PREPARATIVE HPLC PUMPS Is a series of three pumps with a flow-rate range up to 50, 250 and 300 ml/min. These pumps work as isocratic pump and together with Gradient Box also as gradient pump.
ECB2007, ECB2007PC (ECB2005, ECB2005PC) Gradient Box is equipped with four way gradient mixing valve and must be ordered together 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”. New sophisticated unit allows achieving a precise low-pressure gradient, i.e. gradual changes of solvent composition by mixing up to four liquids at the pump’sentry. 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 back washing of pistons (e.g. when using buffered mobile phase).
Pump is supported by ECOMAC and Clarity software.
All pumps are delivered with GFP (PTFE) seals a default, recommended optimal seals are UHMW-PE seals, ask for more information.
