- What existing solutions/examples have you implemented or heard about?
- How is the movement of the (usually working) electrode in and out of the electrolyte handled?
- How are automated electrical disconnects and re-connects handled, if at all?
- How do you approach liquid handling for hazardous materials (e.g., KOH) which can also be at high temperatures? (e.g., materials used, safety / robustness / cost)

The ability to handle hazardous materials depends on the materials used to construct the reactor. Most reactors should be capable of this, especially those made with PEEK. However, high-temperature reactions are more challenging, as they often require reactors made from stable, heat-conductive metals like titanium. This can introduce risks such as metal contamination in the reaction and metals are usually electrical conductive. So, we typically use PEEK, although it is unsuitable for high-temperature reactions. Recently, Kelvin and I have been discussing materials that are non-Econductive, thermally conductive, and chemically resistant for reactor construction—Kelvin might have some ideas on this.
