The glass bulb electrode is an order one century old tool. I thought this question would have been answered quickly. Instead even with a little bit of an imitation of a bounty dance, zero nibbles.

Is there anything I can do to improve its chances of this getting some kind of an answer? What might the problems be with the question such that it might be off-putting to those that have some knowledge?

Am I looking for an answer that's too vague or imprecise? I'd even take a good reference in lieu of a detailed answer. So far when I pull books of library shelves they seem to tiptoe around these details. Maybe I don't know the right books?

All suggestions welcome!

    $\begingroup$ I think there is not much to do. You certainly did your homework, I mean research, and the question itself is well received. It may just be that no-one (here) has the time or knowledge to answer it. Sometimes it just takes more time. Don't give up just yet. $\endgroup$

  • $\begingroup$ It's actually a really complex question. When there's a pH difference across a glass membrane, it develops a measurable and repeatable potential difference. Why that potential develops.... if the answer is in the literature, it's in very old literature, and it's a phenomenon that's been "known" for so long that few people alive likely even know the full explanation. I agree with @Martin-マーチン, give it time -- the answer will probably be forthcoming eventually. $\endgroup$

  • $\begingroup$ "Durable" is a questionable term, I would argue. pH probes are ultimately consumables, just with fairly long lifetimes in most circumstances. As well - "host of other measurements"? Such as? In most other glass-bulb probes I know of, the bulb is highly porous, and is basically serving as a hollow frit. $\endgroup$

  • $\begingroup$ Are you sure? There's a whole raft of ion-selective electrodes that use a lot more than just a glass bulb. Why would people have made these if a pH electrode would have worked for the purpose? I'm interested to read more about them if they do exist, though. $\endgroup$

  • $\begingroup$ @hBy2Py OK this is interesting. I'm going to clean up some of these comments (this is not meta related), do some further reading, then ask a question about this. I'll let you know when I post it. Thanks! $\endgroup$

  • $\begingroup$ @hBy2Py OK thanks for the encouragement. Once I started reading about the glass bulb electrode I just became really intrigued by it. $\endgroup$

Per @Martin-マーチン's comment:

Sometimes it just takes more time. Don't give up just yet.

Indeed, a cyclohexane molecule has just posted a very helpful answer and discussion of the glass membrane. OK it wasn't an actual molecule that wrote the post, but the user @a-cyclohexane-molecule.

The answer was definitely worth the wait! +n!
