After purification via extraction, any organic substance should be rigorously dried; otherwise, its further purification via recrystallization will often fail to achieve the desired result.  In a typical purification of an organic unknown, a solution of crude product in an organic solvent (i.e. diethyl ether) is what will remain following extraction.  Suggest a simple means to remove small quantities of water from this solution.
