Syringe Pump

Features

• Infuse and retract capable syringe pump

• Frame is made of lasercut parts and standard hardware

• Small footprint (330 mm x 140 mm x 100 mm). Can be mounted vertically or set on surface

• Cost ~ $200

• Motor controller includes color display and joystick/buttons for manual control

Background

The goal of this project is to provide an easy to assemble, open-source syringe pump that is significantly less expensive than commercial pumps, while maintaining a sufficient level of dispense resolution and repeatability.

This is not the only open-source syringe pump that exists. Here are some other projects you may be interested in:
