You should use a graphite block to flatten the glass. Graphite is what glassblowers use to form the glass. And then you don't accidentally crack your beaker from heat shock.
@@juanignaciocaso4651 WTF are you talking about? You want him to press HOT glass into wet paper? Do you know what water does to hot glass if you let it sit there? Glassblowers have to CONSTANTLY SPIN glass on wet newspaper so that the layer of steam protects it. IF YOU KEEP IT STILL, IT EXPLODES IN YOUR FACE.
@@xz3693 It more just smoulders and catches fire, from my experience. But yeah, you do keep the glass in constant motion when forming in glass blowing, and drip on new water on the paper when time allows it.
so you can have a pure chemical of medicine you make without worry about it becoming contaminated while being stored until needed, or to make say, stink bombs
If you don't anneal the glass it might just randomly check(break) while sitting on your shelf. Its better to just leave a pinpoint hole at the top,anneal then fill with a syringe then seal it. As a side note graphite aluminum or brass will be a far more suitable material to press against. get/make a polariscope and look at your ampoule and you will see the stress lines in the glass.
Early wine bottles had the same issue when trying to stand up straight. A solution was found however and we now indent the bottoms of wine bottles to form a flat surface. So if you could find a small marble or something to form a little dome on the bottom it'd probably make your ampules a lot more stable and easier to form :)
Wine bottles have a dome shape to allow for pressure build up. More common in the past but still vital for sparkling wines. Using a small brass dome rivet in a hole in some brass plate might be the best way to form a dome and a flat rim. Using just the dome/marble will not make the rim level, just narrow. However the reason for the glass was low thermal conductivity so brass, copper and aluminium are bad, stainless steel if you must use metal but graphite is the material of choice for glass working marvers if you plan to make lots.
I used an ordinary propane torch and thick borosilicate test tubes. I was surprised to be able to store some bromine in such an ampule. And it didn't break even at room temperature.
I thought you was making god damn lightbulbs out of test tubes because ampoule means lightbulb in my language lmao, would b pretty cool to see in the future doe
The ampule would burst the instant it is fried, because the burning of the propellant would already be too much for it, rather check out how tranquilizer guns work.
+Santosh Samuel I was actually thinking about it. In the future I think I will do that, but for now I would like to work on getting all the experiments done that I want to do!
+NileRed question. how would you do this if your storing something that is flammable? or like how do they get things that are pyrophoric like cesium inside amples
Labs that use pyrophoric solids often use a glove box to handle them, other than that pyrophorics and other air sensitive reagents are normally bought as solutions and syringed to get it from stock bottle to a flask fitted with a rubber septum and flushed with an inert gas (N2 or Ar)
To make an ampoule with a 'scratch-zone' for safer opening! Like this: 1) Pull a short, fat neck (the scratch-zone) about 1/3 the way from the open end of the tube. B) Pull a longer slender filling-neck from about half of the pulled section from step the first, leave a 'bulb' between the two necks. Tube tube sealing end. By scratching the fat neck, a cleaner break is possible.
Perhaps flare the opening out like a martini glass before making the glass thinner to allow yourself a larger opening for material. I'm sure using a pipette would make this step unnecessary for some things but things like solids may benefit from this extra step
Nice video. A question: I would like to put in ampoules a dry salt and inside it I want a nitrogen atmosphere. Any suggestion? I was thinking about doing the glass heating and melting with a rubber septa and a needle that flushes nitrogen.
Steel is okay as long as it is cold. Yes graphite tools are incredible for doing lamp work but the majority of hot glass work is done with steel. If you need the metal to stick to the glass, heat it up. If you need it to not stick, keep it cold. Simple as that.
Brass also works well. When I started with glass work years ago I had a charred hardwood stick coated with beeswax as my main reamer before getting graphite tools
+Lajos Winkler Yeah i saw you last comment. I made the other video private because i forgot to originally do that. The twisting was definitely not good :)
this is really good!! just a question from an ignorant guy. you need o2 for fire right? if so, how do you put in the ampoules anhydrous reagents for INNERT atmosphere rxn. with no air getting inside the ampoule.
Actually opening an ampoule requires experience. The tip part should be broken, but sometimes the internal liquid generates gases that cause the entire ampoule to break. To prevent this, the ampoule should be cooled in a refrigerator to condense any possible gases and then just break the tip using small pliers.
Very old video but might as well still ask some questions to you who is a pro at this, just got 3 questions for you. 1. How would I seal something that reacts with air (Ex: Sodium) into an ampoule without tarnishing it (without professional equipment of course)? 2. How would I make a gas ampoule with something other than air (Ex: Hydrogen), and if you can how to do I make a gas ampoule glow near and electromagnet? 3. What about epoxy resin (for questions one and two)? I would like to end this comment with how much I love your videos and how they inspire my to pursue chemistry and make some really toxic stuff by accident 😅
I am making an element collection. Do you have any recommendation for any dangerous gasses or liquids, e.g. chlorine gas, that you would recommend making?
These often have a very high vapor pressure (e.g. diethyl ether) and sould be stored in a proper unbreakable bottle, not completely air tight but closed. Plus, they should be stored in a well ventilated area or under a fume hood.
I would say a propane torch could work, but wouldn't be ideal. You would likely have to heat the glass up with a kiln before using propane torch because the thermal shock would likely shatter your piece. You could try holding the glass far away from the torch to pre heat it, moving it very slowly closer to the hottest part of the flame. It would take much longer than the yellow tanks but would probably work.

That is very useful! You should do a series of videos where you make other pieces of useful laboratory glassware out if test tubes.

Nile Red Hmm, I always thought it was "ampoule", am I wrong?

Ah, it might be one of those annoying words with multiple spellings, suchas "sulfur" and "sulphur".

I had a couple pop on me too, just holding the amps back from the flame a few inches and cooling a little slower worked here.
I had the same thing happen. Need to _"flame seal"_ these bad boys! (Learned it on Codys Lab)
Thanks Nile Red, love your videos.
Excellent update, thanks.
Thank you! I’ve been searching for this forever! Thank god I found your channel!
Flat bottom ampoules aee a game changer, thanks Nile Red.
Concerning flattening, you could make a jig to constrain the tube vertically so that the bottom is consistently flattened.
Great idea! Or buy test tubes with flat bottoms to begin with.
Early wine bottles had the same issue when trying to stand up straight. A solution was found however and we now indent the bottoms of wine bottles to form a flat surface. So if you could find a small marble or something to form a little dome on the bottom it'd probably make your ampules a lot more stable and easier to form :)

However the reason for the glass was low thermal conductivity so brass, copper and aluminium are bad, stainless steel if you must use metal but graphite is the material of choice for glass working marvers if you plan to make lots.
Such ampoules are perfect to store air or moisture sensitive compounds, which usually sealed in controlled environment.

Major tip, wait until the chemical is completely cooled before testing the seal on the ampoule. Could avoid catastrophic failure in the glass.
