is there a place to get a high heat thermometer?
Okay so im looking for a distillation thermometer that can fit into a distillation adapter. The problem is the thermometer that came with my glassware
only goes up to 150C and the highest ive seen online go up to 200C but dont alot of things boil way over that? I cant find any thermometers on ebay
that go up to like 300-450C. Is that normal? Is there a place that sells these? Or is it because most of the time when boiling things of that temp
your using a vacuum so you dont need to measure that high?

Digital stem thermometers reading 300 C are widely available.
McMaster-Carr has one with an 8" stem for $30:

If the stainless steel stem is too reactive for your needs, you can put it in a glass tube with a sealed end.

I guess you are referring to a liquid in glass thermometer. The alcohol in glass thermometers are limited to about 200C because of the limitation of
the alcohol.
Mercury in glass thermometers go to about 350C but they are being phased out in many countries and may no longer be sold to the public.
see: https://en.wikipedia.org/wiki/Mercury-in-glass_thermometer#P...
Depending the details of use 450C may be too high for your glassware.
There are a varity of different electronic thermometers that go to 450C or higher you will find them on ebay.

A thermocouple is the solution for very high temperature measurement. I have a K-type that goes up to 1350C! It's also able to record and output data
from two probes at once. Nice thing to have!
