In the "floating piston" design, the pistons and cylinders are fitted individually in such a way that the gap between them is just a few micrometers wide. This gap is filled by the fluid being dispensed, forming a zero-wear sealing system with outstanding sliding properties. Optimized flow channels make dispensing and priming even easier – particularly in instruments with large volumes.

Autocalvable at 121 °C. Easy to calibrate and adjust in order to comply with ISO 9001 and GLP guidelines. Replaceable filling and discharge valve with safety ball. Telescoping filling tube adjusts to different bottle sizes. Easy to dismantle for cleaning. The valve block can be rotated 360° so that the bottle label always faces the user for safety. The 45 mm standard thread plus the included adapters fit common lab bottles. DE-M marking.
