Open-Source Syringe Pump

thingiverse

This open-source syringe pump has been designed for use in an analytical laboratory setting. Since 2014, many open-source projects of syringe pumps have been developed. Our project stands out with several key features:\r\n\r\nA universal clamp allows installing various syringes (diameter up to 25 mm) with ease.\r\n\r\nAll parameters (including the inner diameter of the syringe, flow rate, target volume and time) can be changed using the control panel, which includes multiple buttons and a two-line display. No computer connection is required for this functionality.\r\n\r\nInfusion, refilling or continuous (cycle) modes are available for use with our pump.\r\n\r\nDispensing accuracy and reproducibility are comparable to those of commercial syringe pumps.\r\n\r\nUnits of volume, flow rate and time can be changed as needed.\r\n\r\nIllegal input values caused by discrete rotation of the stepper motor are rounded to the nearest allowed value for accurate measurement.\r\n\r\nAll settings are stored in non-volatile memory for secure retention.\r\n\r\nAssembly takes several hours and requires almost no soldering, making it a relatively simple process.\r\n\r\nSketches for Arduino, assembly instructions and operating guidelines can be accessed at http://www.mass-spec.ru/projects/diy/syringe_pump/eng/\r\n\r\nSTL files of the case are available at: https://www.thingiverse.com/thing:4194107\r\n\r\nA video demonstrating how the syringe pump works is accessible at: https://youtu.be/0KjniIBHNMo\r\n\r\nA detailed description of the open-source syringe pump can be found in the article "Syringe Pump Created using 3D Printing Technology and Arduino Platform" by Samokhin, A.S., published in J Anal Chem 75, 281–287 (2020), available at https://doi.org/10.1134/S1061934820030156.
