Dosing systems


A series of  Microdosing-Pumps with high accuracy cover almost all metering applications in the laboratory. Different control systems from a basic analogue controller up to a programmable microprocessor control unit are available.
Various types and sizes of pumpheads, with and without rinse port, afford dosages from 1 µl up to 400 ml/min.

The Multi-channel pump “Tower II” is developed for special dosing tasks in laboratory and Pilot-Process applications.

Another specialty is our „Pulse-free“ range of pumps, a further development of the HPLH pumps for applications where a pulsing flow of a common piston pump will disturb.

For customers who wish to build their own dosing station we provide OEM components and assemblies consisting of pump modules, controller boards, operation units and/or remote controllers.
