This pump works as isocratic pump and together with ECB2004B, ECP2004BP (ECB2007, ECP2007PC) Gradient Box with Degasser (without Degasser) also as gradient pump.
ECB2004B, ECP2004BP (ECB2007, ECP2007PC) Gradient Box with Degasser (without Degasser) is equipped with four way gradient mixing valve and must be ordered together with the pump.
With a flow-rate of 0.02-10.00 ml/min. and a pressure limit at 40 MPa is this pump suited for analytical applications in liquid chromatography. It is designed with main and auxiliary pump heads connected in series with a piston diameter of 1/8”
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’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 a computer or manually using display and keypad.
There are many improvements which make pump more reliable, safe and precise. Also, maintenance is now easier. E.g. pistons exchange is easier because of new construction; 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.
