Thermometer Adapter
This is my first thermometer adapter. I have been doing chemistry for years but never bothered doing things that required monitoring the temperature
of a distillation, until now.
How do I use this? How do I get the thermometer inside it? Do I break the center of the plastic O-ring? I do not want to break something without
knowing I should. It will be difficult to find a new one and have it shipped from China.
If I use this one enough I will upgrade to a full glass version.

Thermometer goes trough the middle of o-ring, and the cap screws the o ring on adapter.
I guess your o-ring doesn't have hole, so you make one.

Run out to the hardware store and get several O rings. They will break, as chemicals attack them over time.
Phlogiston manufacturer/supplier.
For all your phlogiston needs.

Can I get any O-rings that can stand up to nitric acid?

Glass, completely sealed and a cheap thermocouple/thermometer (like the tm-902c) make a nice combination

Viton o-rings will hold up to nitric acid and many things that destroy EPDM o-rings. They however, will not hold up to many other things in the lab
like methanol, glacial acetic acid, ammonia, ether, or acetone.

I think at that point I will just buy a glass adapter, they are not much.

Hmm. Do you mean this kind?

We used to call such an item, "a thermometer well".
Sealing should no longer be an issue.
