Scientific Glass Blowing Ep:4 How to make an ampoule from scratch or from test tube

SUBSCRIBE ► https://www.youtube.com/c/ProjectLosA... In today's video, we will be taking a look at making and sealing glass ampoules. If you are going to do chemistry, learning how to make an ampoule is something you need to know. Even if you only know one glass working technique, this is the one to know. Ampoules are the only way to store volatile chemicals long-term. Chemicals like bromine are notorious for their ability to leak out of any bottle, no matter how good the seal is. Other chemicals are reactive to the air, which leak into a bottle over time. If alkali metals are wanted to be stored, mineral oil will work. Even under oil, an oxidized surface will form, but storing it in an argon-filled ampule, the beautiful sheen of the metal can be preserved. An ampule can not only last years but centuries. eBay ► https://www.ebay.com/usr/wheelerscien...
