Glass Conical Flask 250ml | Measuring Flask, Molecular Flask, Erlenmeyer Flask, Chemistry Flask

Product Information

The final two attributes of Erlenmeyer flasks make them especially appropriate for recrystallization. The sample to be purified is heated to a boil, and sufficient solvent is added for complete dissolution. The receiving flask is filled with a small amount of solvent, and heated to a boil. The hot solution is filtered through a fluted filter paper into the receiving flask. Hot vapors from the boiling solvent keep the filter funnel warm, avoiding the premature crystallization. This standard was published in 2015 and supersedes the 2004 version. International standards are reviewed every five years, with this standard reviewed and confirmed in 2020.
