Level of Caninsulin vial

Hi
Please can somone tell me how full a brand new 2.5ml vial of Caninsulin vial should be ? Or post a photo of a new 2.5ml one showing the level if easier.
I have a "never used" one in the fridge and when I just looked at it the level is nowhere the full mark not even the 2/3rds mark. So i don't know if that's normal or something has gone wrong with it - no sign of any spillage and the cap has never been breached.

This is only the second vial I've ever had and I can't remember how full the first one was when new.
Thanks

 

It's probably pretty right. I have ProZinc which is also a u40 insulin. I started using this one a few days ago and so this is a pretty much full vial and you can see where it is.
