ImOutAlsothank you.

can you recommend the best way to decrease the pressure in the flask?

thank you.

mithyl2Buchner flask with plug. Important fact that you have to use borosilicate glassware. The best way to decrease the pressure is vacuum pump. Providing and application of vacuum in a laboratory

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.

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

mithyl2Depends on solvent, temperature and vacuum.

Look up charts on google.
