I sometimes use my small scale more than the big one.I think the max I will mix will be 60 ml each time I only got a limit of concentrates first want to try them once I have the scale and maybe new nic cause I didn't kept mine in a fridge

As long as that batch of nic has not gone totally of colour and does not smell bad you can still use it, I never used to keep mine in the fridge but with the heat we have been having it oxidizes even while you are just mixing. Cool dark place is fine, fridge or freezer best. That’s where mine is now staying going forward.
