Supor® hydrophilic polyethersulfone membranes offer higher fluid flow rates, lower protein binding, lower extractables, and greater strength than other cellulosic (acetate, nitrate) membranes.

Provide some of the highest water flow rates and fluid filtration capacities of any membrane filter. These membranes are non sterile, except for 28147-979, which is gamma-irradiated.

The 142 and 293 mm discs feature printed tab for instant recognition of pore size and lot number.

Several of these membranes are offered as recommended replacements for the discontinued HT Tuffyrn membranes.
