The versatile LD Class consists of dual-headed<\/strong> HPLC Pump, designed as a positive displacement piston pump<\/strong>. It delivers unmatched performance for analytical, flash, and small-scale preparative chromatography applications. Designed for high flow rate accuracy and low pulsation, the LD Class meets the stringent requirements for Analytical Liquid Chromatography (HPLC).<\/p>\n

Standard fluid path materials include Stainless Steel and PEEK, in addition to optional Hastelloy. 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.<\/p>\n

The high-performance linear cams and automatic pressure compensation delivers precise flow rates for both high- and low-pressure gradients. Standard features also include an integrated Prime-Purge Valve, Pulse Dampener, interactive keypad control, and complete PC control and status monitoring through RS-232 and Micro USB 2.0 ports. The LD Class dual-headed HPLC pump provides the precise flow and low pulsation needed for even the most challenging separations.<\/p>\n
