After the experiment is completed the pure caffeine that is left is from isolating compounds from natural sources. The purpose of this experiment was to learn how to purify compounds as well as isolate compounds based on certain techniques. Caffeine, an alkaloid which acts as a stimulant, was isolated from the natural product of tealeaves whether is be solvent extraction/isolation and or sublimation. By completing these steps the impurities of the original caffeine is being left behind and giving a more accurate and more pure substance of caffeine. Although in order to get the pure substance of caffeine, the chamber is highly dependent on vapor pressure inside and outside the glass. This can characterize the caffeine extracted from the tealeaves
