SUBLIMATION Sublimation is a technique used by chemists to purify compounds. Typically a solid is placed in a vessel which is then heated under vacuum. Under this reduced pressure the solid volatilizes and condenses as a purified compound on a cooled surface‚ leaving the non-volatile impurities behind. This cooled surface often takes the form of a "cold finger" (shown in the diagram above). Once heating ceases and the vacuum is released‚ the sublimed compound can be collected from the cooled surface

The Action of Naturally Occurring Toxins and Medicines It is important to classify toxins and medicines (drugs) in order to understanding the mechanism and function of each one of them. By doing so‚ it is also possible to increase their values by altering their mechanism (e.g. converting toxins to drugs) to cure diseases and improve human health. Therefore in this review‚ the mode of action of several toxins and drugs as well as their effects on human body will be discussed. 1. Cobratoxin Cobratoxin
