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, PEEK, and optional Hastelloy, with an additional option for Titanium. Other available features include jacketed heads for temperature-controlled processes. The dual-headed piston 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, these pumps will meet the most demanding LC and process needs.
Features include an integrated Prime-Purge Valve, interactive keypad control, and complete PC control and status monitoring through RS-232 and Micro USB 2.0 ports. The PR Class provides the flow rates and pressures required for high throughput separations.
