单柱塞泵系列，流速准确，适用于要求的HPLC应用。

The reliable LS Class consists of single-headed, positive displacement piston pumps incorporating advanced cam designs for very low pulsation.  With micro-stepping motor technology and a proven single-piston pump mechanism, the LS Class exceeds the performance of more expensive units at a fraction of the cost.

The pumps are ideal for a wide variety of HPLC applications (including Bio-compatible separations), Semi-Prep LC, metering & dispensing, and general aboratory use.  Standard fluid path materials are Stainless Steel and PEEK, n addition to optional Titanium. Other available features include jacketed heads for temperature controlled processes.  With 5 mL/min, 10 mL/min, 40 mL/min and 100 mL/min versions available, and pressure capability up to 6,000 psi, these versatile pumps will meet the most demanding applications.

Features include automatic pressure compensation, Pulse Dampener, integrated Prime-Purge Valve, interactive keypad control, and complete PC control and status through RS-232 and Micro USB 2.0 ports. The unique LS Class provides the highest performance/cost ratio in a compact package.
