonomics requirements in full and is simultaneously user friendly and easy to clean.

Vertical laminair flow sterile cabinet fortuna clean bench the fortuna is a series of vertical sterile laminar airflow cabinets which incorporate the latest laminator technology and energy saving designs with hepa filtration and a range of options that gives optimal protection of your product samples or equipment. Due to the direction of air flow the sample is protected from the user but the user is not protected from the. Laminar flow hoods protect the working environment from dust and other airborn contaminants by maintaining a constant unidirectional flow of hepa filtered air over the work area. Air is drawn through a hepa filter and blown in a very smooth laminar flow towards the user.
