I prepare trimix in a 15L or 20L tank and then use a booster to refill my 3L tank. I was wondering if there is some issues with storing trimix for few months. If the tank is never moved over time could we get some kind of gas separation du to the difference in weight.(Helium find itself at the top close the valve since it is lighter) Should I give it a good shake, roll before using it to refill.
Would appreciate your views on the subject.
The only problem I had was he lost because of leak in some point: it so easy with he.

Well, off course after long periods some stratification is possible and shake the tanks can help you.
Hope this help.
Which booster are you using?
OOps, sorry, I forgot to have a look at you web page!

wouldn't of thought that it would be that much of a problem over a couple of months
It has happened to me over the course of days. Bottom line is the obvious; analyze ones gas.

the gas doesnt stratify once its mixed... brownian motion solves that. It can layer if you mix it VERY slowly, but a quick tumble will resolve that.
Thanks to all for your reply, which confirm my thoughts.
