SpectraPor® 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).

SpectraPor® Pre-wetted Standard Grade RC Dialysis Tubing and Trial Kits
Repligen provides a pre-wetted option for Standard Grade Regenerated Cellulose (RC) dialysis tubing for ready-to-use convenience, suitable for the same dialysis applications. Pre-wetted dialysis tubing eliminates the preparation time required to hydrate the membrane and removing glycerin.


SpectraPor® 1-5 Dry Standard Grade Regenerated Cellulose (RC) Dialysis Tubing & Trial Kits
Repligen’s Standard Grade Regenerated Cellulose (RC) membrane is available as dry rolled tubing as an economical and versatile option for general dialysis applications in which there is a significant size difference between the molecular weights of the species being separated.

SpectraPor® Biotech Grade Cellulose Ester (CE) Dialysis Membrane
Repligen produces molecular porous Biotech Grade Cellulose Ester (CE) membranes in a large range of MWCO’s specifically for critical MW separations using a proprietary casting process free of heavy metal and sulfur contaminants. The CE dialysis tubing is ultra-pure and does not require special cleaning or treatment.

SpectraPor® Biotech Grade Regenerated Cellulose (RC) Dialysis Membrane
Molecular porous Biotech Grade Regenerated Cellulose (RC) membrane is produced for more challenging lab-scale dialysis applications that require high molecular selectivity as well as a membrane with higher purity and compatibility to harsh conditions.
