The reliable LST 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/LST Class exceeds the performance of more expensive units at a fraction of the cost. The pumpsa are ideal for a wide variety of HPLC applications (including biocompatible separations), semi-prep LC, metering and dispensing, and general lab use.
