The presented pH robot was designed and developed in-house. An assembly guided is provided in the ESI. A bill of materials (Supplementary Table ) for commercially purchased parts and 3d-printed parts (Supplementary Table ) can be found in the SI. Additionally, the CAD design files to 3d-print the parts can be found under the following GitHub repository: . This repository has the codes for the equipment firmware, as well as a main Jupyter Notebook to operate and run the pH robot, including the titration algorithm.
