Polyester (PET) is a hydrophilic membrane with good temperature resistance (up to 140 ° C) and a semi-translucent color.
Its chemical resistance is very high and in the case of biological sample filtration it is characterized by very low non-specific adsorption of proteins (<5 μg / cm2 of bovine serum albumin).
It is supplied in various pores of 0.22 μm and 0.45 μm; And in 25 and 47 mm in diameter.
