Thin Layer Chromatography
Thin layer chromotography (TLC) is used to identify the composition of a small amount of sample and to help with choosing solvent systems for an extraction or chromotography
TLC Timelapse under UV
Column Chromatography
Rotatvap
A rotovap is used to remove excess solvent from a solution.
Extraction and washing - Workup
An extraction removes the desired compound from a mixture. A wash removes unwanted impurities from a mixture. "Keep the extract and trash the wash"
