thank you.

can you recommend the best way to decrease the pressure in the flask?
mithyl2Easiest method to control vacuum pressure in my opinion is with a vacuum gauge (negative) which means it reads from right to left (athmospheric pressure has to be taken into account)

And a globe valve, because they are very delicate in adjustment.
