LD Class HPLC Pump
Dual Piston Pumps for Low Pulsation Requirements
The versatile LD Class consists of dual-headed, positive displacement piston pumps, delivering unmatched performance for analytical, flash, and small-scale preparative chromatography applications. With the patented SSI low dead-volume Pulse Dampener, advanced cam technology and dual piston mechanism, the LD Class provides virtually pulse-free operation.
The pumps are designed for high flow rate accuracy and low pulsation required for Analytical Liquid Chromatography (HPLC). Standard fluid path materials are Stainless Steel and PEEK. Other available features include Hastelloy fluid path with jacketed pump heads for temperature controlled processes. With 12 mL/min, 36 mL/min, and 100 mL/min versions, reaching pressures up to 6,000 psi, these pumps will meet the performance requirements of demanding HPLC needs.
The high performance linear cams, along with automatic pressure compensation, provide precise flow rates for very accurate high pressure and low pressure gradients. Standard features include an integrated Prime-Purge Valve, Pulse Dampener, interactive keypad control, and complete PC control and status through RS-232, Ethernet, and Micro USB 2.0 ports. The LD Class provides the precise flow and low pulsation for the most challenging separations.
