Superior Flow Control and Other Benefits

  • Precise, accurate flow control
  • Peristaltic-based, closed-loop with integrated flow sensors
  • Completely pulse-free flows
  • Fast response time and excellent stability
  • Unlimited fluid reservoir volume
  • Forward and reverse flow modes
  • Ability to dispense from, and recycle precious fluids back to the same reservoir
  • No need to recalibrate, even after changing tubes
  • Ideal for stop-flow experiments


Available in Four Models

  • Nano   20-7000 nL/min
  • Micro   0.1-50 microL/min
  • Milli   30-1000 microL/min
  • Milli+Five   0.2-5.0 mL/min


How it Works

A microprocessor rapidly adjusts the rpm of the peristaltic wheel, based on the flow sensor data, to provide a pulse-free fluid delivery.

Integrated Components for Each Fluid Channel
  • Peristaltic-wheel
  • Flow sensor
  • Controller
Communication
  • The integrated microprocessor reads the real-time flow rate measurement from the flow sensor, and then adjusts the rpm and direction of the peristaltic wheel to provide the desired flow rate.
  • The communication time is nearly instantaneous resulting in pulse-free, high performance fluid delivery.
Control
  • PC Software - Synchronize one to eight independently controlled fluid channels.  Fully programmable fluid delivery.
  • LabVIEW VI
Data Logging
  • Flow rate is logged.
  • Digital output via USB.
