Dissolve it in dilute aqueous NaOH, filter and precipitate it by adding dilute (1:1) HCl. The process is repeated twice more, and the fluorescein is dried at 100o. Alternatively, it has been crystallised from acetone by allowing the solution to evaporate at 37o in an open beaker. It has also been recrystallised from EtOH and dried in a vacuum oven.
