Preparative LC systems

HPLC pumps K-series

K-100

K-series pumps are designed for preparative chromatography employed worldwide for simple and demanding applications. K-prep series dual reciprocating and the high precision servo motor enable highly-accurate pumping with less pulsation.

Features
  • A wide range of flow rates and range allow a minimum flow rate 1/1000 of the maximum.
  • Usable as a high pressure mixing gradient system by adding on a sub-pump.
  • Gradient and flow rate programmable provided by microcomputer control
  • Max. pressure limit can be set enabling column overpressure protection.
  • Plunger wash ports (optional) to prevent salt deposition and premature seal failure
  • Explosion proof pumps (optional) available
