If you have a stirbar in the glass vessel, and if the temperature is controlled by the reading *inside* the vessel, no. Important is the mixing.
Without it, particularly if the vessel's contents are solid, you are of course in trouble.
For this reason, I adjusted the mantle voltage according to the temp reading inside the glass bulb, after letting the temperature stabilise for i.e.
15 minutes. Just use a voltage controller, and run a couple of trial series, at various voltages, and see where the beaker temperature settles. Volume
shouldnt be that much of an issue, as the mantle pretty much wraps around half of the beaker.
