Reagents are indispensable for any experiment, and the reagents not only have various states, but also the performance of different reagents varies greatly. Some of them are very stable at room temperature, some are usually very lively, some are not subject to high temperatures, some are flammable and explosive, some are strong and some are highly toxic. Only in-depth understanding of the relevant knowledge of chemical reagents can be carried out safely and smoothly. It can guarantee the achievement of the intended experimental purpose and eliminate the pollution of the aged environment. Therefore, we must first know the classification of the reagents. Then you can master the storage box of various reagents. and so. The preservation and classification of laboratory reagents should be paid attention to, so sloppy!

From the point of view of the storage and use of the reagents, the reagents are often classified by the method of classification and performance.

1. The classification method of inorganic reagents and organic reagents is consistent with the classification of chemical substances, which is convenient for identification, memory, and convenient for storage and retrieval. The inorganic reagents are classified into a large class according to simple substances, oxides, alkalis, acids, and salts, and then classified according to their properties. The organic reagent is classified into hydrocarbons, hydrocarbon derivatives, saccharide proteins, polymer compounds, indicators, and the like.

2. Classification of hazardous and non-hazardous reagents This classification not only pays attention to practicality, but also takes into account the characteristic properties of the reagents. Therefore, it is convenient for safe storage, and it is also convenient for the experimenter to observe the safe operation rules when using.

1. Classification of hazardous reagents; divided according to the nature of the hazardous reagents and storage requirements:

(1) Flammable reagents; such reagents refer to chemicals that are self-igniting in the air or that are likely to cause combustion in the presence of other substances. Due to the existence of the state or cause of combustion, it can be divided into: 1 easy to spontaneous combustion reagents: such as yellow phosphorus. 2 Water burning reagents: such as potassium, sodium, calcium carbide, etc. 3 Flammable liquid reagents: such as benzene, gasoline, etc. 4 Flammable solid reagents such as sulfur, red phosphorus, aluminum powder, etc.

(2) Explosive reagents; refer to chemical substances that are subjected to severe chemical reactions by external forces and cause combustion and explosion while releasing a large amount of harmful gases. Such as potassium chlorate.

(3) Poisonous reagents

Shanghai Jinma strictly controls the quality of products, and the inferior reagents often make the reliability of the experiment not well guaranteed. Therefore, the innovation and development of biological research reagents are accelerated, and the quality of scientific research reagents is comprehensively improved.
