With a flow rate of 0.01 – 10 ml/min and a pressure limit of 40 MPa, this pump is 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”. It has a high-performance processor unit and a three-way gradient valve. This allows the pumps to be used for creating a low-pressure gradient, i.e., gradual changes of mobile phase composition by mixing up to three 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 course can be defined either through the keypad or downloaded from a computer.
A quite innovative concept of electronic control, pump drive, piston suspension, cams shape, pressure transducer and check valves expand functionality and improve reliability as compared to the preceding LCP 4100 model.
The pump is equipped with electronic fuses which stop the flow when preset either maximum or minimum operating pressure limits are exceeded.
When is necessary it is possible to use back rinse of pistons (e.g. after using buffered mobile phases). Ceramic valves in a PEEK housing facilitate cleaning.
