Why are reagent bottle made of glass?

Not all reagent bottles are glass. Bottles for Hydrofluoric acid are plastic-- it will eat through glass! Some Reagent bottles are polypropylene. The glass-stoppered ones that used to be some common in labs were because they didn't have the plastics they do now. Many nasty acids, like concentrated Nitric, will dissolve most bottle caps--rubber, cork, steel, etc. The loose ground-glass stoppers are inert to most acids and alkalies, and also don't contaminate the reagent. Picric Acid, for example, used to be readily available; it wasn't too corrosive but would produce a sensitive high explosive if exposed to copper and some other metals.


Using dark-colored reagent bottles in storing some chemicals?

This amber/brown color is one of many pigments that are used to prevent ultraviolet (UV) light from penetrating the chemical reagent's bottle and damaging a photosensitive chemical. While there are some molecules that are affected (often very little) by the visible spectrum of colored light, UV-light is the primary range of the electromagnetic spectrum that can catalyze unwanted reactions in bottles which effectively degrades the reagent.


Why is it important to use a clean and dry spatula in scooping solid chemicals from the reagent bottles?
