Continuous flow rate measurement without interference

The Biotech Flow Meter is specifically designed for continuous measurement of flow rate without interference in your fluidic systems. Compatible with all HPLC and GPC solvents, it is conveniently sized and powers itself from a USB connection. The current flow rate is displayed on the Flow Meter’s integral high resolution OLED Display, allowing easy control of current flow value. A PC based App allows continuous recording and storage of the measured flow rates.

Available in 4 different models to cover a wide range of flow rates:

  • Micro Flow: 10nL – 80mL/min
  • HPLC Flow: 1mL – 5mL/min
  • Prep Flow: 0.1mL – 40mL/min
  • High Flow: 0.1mL – 650mL/min

Application Areas

  • Chromatography – validation & diagnostic purpose
  • Peristaltic pump monitoring
  • Flow chemistry
  • Process flow applications

Product Features

  • Portable robust unit with 1μl resolution
  • Easy time factor selection
  • Connects to any LC chromatography instrument
  • Perfect for IQ OQ PQ qualification
