Molecular/Por Stirred Cells


Biologically inert, Molecular/Por Stirred cells are ideal for performing simple laboratory ultrafiltration applications. While nitrogen gas, air or additional solution is applied under pressure via a top fill port to drive filtrate through the Molecular/Por UF membrane, the membrane retains and concentrates larger molecular species in the reservoir chamber. By operating the Stirred cell on a magnet stir plate, a reciprocating magnetic stir bar suspended above the membrane minimizes concentration polarization and maintains effective filtration. A pressure relief valve ensures safe operation if pressure increases above a set limit. Molecular/Por Stirred cells are available in three volume sizes: 10 mL, 70 mL and 400 mL.


Quick and easy, leak-proof assembly.
Incorporated magnetic stirrer minimizes concentration polarization.
Clear reservoir chamber for sample visibility.
Pressure relief valve to reduce excess pressure.
