LABORATORY REAGENTS ACCORDING TO SCIENCE LABORATORY TESTS AND STANDARD PROCEDURES
Laboratory reagents Laboratory reagents are substance used to carry out a laboratory test. They can be classified based on: Purity. Technical Grade Chemicals: used for low-grade applications like commercial or industrial purposes. Due to the present impurities, it isn’t utilized for drug, food, or medicinal purposes. Synthesis Grade Chemicals: The primary purpose of this involves organic synthesis and preparative tasks. Lab Grade Chemicals: found in educational or teaching labs. Though their purity levels are high, the precise impurity levels remain anonymous. AR grade Chemicals: These are used for high precision work since trace impurities are restricted to the lowest possible limits for high precision. Such reagents get used mainly for analytical applications, research, and quality control. General Reagent (GR): reagent that meets or exceeds AR grade specifications. Extra Pure Grade Chemicals: suitable for laboratory acc...
