Single piston pump with flow rate of 0.02-10.00 ml/min and limit of pressure at 40 MPa is suited for columns washing and columns regeneration process in liquid chromatography. It is designed with piston diameter of 1/8”.
This pump may be used in classical analytical applications where pulsation does not matter.Pulsation can be eliminated by pulse dampers.
Completely new concept of electronic control and drive of pump allows using it as standalone unit, as well as in PC controlled systems.
OLED display allows to watch (also from a distance) actual pressure or flow rate settings.When working with buffered solvents, it is possible to use piston back washing.
Intuitive operating using simple keypad allows easy selection of functions for both pump version:
maximal flow rate - PURGE (for priming and washing)
