Open-Source Syringe Pump

This open-source syringe pump has been designed for use in an analytical laboratory. Many open-source projects of syringe pumps have been developed since 2014. However, our project has several features:
- Universal clamp allows installing various syringes (D ≤ 25 mm)
- All parameters (including the inner diameter of the syringe, flow rate, target volume and time) can be changed using the control panel (which includes several buttons and two-line display); connection to a computer is not required
- Infusion, refilling or continuous (cycle) modes are available
- Dispensing accuracy and reproducibility are comparable to commercial syringe pumps
- Units of volume, flow rate and time can be changed
- Illegal input value (caused by discrete rotation of the stepper motor) is rounded to the nearest allowed value
- All settings are stored in non-volatile memory
- Assembly takes several hours and requires almost no soldering
