Dual Piston Pump for low pulsation requirements
The versatile LD Class features dual-headed, positive displacement piston pumps. This dual piston pump delivers outstanding performance for analytical, flash, and small-scale preparative chromatography applications.
Designed for high flow rate accuracy and low pulsation, the LD Class meets the strict demands of Analytical Liquid Chromatography (HPLC).
Standard fluid path materials include Stainless Steel and PEEK, with optional Hastelloy available. Jacketed heads are also offered for temperature-controlled processes.
The pumps are available with flow rates of 12 mL/min, 36 mL/min, and 100 mL/min, and can handle pressures up to 6,000 psi, making them ideal for high-pressure HPLC applications.
