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.

Customized Dialysis Membranes

While off-the-shelf rolled dialysis tubing may be suitable for the occasional research or analytical dialysis, many multi-batch dialysis applications require frequent routine processing and handling of dialysis membrane to prepare it for a particular use or assembly step. A customized dialysis membrane designed to fit your specific application saves processing time, minimizes handling, streamlines assembly production and reduces manufacturing costs.

Pre-cut Dialysis Membrane

Dialysis tubing and 1-ply membrane can be pre-cut into discs, sheets, strips or squares ready for assembly into assay kits, ready-to-use devices or dialysis apparatus.

Pre-rolled Dialysis Membrane

Dialysis tubing and 1-ply ribbon can be provided as a specified rolled length. For convenience, dialysis tubing closures can be applied and included within the individual pouches.

Pre-sterilized & GMP Packaging

Dialysis tubing and 1-ply membrane can be batch pouched and packaged for GMP; and pre-irradiated to minimize the risk of microbial contamination during use.

Let Repligen prepare, cut and package the dialysis membrane to meet GMP and application specific requirements for your batch dialysis; or tailor cut large quantity single layer membranes for diagnostic assay kits and multi-chamber dialysis systems.
