View Chemical Reagent Types on Reagent Bottle Labels
Chemical reagents are special solutions that are relative standards for chemical research and compositional analysis, stored in dedicated reagent bottles. There are many types of chemical reagents, and bottles are usually labeled with different colors to distinguish them.
In general, the colors of the reagent bottle labels are mainly green, red, blue, and yellow to indicate the following meanings:
Green label: high-grade pure, first-class, used for precision analysis and testing, can be used as reference material. The main ingredient content is very high, suitable for precise analysis and research work, some are available. expressed as GR.
Red label: Analytical pure water, belonging to, slightly lower, with a slightly higher impurity content than high-grade pure water, suitable for important analytical and general research tasks, such as general laboratories, research institutes and other places where reagents are commonly used. expressed in AR.
Blue label: It is chemically pure and belongs to tertiary products, the label is medium blue, used for low-requirement analytical experiments and high-requirement synthetic experiments. It is denoted by CP.
Yellow label: laboratory pure water, belongs to the quaternary product, the label is yellow, the main ingredient content is high, the purity is low, the impurity content is not selected, only suitable for general chemical experiments and synthetic preparations LR.
Chemical reagents have a variety of properties, some of which are flammable, explosive or toxic. used and greatly guarantees the safety of the experiment.
