danymal - If the ampules are 10 mg/ml, 50 mg/ml or 100 mg/ml, the concentration will remain the same regardless of what size vial you put it into. Your total mg will increase depending on how many ampules you transfer into the vials.
uglyass is right, they sell/describe the vials by volume, I am not sure what you mean by 100 mg/10 ml vials?
Hopefully this is just a semantics issue bro, but if you don't have it straight, make sure you do before you transfer.
