How to sort reagent bottles by cap type

Chemical reagent refers to an element or compound of varying degrees of purity used in chemical experiments, chemical analysis, chemical research, and other experiments. A reagent bottle is a special container for all kinds of reagents. According to the type of bottle cap, it can be divided into the following two types:
Grinding Flasks: Glass vials containing chemical reagents should be tightly closed. If you are using a three-glass bottle, the friction may increase as the mouth of the bottle dries out. It increases the fit of the bottle mouth and cap, but it’s not easy. ample. It’s hard to loosen, so a natural seal is good. Therefore, the bottles are used to hold the chemical reagents to be installed securely and to prevent the reagents from escaping or entering the air. Only when using alkaline sodium salt solution on a glass bottle will the scratched glass bottle cap stick to the neck of the bottle. This is because silica ions and hydroxide ions in the glass react to form viscous sodium silicate (commonly known as water glass). It is an adhesive.
Screw Top Bottle: Refers to reagent bottles with screw caps. The caps of these containers are generally made of polypropylene material by injection molding. The cap has a thread and matches the thread on the neck of the bottle. It achieves a good seal.
In terms of bottle cap types, reagent bottles can be divided into two categories above. There are many types of chemical reagents. Some are very stable at room temperature and others are very bright. Some are difficult to deteriorate in high temperature environment, and some are flammable. They are explosive and different reagents have different storage requirements. By acquiring the characteristics of each reagent and selecting the appropriate container, you can ensure stable reagent storage and achieve accurate and reliable experimental results.
