In the recrystallization procedure, an Erlenmeyer flask is commonly used during the step in which the crude is dissolved in the solvent of choice. Furthermore, if the recrystallization is slow typically the flask is closed with a cork. What do you think is the reason for using a cork and not a plastic stopper (which would seal the flask better)
