Classification of chemical reagents according to the label of the reagent bottle
A chemical reagent is a special solution, which is a relative standard substance for chemical research and component analysis, and is stored in a special reagent bottle. Borosilicate Glass Media Bottle,1l Media Bottle,Blue Screw Cap Media Bottle,There are many types of chemical reagents. In order to facilitate the distinction, labels of different colors are usually posted on the bottle body.
Generally speaking, the color of the label on the chemical reagent bottle mainly has four colors of green, red, blue, and yellow, which respectively indicate the following meanings:
Green label: pure superior grade, belongs to the first grade, is used for precision analysis test, can be used as a reference substance. The main component content is very high and very high, which is suitable for accurate analysis and research work, and some can be used. Expressed in GR.Borosilicate Glass Media Bottle,1l Media Bottle,Blue Screw Cap Media Bottle
Red label: Analytical pure, belonging to, being, slightly lower, and impurity content slightly higher than excellent grade pure, suitable for important analysis and general research work, such as common reagents in general laboratories, research institutes and other places. Expressed in AR.
Blue label: chemically pure, it belongs to the third grade, and the label is medium blue, which is used for low-demand analysis experiments and high-demand synthesis experiments. Expressed in CP.
Yellow label: experimentally pure, belongs to the fourth grade, the label is yellow, the main component content is high, the purity is poor, the impurity content is not selected, and it is only suitable for general chemical experiments and synthetic preparations. Expressed in LR.
Chemical reagents have different properties, some of which are flammable, explosive or toxic. The labeling of different colors on the reagent bottles is also for the classification and management of different reagent types to ensure the safety of the experiment to a greater extent.Borosilicate Glass Media Bottle,1l Media Bottle,Blue Screw Cap Media Bottle
