micro-Controlled Flow – Syringe Pumping System
We present an open source micro-controlled syringe pumping system. Describing how to build from scratch the mechanical layout, the electronics for manual control, the micro-computer programming and the remote control procedure.

The final cost is very affordable and will save about 75% on commercially available devices with comparable features.
Performance is checked and it presents a syringe resolution of 0.004% respecting the nominal syringe volume, accuracy of 0.03% and relative standard deviation (RSD) below than 2% over the whole range of flow.
When two syringes of 10 mL are used, the flow range goes from 7.72 mL/s to 0.26 µL/s.
Look here for documentation and technical files: Schematics and PCB designs, masks for PCB photoetching, blueprints of parts, bill of materials, STL files for 3D printing, assembly drawings and more.
A communication protocol is implemented allowing USB remote control and fully programmable operation: linear flow gradients and complex sequences, multiple pumps control for continuous flow or mixtures of fluids, and more.
All programming tools used in this work are Free Software.
