SPECTRA/POR tubular membranes are available in a variety of nominal molecular weight cutoffs (MWCO) and carry practically no fixed charge. Use SPECTRA/POR 1-4 membranes for separations at an approximate molecular weight cutoff. Supplied dry, they contain 10% glycerol, 0.1% sulfur, and heavy metal traces (except where indicated). Wash with distilled water first. Use SPECTRA/POR 6 and 7 membranes for separations at a specified MWCO. Supplied wet in a 0.1% sodium azide preservative solution. Order tubing closures seperately. For separations that require specific retentivity and are sensitive to sulfur and metals. EDTA-treated membranes contain no heavy metal traces or sulfur. Supplied wet in 0.1% sodium azide solution. Ready for use after rinsing and conditioning in dialyzing buffer. Each box contains 16-ft of membrane.
