Positive Displacement Pump

Providing laminar flow at sub-microliter to nanoliter dispense volumes.

Our custom anti-backlash mechanism prevents step loss and maintains its resolution, even after 1 million cycles.



  1. Three Moving Components 
  2. High precision, fine pitch lead screw
  3. Optical sensor
  4. Rotary encoder with over 4000 pulses
    per revolution


  1. Small volume dispense of 500 nL  
  2. Chemical inertness 
  3. Lowers cost of installation
  4. Pulseless “smooth” flow with up to 98% stability
