Precision Fluidics Division

The Ultra Low Carryover valve technology is the optimum solution for meeting the rigorous demands of High-Performance Liquid Chromatography. Whether you are using a single solvent, dual solvents, or a quaternary approach, the ULCO family of valves will ensure that mixing is accurate and precise. The resulting gradient of eluent composition will increase selectivity, sensitivity, and accuracy for the separation and detection of a wide range of chemical compounds. Accomplished through a combination of fast and repeatable response times, extremely low internal volume, and an advanced well-swept design all in an industry leading miniature package size.

Features

  • Smallest 3-Way valve with this performance/footprint
  • <1.5 W Hold Power
  • Up to 45 PSI (3.1 bar) pressure rating
  • Low unswept volume to minimize carryover
  • 100% tested leak rate ensures a leak tight seal on every valve
  • CE, REACH, and RoHS compliant
