GE Healthcare's Regenerated Cellulose Membrane by Cytiva

Flexibility is one of the key criteria requested in filter media used for chromatography sample preparation and solvent preparation. Users expect solvent compatibility, robustness, low protein binding, filtration efficiency, purity, and a choice of pore sizes.

In response to these requirements, Whatman developed the Regenerated Cellulose (RC) membrane which enables customers to select one membrane for a wide range of applications. This filter media is based on a cellulose acetate membrane and is therefore hydrophilic.

Additional production steps create a highly resistant pure membrane that is compatible with a number of solvents including acetonitrile, methanol, and tetrahydrofuran.

So if you are currently using PTFE media for solvents and a cellulose acetate based membrane for aqueous solutions, please try the Whatman RC membrane which will offer you greater flexibility in your day-to-day tests.
