These pumps work as isocratic pumps and together with the gradient box also as a gradient pump.

ECB2005 (ECB2005PC) Gradient Box is equipped with a four-way gradient mixing valve and must be ordered together with the pump. Also available in configurations made of certified bio-inert materials.

These pumps are suited for preparative applications in liquid chromatography. These are designed with main and auxiliary pump heads connected in parallel, with a piston diameter of 3/8 ”. This 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’s entry. It is also possible to predefine the percentage of composition when using the pump in isocratic mode. The gradient profile can be defined from the computer or manually using a display and keypad. There are many improvements that make the pump more reliable, including a new learning algorithm for pulsation suppression; leakage sensor, etc.

When necessary, it is possible to use back-washing of the pistons (e.g. when using buffered mobile phase).

The pumps is supported by ECOMAC and Clarity software. 

All pumps are delivered with GFP (PTFE) seals as a default, optimal recommended seals are UHMW-PE seals (ask for more information).

This pump is equipped with the Pressure Compensation Learning algorithm. Thanks to this smart adaptive process, the pump regulates the rotation speed of the camshaft and measures its impact on pressure pulsation to minimize the output pulsation as much as possible. The algorithm, due to its adaptive capacity, is applicable for many combinations of pump working conditions (solvents, columns, etc.).
