 Preparative Gradient Pump LCP 50K

is a double-acting pulseless gradient preparative pump making possible to form up to ternary low pressure gradients of mobile phases with flow-rates ranging from 0,5 to 50 ml/min.
A maximum operation pressure of 28 MPa. The pump is equipped with electronic fuses which stop the flow when preset either maximum or minimum operating pressure limits are exceeded. When necessary it is possible to use back rinse of pistons (e.g. after using buffered mobile phases). Sapphire valves in a PEEK housing facilitate cleaning.
The programs controlling the changes in gradient composition during analysis may be stored in a memory. 
The start may be initiated either from keyboard or with a switch on an injection valve.
The unit can be controlled using keyboard and display or using RS 232.
