  2. Laminar flow cabinet - Wikipedia

    en.wikipedia.org/wiki/Laminar_flow_cabinet

    Preparation of microbiological samples in a laminar chamber. A laminar flow cabinet or tissue culture hood is a partially enclosed bench work surface designed to prevent contamination of biological samples, semiconductor wafer, or any particle-sensitive materials.

  3. Filtration - Wikipedia

    en.wikipedia.org/wiki/Filtration

    A partial vacuum is typically provided to the container below the filter media when laboratory filtration is challenging to speed up the filtering process. Depending on the type of filter being used, the majority of industrial filtration operations employ pressure or vacuum to speed up filtering and reduce the amount of equipment needed. [5]

  4. Microfiltration - Wikipedia

    en.wikipedia.org/wiki/Microfiltration

    These systems are compact and possess a sturdy design, Compared to cross-flow filtration, plate and frame configurations possess a reduced capital expenditure; however the operating costs will be higher. The uses of plate and frame modules are most applicable for smaller and simpler scale applications (laboratory) which filter dilute solutions ...

    A column of HEPA filtered, sterile air is also blown downward, over products and processes to prevent contamination. Air is also exhausted through a HEPA filter, and depending on the Type of Class II BSC, the air is either recirculated back into the laboratory or pulled by an exhaust fan, through ductwork where it is expelled from the building. [9]

  6. HEPA - Wikipedia

    en.wikipedia.org/wiki/HEPA

    HEPA filters are designed to arrest very fine particles effectively, but they do not filter out gasses and odor molecules. Circumstances requiring filtration of volatile organic compounds, chemical vapors, or cigarette, pet or flatulence odors call for the use of an activated carbon (charcoal) or other type of filter instead of or in addition to a HEPA filter. [20]

  7. Schlenk-frit - Wikipedia

    en.wikipedia.org/wiki/Schlenk-frit

    A Schlenk-frit is a laboratory filtration device operating under inert gas conditions (schlenk conditions). It separates air- and water-sensitive suspensions into liquid and solid parts. A Schlenk-frit is made of a glass tube with a ground glass joint at both ends, a fused filter (a porous glass disk) and valves at both sides. [1]
