Many of our kits include reagent bottles for steeping and storing bitters. This type of bottle has been used to store chemicals for at least 150 years, though the idea for the ground glass stopper dates back to the late 1700s. The combination of glass bottle and stopper makes the container very resistant to chemical corrosion with a few exceptions. Very strong alkali should not be stored in these bottles because the alkali can cause the stopper to corrode and fuse to the neck of the bottle. Also, hydrofluoric acid should never be stored in glass containers because it will actually dissolve the glass.When pouring hot liquids into a reagent bottle or placing the bottle in the refrigerator, the lid should be propped open with a toothpick or other small object until the liquid and bottle are cool. Another way to seal the bottle while preventing the lid from sticking is to place a sheet of plastic wrap loosely over the bottle neck before pushing the stopper down.Reagent bottles are labeled using a system which includes a "hybrid" hazard labeling system.Laboratory bottles and jarsWhen you're trying to decide on the right kind of packaging and bottles for your product, it's important to know exactly what you’re getting, and what to expect.
