Plastic Reagent Bottle is available in white and brown. Brown reagent bottles are used to contain reagents or solutions that are easily decomposed by exposure to light, such as iodine solution, silver nitrate, potassium permanganate, potassium iodide, etc.
There are two types of reagent bottles: ground and non-ground. Generally speaking, non-ground reagent bottles are used to contain lye or concentrated salt solution, etc., and rubber stoppers or corks are used to prevent the reagent from crystallizing or dissolving the glass, causing the stopper to stick to the bottle mouth and not easy to open. The ground bottle holds acid, non-strong alkaline reagent or organic reagent solution, and other substances that are less corrosive to glass. When using, pay attention to the original bottle with the original stopper, and the number of the bottle and the stopper should match to facilitate sealing, avoid solution evaporation and change the concentration.
When the reagent bottle is not in use, it should be cleaned, and a paper strip should be placed between the bottle mouth and the plug to prevent them from sticking to each other after being left for a long time. Reagent bottles can only be used to hold and store reagents, and cannot be used as heating vessels, nor can they be used to inject reagents that are suddenly cooled and hot, let alone prepare solutions and store concentrated alkali and concentrated salt solutions in the bottle. Reagent bottles have a large mouth and a small mouth. The large mouth is mostly used to hold solids, and the small mouth is used to hold liquids. Sizes range from 30ml to 20,000ml.
Steps for usage:
1. Select the appropriate volumetric flask.
2. Check whether the volumetric flask is leaking.
3. Pour a small amount of distilled water into the volumetric flask.
