Cellulose acetate is a hydrophilic material and with very low nonspecific adsorption of proteins. These characteristics make it suitable membrane filtration in the case of biological samples.
It is also recommended for use in the filtration of aqueous samples, most alcohols, oils and hydrocarbons.
It is available in pores of 0.22 to 5.0 microns and diameters from 13 to 293 mm in diameter.
