Low-cost touchscreen driven programmable dual syringe pump for life Science ApplicationsValentina E. Garcia, Jamin Liu, Joseph L. DeRisi
Science Direct, 2018Abstract: Syringe pumps are powerful tools able to automate routine laboratory practices that other-wise consume large amounts of manual labor time. Commercially available syringe pumpsare expensive, difficult to customize, and often preset for a narrow range of operations.Here, we show how to build a programmable dual syringe pump (PDSP) that overcomesthese limitations. The PDSP is driven by a Raspberry Pi paired with a stepper motor con-troller to allow maximal customization via Python scripting. The entire setup can be con-trolled by a touchscreen for use without a keyboard or mouse. Furthermore, the PDSP isstructured around 3D printed parts, enabling users to change any component for theirspecific application. We demonstrate one application of the PDSP by using it to generatewhole cell lysates using a cell homogenizer in an automated fashion.
