hi i was just wondering how long can one bottle of 12 litre trimix last you?
It depends a lot on the mixture. If you have a 12 litre bottle of 10/70, and breath it at 20 feet or shallower, it'll last you the rest of your life....
By the same token, a bottle of 16/50 dived to 300 feet will last you the rest of your life, too.

Actually jokes apart, helium will slowly escape through the sides of the tank, so an unused bottle doesn't last for ever.
