The rugged PR Class consists of dual-headed positive displacement piston pumps that provide high accurate flows and excellent pressure capability for a variety of uses.
The rugged PR Class consists of dual-headed positive displacement piston pumps that provide high accurate flows and excellent pressure capability for a variety of uses. Standard fluid path materials are Stainless Steel and in addition to optional Titanium. Other available features include jacketed heads for temperature controlled processes. The pumps are designed for a wide range of Preparative and Semi-Prep Chromatography as well as SMBC (simulated moving bed chromatography) and many process and industrial applications. With 100 mL/min and 300 mL/min versions reaching pressures up to 4,000 psi the pumps will meet the most demanding LC and process needs.
