LU Class 5 mL/min Flow Rates for Accurate Pressures up to 18,000 psi

The analytical LU Class consists of dual-headed, positive displacement piston pumps, delivering accurate flow rates at extremely high pressures. Available fluid path materials are Stainless Steel and Titanium for standard and Bio-compatible UHP chromatography applications.

The LU Class is designed for fast, high pressure analytical HPLC, with increased peak resolution and exceptional retention time repeatability. The SSI advanced solvent select feature provides very accurate flow rates at high pressures for a wide variety of solvents, particularly where compressibility is a major factor. Pressure capability is 18,000 psi, with a maximum flow of 5 mL/min.


  • Max. Flow and Pressure Ratings: 5 mL/min (18,000 psi)
  • Pulsation: ±0.75% from 3,000 psi to 18,000 psi
  • Pressure Accuracy: ±2% of full scale pressure
  • Flow Resolution: 0.001 mL
  • Flow Accuracy: < ±1% at 1 mL/min, 5,000 psi with Methanol
  • Flow Precision: 0.5% RSD on > 30 sec. average flows
  • Jacketed heads for temperature controlled processes
  • Automatic pressure compensation
  • Pulse Dampener
  • Integrated Prime-Purge Valve
  • Interactive keypad control

With pulse-free performance and precise control, the LU Class provides the highest flow accuracy over the entire pressure range.
