• Made of regenerated cellulose
• Product Type: RC Tubing, Pretreated
• Length: 33 ft
• Diameter (mm): 11.5
• MWCO (Dalton): 3,500
• Manufacturer number: 132590
• Part Number: AO-02901-30
• Package Quantity: PACKAGE

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. More specific retentivity than SPECTRA/POR 1-4 membranes. Supplied wet in 0.1% sodium azide solution. Rinse before using. Contain heavy metal and sulfur traces. Pack contains 33-ft of membrane.
