The 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 [1‑18]. However, this project has several features:
- a universal clamp allows installing various syringes (D ≤ 25 mm);
- all parameters (including the inner diameter of the syringe, the flow rate, the target volume and the time) can be changed using a control panel (which includes several buttons and a 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;
- an 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.
