The LS Class of single-headed, positive-displacement piston pumps (photo) feature very low pulsation and high accuracy, along with micro-stepping motor technology and a proven single-piston pump mechanism. Standard fluid-path materials are stainless steel and polyethertherketone (PEEK), with optional titanium components available. Also available are jacketed heads for temperature-controlled processes. Three versions are available, capable of handling 5, 10 and 40 mL/min, respectively. With pressure capability up to 6,000 psi, these pumps are suitable for a wide variety of uses, including biocompatible separations, semi-prep liquid chromatography, metering, dispensing and general laboratory use. — Scientific Systems, Inc., State College, Pa.
