CP-SR Piston Pump

Powerful sampling pump for all semi-automated dissolution tester.

  • Universally deployable
  • Accurately delivers small to large volumes
  • Easily handles different media types including foaming media with surfactants
  • Pushes through filters with minimum porosities down to 0.2 microns
  • Allows for extremely short sampling intervals of less than one minute
  • Valve-free and self-priming ceramic piston head design requires only minimum maintenance
  • Stackable with other Xtend™ modules to save bench space


Filters with a minimum porosity of 0.2 microns for the filterstation dissolution tester USP 1256

Faster. Stronger. Better.

Immediately reaching up to 40 mL/min without priming, the CP-SR accurately delivers small to large volumes. Powerful and precise, the piston pump pushes through filters down to 0.2 microns.


Using identical components, the CP-SR is optimized for space-saving operation. The compact pump requires only minimum footprint and can be stacked with the SAM-SR to save bench space.
