The rugged PR Class features dual-headed, positive displacement piston pumps that deliver highly accurate flow rates and excellent pressure capabilities. This makes them suitable for a wide range of applications.
Standard fluid path materials include Stainless Steel, PEEK and optional Hastelloy, with an 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, 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.
