These filters with cellulose acetate membrane whose main properties are: low absorption and non specific adsorption of proteins, and their high flow rate. All these properties make them very valid for the filtration of aqueous samples and biological samples.
These syringe filters are available in a sterile format ( individual blister) and non sterile, in pores of 0.22 and 5.0 μm and in dimensions of 13, 25 and 30 mm of diameter.
