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 an OEM 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.
When necessary, it is possible to use of back washing pistons (e.g. when using buffered mobile phase). Pump is supported by ECOMAC and Claritysoftware.
All pumps are delivered with GFP (PTFE) seals a default, recommended optimal seals are UHMW-PE seals, ask for more information.
Options on request:
- Control module for LAN and USB communication
- Pressure sensor
- Additional board for gradient valves controlling
