Lab Equipment: Glass Ampoules

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.

Very useful indeed, but how do you get it back out? I'm sort-of a beginner...

[NurdRage]

@firewing33 you score the glass with a file, and then snap it off.

[derflop]

does that complex contain a molybdopterin by any chance?

[NurdRage]

@derflop it contains a molybdopterin-like site, but its not true molybdopterin. Its more of a fluorinated bis-dithiolene with an additional thiolate ligand.

but by using this method the air that is trapped inside the vile will contaminate the chemicals

[NurdRage]

@Forget29it replace the air with an inert gas before stealing.

in fact.....there is an app for that :)

@wingchangwow that's some good shit yo

[pielover8888]

@StivenAliaj ... wa--wa--what? XD

[TimKa928]

@NurdRage just curious, what is it used for??

[AfroSamuraiTheMaster]

damn i wish this guy was my chemistry teacher

[michael1234252]

hey can you make a video explaining the science behind the Steel ball in aerosol cans like in spraypaint

[mynameismatt2010]

@NurdRage I hope you mean sealing.

[wingchangwow]

shit, 70,000$ a gram

[crazy4lego]

@NurdRage and that... made me realize that i'm very, very, stupid.

Great lab tip, really very helpful. :D
