Regenerated cellulose membrane filters
Hydrophilic membrane compatible with various solvents including acetonitrile
See in the different catalogues:
The regenerated cellulose is a membrane with excellent resistance to temperature (up to 180 ° C) and outstanding mechanical strength.
Its chemical resistance is high (pH 3-12) and in the case of biological sample filtration it is characterized by a very low non-specific adsorption of proteins (<10 μg / cm2 of bovine serum albumin)
It is supplied in various pores of 0.22 μm and 0.45 μm; 25 and 47 mm in diameter.
