Glass rods are used in laboratories for scientific experiments in Chemistry, Biology and Physics with the purpose of spreading or pouring liquids uniformly into another object or onto something. They are often used because they are inert and therefore are good in stirring solutions or mixtures. Glass Rods are also used when dealing with toxic chemicals thus are helpful in protecting one from being hurt or injured.
