Plastic reagent bottles and glass reagent bottles comparison
Reagent bottles are containers used to store various chemical reagents. According to different materials, they are divided into two types: glass material and plastic material. There are thousands of chemical reagents. So what is the difference between these two materials?
The raw materials of plastic reagent bottles are generally polyethylene or polypropylene, which can resist the corrosion of most acid and alkali solvents, and are light in weight and not brittle. Generally, solvents with no special requirements for materials can choose containers of this material, and the suitable PH value is 5.5 Solutions in the range of -9.0, but not suitable for strong oxidizing, strong acid and alkali liquid packaging, and not suitable for strong reducing liquid packaging.
The transparency of glass material is relatively high, but it is relatively easy to break and is not convenient for transportation. It can also be corroded by most acid and alkali solvents. However, the bottle containing alkaline substances or water glass must use rubber stoppers or cork stoppers, because these substances will It reacts with the silica in the glass, resulting in the adhesion of the bottle mouth and the bottle stopper, which is inconvenient to open and has certain dangers. The hydrofluoric acid solution is a corrosive reagent, which has a strong corrosive effect on glass. If inhaling the vapor or contacting the skin, it will cause incurable burns. You should choose a plastic reagent bottle.
At present, plastic material and glass material are still the main raw materials of reagent bottles. These two materials have certain complementarity in practical application and can meet the storage requirements of different chemical reagents.
