Overview#

The goal of this project is to provide an open-source syringe pump that is easy to procure and assemble, significantly less expensive than commercial pumps, while maintaining a sufficient level of dispense precision and accuracy. It was developed in the Karpova Lab at HHMI's Janelia research campus.

Features#

  • Infuse and retract
  • Limit switches
  • Spring loaded clamps provide secure holding while also allowing syringes to easily be swapped in and out
  • Small footprint (330 mm x 140 mm x 100 mm)
  • Can be mounted vertically or set horizontally on surface
  • Electronics designed to be modular
  • Assembly time < 15 minutes
  • Cost ~ $200
  • Open source, so you can modify the designs to fit your needs and make improvements!
