Chemical reagents are relative standard materials for chemical research and component analysis. There are as many as tens of thousands of kinds, and they are mainly stored in suitable reagent bottles. Due to the differences in the performance of various chemical reagents, bottles are also different in appearance and color. Brown is one of the common container colors.[ Reagent Bottles 250ml Factories,Reagent Bottle 1000ml Suppliers,Wholesale Narrow Reagent Bottle,Pharmacy Reagent Bottle Factory ,Narrow Reagent Bottle Factories ]
The materials of the reagent bottles are mainly plastic and glass, and the colors include white, transparent and brown. Different from ordinary bottles, brown bottles are mainly used to store chemical reagents that are easy to decompose, volatilize, sublime or react with light when exposed to light. This is because brown can prevent visible light from being irradiated and prevent decomposition and deterioration of reagents. Common reagents stored in brown bottles include the following:[ Reagent Bottles 250ml Factories,Reagent Bottle 1000ml Suppliers,Wholesale Narrow Reagent Bottle,Pharmacy Reagent Bottle Factory ,Narrow Reagent Bottle Factories ]
1. Iodine: Iodine, No. 53 of the periodic table of elements, is located in the periodic table of the chemical elements in the ⅦA group of the periodic table of the chemical elements. It is one of the halogen elements. Iodine is easy to sublime. Iodine vapor itself has a pungent smell and is toxic. After the sun is exposed to the temperature, it is easy to sublime, so it should be placed in a brown bottle that is protected from light.
2. Silver nitrate: Silver nitrate is a colorless crystal, easily soluble in water. Pure silver nitrate is stable to light, but because the purity of general products is not enough, its aqueous solution and solids are often stored in brown bottles.
3. Chlorine water: Chlorine is an aqueous solution of chlorine gas with a molecular formula of Cl2 and a molecular weight of 70.91. Saturated chlorine water is light yellow-green and has a pungent odor.
4. Silver bromide: light yellow powder, photosensitive, insoluble in water and most alcohols, slightly soluble in ammonia. See the light to decompose metallic silver.
The brown reagent bottle is the color masterbatch added to the production raw materials, which changes the original color of the bottle. These reagents that are easy to decompose when exposed to light are stored in the brown bottle to ensure the stability of the reagent.[ Reagent Bottles 250ml Factories,Reagent Bottle 1000ml Suppliers,Wholesale Narrow Reagent Bottle,Pharmacy Reagent Bottle Factory ,Narrow Reagent Bottle Factories ]
