Johnson Test Papers offers a complete line of microfiltration products for laboratory applications including membranes and syringe filters.
Microfiltration is a type of physical filtration process where a contaminated fluid is passed through a special pore-sized membrane to separate micro-organisms and suspended particles from process liquid.
Sterile Membrane Filter
Membranes enable a very convenient, fast and economical separation for both liquid and air. Often they are used as a neutral sample support for further analysis.
Suitable choice for a wide range of applications such as basic research, environmental testing, cell retention, particle collection, clarification and sterile filtration of aqueous solutions, particulate analysis, microbiological analysis, epifluorescence microscopy, pharmaceutical as well as food and beverage industries.
