Open-Source Syringe Pump
Description
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 Sketch for Arduino, assembly and operating instructions are available at http://www.mass-spec.ru/projects/diy/syringe_pump/eng/ STL-files of case are available at: https://www.thingiverse.com/thing:4194107 The following video shows how the syringe pump works: https://youtu.be/0KjniIBHNMo A detailed description of the open-source syringe pump is presented in the following article: Samokhin, A.S.
