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® 1-4 Standard Grade Regenerated Cellulose (RC) Single-Layer Dialysis Membrane

Standard Grade Regenerated Cellulose (RC) Single-Layer Membranes are ideal for use in dialysis systems, dialyzer devices and assay kits.

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.

SpectraPor® Pre-treated Standard Grade RC Dialysis Tubing and Trial Kits

Repligen provides a high purity, clean Standard Grade Regenerated Cellulose (RC) dialysis tubing that has been pre-treated for more critical applications that could be negatively impacted by the presence of trace heavy metals, sulfur compounds and membrane adherent impurities.

SpectraPor® Standard Grade Regenerated Cellulose (RC) Customized Dialysis Membranes

Let Repligen customize and tailor Regenerated Cellulose (RC) membrane or tubing specifically for your batch dialysis to save production time and money, while minimizing risks for GMP process. You design, we make.
