Single piston pump with flow rate 0.01 – 10 ml/min and limit of pressure 40 (20) MPa is suited for washing process of chromatographic columns in liquid chromatography. It is designed with piston diameter of 1/8”.

Quite new concept of electronic and pump drive allow to use it as standalone unit, just as in PC controlled systems. New piston suspensions and its easy replacement prolong working life and simplify maintenance.

Intuitive operating using simple keypad allow easy functions chosen:

-  flow rate

-  maximal flow rate- PURGE ( for priming and washing)

-  display brightness

LED display allows to watch (also from a distance) adjusted flow rate. By pump function choosing, give you this display enough of information for adjusting.

By work with buffered solvents is possible to use pistons back washing.
