The Spectra Por Spectra-Por SP-4 Dialysis Tubing is a cost-effective solution for gentle molecular separation in laboratory applications. Made from regenerated cellulose (RC), this tubing offers a molecular weight cut-off (MWCO) of 12,000 to 14,000 daltons, ideal for purifying proteins, enzymes, and other solutes. Similar to Spectra/Por 2 membranes but with a thicker wall, the SP-4 series provides slower dialysis rates at a significantly lower cost—ideal for routine, high-volume, or budget-conscious lab work. With a 45mm flat width and 28.6mm diameter, this 100-foot tubing roll is perfect for medium to large-scale sample processing.
