Quaternary Analytical Pumps

The Thermo Scientific Dionex UltiMate 3000 Quaternary Analytical Pump LPG-3400SD is the pump of choice for flexibility across a broad range of analytical LC applications, with the highest degree of choice in eluent proportioning and mixing. Up to four solvents may be used for convenient method development, system flushing, and solvent preparation.

  • Serial dual-piston operating principle, low-pressure gradient proportioning
  • Wide operating flow rate range from 200 µL/min to 10 mL/min with high flow rate accuracy
  • Support of operating pressures of up to 620 bar (9000 psi)
  • SmartFlow technology automatically ensures optimal chromatographic performance at any operation condition
  • Automatic compressibility compensation, no manual solvent setting needed
  • Unique SpinFlow™ mixing design perfectly balance gradient delay volume against mixing efficiency
  • Extensive mixer portfolio (35–1550 μL) to cover all application needs
  • Reliable vacuum degassing with an internal four-channel micro membrane degasser
  • Active rear-seal wash for maximum seal lifetime, and reduced instrument down time

The LPG-3400SD is ideally-suited for method development, as well as for analytical research and routine analysis in the pharmaceutical, food and beverage, and environmental industries.
