ECP2300 Preparative Pump

300ml/min 15MPa

Preparative HPLC pump with a flow-rate range up to 300 ml/min. 

Part number

This pumps work as isocratic pump and together with Gradient Box also as gradient pump.

ECB2005 (ECB2005PC) Gradient Box is equippedwith four way gradient mixing valve and must be orderedtogether with the pump.

These pumps are suited for preparative applications in liquid chromatography. There are designed with main and auxiliary pump heads connected in parallel with a piston diameter of 3/8”. Newsophisticated unit allows achieving a precise low-pressure gradient, i.e. gradual changes of solvent composition by mixing up to four liquids at the pump’s entry. It is also possible to predefine percentage of composition when using the pump in isocratic mode. The gradient profile can be defined from computer or manually using display and keypad. There are many improvements which make pumps more reliable include a new learning algorithm for pulsation suppression; leakage sensor etc.

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.
