In this video we make glass ampoules.
Vials are great for storing chemicals, but sometimes you want greater long-term assurance against air or contamination. A flame sealed glass ampoule is the way to do this. Because it's a totally sealed glass container, unless it cracks, it better protects the contents against the environment than a vial. To use them you crack them open. They're not reusable but the protection they give is worth it for certain chemicals.
Usually you have to buy empty ones separately but you can make small ones from pipettes by simply flame sealing one end and then adding your chemical. You then flame seal the other end and now you have a simple glass ampoule. Be sure to check for cracks, if there are, you'll have to retrieve the chemical and try again with another pipette.
