Chemical reagents are the basis for conducting various chemical experiments, and the stability of reagents is related to the safety of experiments. There are thousands of chemical reagents in various forms and performances. How to judge the stability of the reagents in the quality Plastic reagent bottle?

To determine the stability of a substance initially, the following principles can be followed:

1. Inorganic compounds: as long as they are properly kept and the packaging is intact, they can be used for a long time. However, those substances that are easily oxidized and deliquescent can only be stored for a short period of time (1 to 5 years) under dark, cool and dry conditions, depending on whether the packaging and storage conditions of the quality Plastic reagent bottle meet the regulations.

2. Organic small molecular weight compounds: generally have strong volatility, and the airtightness of the quality Plastic reagent bottle is better and can be stored for a long time. But it is easy to be oxidized, decomposed by heat, easy to polymerize, photosensitive substances, etc.

3. Organic macromolecules: especially living materials such as oils, polysaccharides, proteins, enzymes, peptides, etc., are easily affected by microorganisms, temperature and light, and lose their activity, or deteriorate and spoil. Therefore, they should be stored in cold storage (frozen), and The time is also shorter.

4. Reference materials, reference materials and high-purity materials: in principle, they should be stored in strict accordance with the preservation regulations, to ensure that the packaging is intact, to avoid being affected by the chemical environment, and the storage time should not be too long. In general, the reference substance must be used within the validity period.

On the whole, the effectiveness of the quality Plastic reagent bottle depends on the nature of the reagent itself, combined with the preservation of the reagents in the quality Plastic reagent bottle to make an apparent observation, and then make a conclusion on whether it can be used according to specific needs.
