Our open-source syringe pump incorporates a microcontroller controlled stepper motor turns a lead screw that pushes or pulls the plunger of a syringe. All black pieces in the photo are printed using our 3D printer. Rails are 8 mm hardened stainless steel. The carriage that secures the syringe plunger rides on linear bearings to provide smooth action.
Electronics and Software
Syringes are held by a separate fitting piece that can be easily changed. To change the syringe, loosen the two screws on the front of the syringe mount and the one on the top of the carriage and lift the syringe and syringe holder from the pump. Syringe holders can be custom printed to fit syringes up to ~20 mL. Files are available for you to custom print your own, or we can do that for you. The pump comes with holders that fit 1, 3 and 10 mL Beckton-Dickinson plastic syringes.
