How does a multi-port syringe pump + selection valve (e.g., J-KEM suite) combo work?

Nice to see the use of servos to control standard three-way valves (i.e., no differences in chemical compatibility with the automated system) in this recent article:

Also nice that they validated it with a bimetallic (Co and Ni) synthesis workflow with characterization afterward.

Hoping to see a video: Possible to see video? · Issue #1 · Materials-Informatics-Group/Robot_FLUID_3D-Parts · GitHub

EDIT: here’s a short video of the system (one syringe pump, I think the second from the right) in action:
