Tubular RC membranes are available in a variety of pore sizes with molecular weight cutoffs (MWCO) ranging from 1,000 to 50,000 daltons. Membranes are resistant to a wide variety of organic solvents, acids and bases. Available wet or dry in varying lengths and diameters.
Spectra/Por 1, 2, 3 and 4 are supplied dry and contain glycerol to retain moisture.
