Product Description

By: The Flinn Staff


Caffeine is a naturally occurring heterocyclic molecule called an alkaloid. Alkaloids contain at least one nitrogen with lone pair electrons, giving them their characteristic basic property. Caffeine is found in the seeds, leaves, and fruits of many plants. In this lab activity, students first perform separation methods by extracting and isolating caffeine from tea leaves. Next, they calculate percent recovery and different student groups analyze the recovered caffeine for purity using different methods, including thin-layer chromatography (TLC), crystallization, and sublimination.

Includes reproducible student handouts, detailed background information, complete Teacher Notes with sample data, and all necessary chemicals and consumable supplies.

Complete for 30 students working in pairs. A short-wave UV lamp is required and available separately.
