haha actually its impossible/impraticle to clamp everything. Just make sure everything can hold safely then we will just leave it. In this case, we have a B14 ground glass joint from the flask holding the cold finger, so clamping the round bottom flask neck actually holds the cold finger quite nicely(by gravity lol).
The thermometer is somewhat hanging haha, but I used to take it away once the temperature is stable.
Its true that lab safety is important XDD
