Column Chromatography → An analytical technique which separates mixtures based on their distribution between a stationary liquid phase and a moving gas phase.
Fractional Distillation → useful to separate two liquids w/ vastly diff. boiling points at least 20 degrees C.
Desiccator → container that can be sealed from the atmosphere and holds a drying agent
Recrystallization → Separation technique used to purify particles of interest from a mixture of solids. Mixture is dissolved in saturating amounts in warm solvent. As the solution cools, the pure substance crystallizes while impurities remain in solution.
