SpectrPor® Dialysis Tubing and Membranes

Repligen’s SpectraPor® membranes offer the largest selection of molecular porous dialysis tubing and membrane products to meet the diverse requirements for a myriad of dialysis applications.  Only Repligen provides dialysis membrane in Standard Grade and Biotech Grade, as well as 2 polymer chemistry-types, Regenerated Cellulose (RC) and Cellulose Ester (CE).

Since all “Standard Grade” Regenerated Cellulose (RC) membrane is produced by an industrywide process that introduces trace levels of heavy metals and sulfide impurities, these economical and versatile membranes are intended for general and less critical applications in which these impurities are negligible. Only Repligen’s SpectraPor Standard Grade RC membrane is available in 3 treatment types and 2 configurations for both lab-scale and large volume dialysis:

Standard RC Dialysis Tubing - Dry (SpectraPor® 1-5)
Economical for general and multi-use applications

Standard RC Dialysis Tubing - PreWetted (Spectrapor® 6)
Ready-to-use for out of the box convenience

Standard RC Dialysis Tubing - PreTreated (Spectrapor® 7)
Processed to minimize membrane impurities

Standard RC Single-layer membrane - Dry
(SpectraPor® 1-4) 

Sheets and discs for use with dialysis systems and assay kits

Repligen’s high purity Biotech Grade dialysis membranes are made in a cleanroom environment using a proprietary process free of sulfur compounds and heavy metals.  Since they do not contain trace levels of these impurities and do not need special cleaning or treatment, Biotech Grade membranes are preferred for more critical lab-scale  and GMP dialysis applications.  Biotech Grade Dialysis Tubing is available in 2 cellulosic polymer types: Cellulose Ester (CE) and Regenerated Cellulose (RC)
