Hi everyone,
What is a cheaper alternative to a rotovap?
Glassware with magnetic stirrer
thank you.
can you recommend the best way to decrease the pressure in the flask?
thank you.

Easiest 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.
thanks guys. could you say more or less what level of negative pressure is needed in the flask when trying to mimic a rotovap?
