It has two pistons connected in parallel, with diameter of 3/8”. It is suited for preparative liquid chromatography where is high pressure needed, etc.. Advantage of this pump is a very stable run even at low flow rates.
This pump is designed as stand alone unit.
There is a possibility to use this pump in a high pressure gradient mode, where two, three or four units are controlled via PC using RS232.
Control board is mounted at the unit back side therefore the installation is very easy. Just connect power voltage and RS232 and the pump is ready to go.
When working with buffered solvents, it is possible to use pistons back washing.
Pump is supported with software ECOMAC and Clarity.
This pump does not have a pressure sensor.
