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

A detailed description of the open-source syringe pump is presented in the following article: Samokhin, A.S. Syringe Pump Created using 3D Printing Technology and Arduino Platform. J Anal Chem 75, 281–287 (2020). https://doi.org/10.1134/S1061934820030156

UPDATE (09 Dec 2023): the ‘carriage_lm8uu.stl’ file is added. When using standard linear bearings (i.e., LM8UU instead of LM8SUU), the bearings do not extend beyond the boundaries of the 3D printed carriage.
