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® 1-4 Single-Layer RC membranes are available as pre-cut discs or large square sheets that can be cut-to-size for use in assembled flat-sheet dialysis systems (equilibrium dialyzer, microdialyzer and macrodialyzer) to study molecular affinity, enzyme activity and biochemical interactions.  Provided dry with or without glycerin, Standard Grade RC is a clear and flexible membrane that does not carry a fixed charge, exhibits low adsorption and contains trace heavy metals and sulfur compounds that can easily be removed (refer to User Guide).  Standard Grade RC membrane has a good chemical compatibility with concentrated-weak or diluted-strong acids & bases, most alcohols and some organic solvents, while tolerating pH 2 - 12 and temperature 4 - 121° C. Compatibility to specific solvents should be confirmed on the Chemical Compatibility table.
