ReaXus LS Class

High Performance Isocratic Pumps

The reliable ReaXus LS Class consists of single-headed, positive displacement piston pumps incorporating advanced cam designs for very low pulsation.

The pumps are ideal for a wide variety of HPLC applications (including Biocompatible separations), Semi-Prep LC, metering & dispensing, and general laboratory use. Standard fluid path materials are Stainless Steel. Other available features include jacketed heads for temperature controlled processes. With 10 mL/min, 40 mL/min, and 100 mL/min versions available, and pressure capability up to 6,000 psi, these versatile pumps will meet the most demanding applications.
