This is about 9 grams short. How did you tell the scales the tare weight of the cylinder?

I tared the scale with an empty one (or maybe not totally empty to your point).

That'd account for it. Interested to hear what the difference between the empty cylinders is. It's normally stamped on the side.

Emptying one of these to a pure vacuum or even close is going to have God, Boltzmann and the FBI knocking at your door demanding an explanation. And Boltzmann has been dead for 116 years.

There is absolutely no way a soda stream bottle weighs only 9 grams. Probably at least 35-50g.

The full bottle weighs approx 6.6 lb or 3kg or 3000g. Just the gas weighs around 400g.
