Chemical reagent is the necessary solution in the laboratory and has different characteristics according to different types, such as inflammable, explosive, oxidation, toxicity, easy decomposition of light, etc. Therefore, so there are a wide variety of reagent bottles used for storing reagents. Due to the various characteristics of chemical reagents, a little carelessness is easily causing safety accidents, so the reagent bottle should be paid attention to the following problems when using.

1. Laboratory personnel should be familiar with the properties of the most commonly used reagents, and pay attention to protect the label of the reagent bottle, so as not to confuse the reagent type;

2. In order to ensure that the reagent is not contaminated, the reagent should be removed from the reagent bottle with a clean corner spoon, and the reagent should not be poured back into the original bottle;

3. Do not use the nose to aim at the mouth of the reagent bottle to inhale, if you need to smell the smell of the reagent, the bottle mouth away from the nose, with the hand above the reagent bottle, so that the air blows to yourself and smell the smell, it is strictly prohibited to taste the reagent with the tongue;

4. In summer volatile reagent bottle is not easy to open, the bottle can be soaked in cold water for a period of time, to avoid the danger caused by the impact of air-liquid in the bottle at high room temperature, after the century to cover the plug, release toxic, smelly gas bottle also use wax sealing;

5. Waste reagent bottles should not be discarded at will, and should be treated centrally after washing.

The above are some matters needing attention in the use of reagent bottles in the laboratory, the safety of the laboratory not only needs to pay attention to the use of reagent bottles, in the experiment all kinds of subtle things should be carefully handled, to avoid the occurrence of safety accidents.

Disposal of waste reagent bottles:

1. Reagent bottle recovery requires a clean, clear label, and no residue;　　

2. The laboratories and scientific research institutions shall develop special reagent bottle storage places, and record, store and recycle the used reagent bottles uniformly;

3. Before recovery, the reagent bottle should be cleaned, and the waste liquid generated by flushing out the toxic and harmful reagent bottle shall be recycled according to the laboratory waste liquid recovery method;

4. When the reagent bottle is accumulated to a certain number, then it is transported to the reagent bottle recovery place for centralized treatment.

It is the common responsibility of every laboratory and scientific research institution to formulate a corresponding management system for discarded chemical reagents and reagent bottles and do a good job of treatment to prevent secondary pollution to the environment.
