Butane transfer to small bottle

[Paul06]

Hot water poured over the larger cylinder and the smaller cylinder cooled.

Heater blanket and weigh scales...

I would hope not!
Filling lighters seems to involve a lot of leakage in % terms.

It's the same ( all be it on a larger scale) as filling a cigarette lighter.

I never seem to get much gas transferred to a cigarette lighter or my gas soldering iron.

I’ve seen so many people try and do this with the lighter or iron on top and wonder why they only get a bit of gas transferred

It will also help if the lighter / soldering iron is cooler than the gas cannister.
Gas won't flow from a cool cannister into a warm lighter or iron because the pressure difference will be the wrong way round.

It's a slightly different situation.
The lighter starts off containing air or gas at ambient pressure.
The butane has a vapour pressure of over 2 bar at 20 degC, so there is plenty of pressure to push liquid butane into the lighter until it's about half full.

At this point, there's usually enough leaked butane evaporating from the lighter to chill it, so more liquid can be pushed in.

All definitely an outdoor sport!

This video is quite good for understanding the principles if not the technique.
