ECOM ECP2300 Preparative Pump with Pressure Sensor, 0.1 - 300 mL/min, 15 Mpa / 2250 PSI

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
