An internal transducer provides pressure display and monitoring capability. The pump is also useful as a flow source when other pumping is not convenient or available. 


  • Digital stepper drive and rapid refill of
  • Wide flow range
  • Internal pulse diameter
  • Fully IC and biocompatible
  • Positive seal-washing standard to extend seal life by removing salts and wetting the seal
  • Flexible, advanced Chromeleon control (version 6.8 or later)
  • Integrated inection valve with a purge/priming port for precise flow or loop injections

Multiple Uses

  • Supply of cone wash solvents to keep the entrance orifice of the MSQ free of salt and matrix buildup, thereby increasing the time between required maintenance cleaning of the MSQ
  • Postcolumn addition pump for introducing organic additives or acid/base modifiers to the eluent stream, or reagents for the derivatization of analytes after chromatographic separation

Easy Maintenance

  • The complete head assembly can be changed in seconds at a price similar to seals and check valves in many pumps
