Modular Open-Source Stirred Tank Reactor (MOSTR)

Overview

MOSTR (the Modular Open-Source Stirred Tank Reactor) is an IoT-enabled system developed for teaching chemical engineering principles such as residence time distribution, flow balancing and process instrumentation within higher education laboratories. Developed as a low-cost and pedagogically informed alternative to commercial units, the MOSTR’s modular design allows for the simultaneous deployment of multiple rigs to enhance student engagement and inclusivity in practical learning at scale.

Re-use or Adapt

This project has been designed to support wider adoption and adaptation by other educators and institutions. All components are designed to be fabricatable by readily accessible means, such as 3D printing and laser cutting, or easily sourced as low-cost off the shelf parts. Alongside the publication (as above), the associated files and resources have been made openly available to support reuse and further development across the higher education sector (click on the "access this resource here" button at the top of this page).

You can use this resource as-is for your own teaching or you can adapt it to suit your own needs, as long as the full terms of the relevant licence(s) are followed (see "Resource Info" on the right, or the above links for more details).
