n00b question about IV

[catnsdogz]

So there's a vendor that has something I have always wanted - morefine in an ampoule. It comes in 20mg/ml and they are 1ml ampules. 

I would personally think 5mg is more than enough for me but I want to be able to ensure the solution stays sterile.  

Could I buy a mixing vial and take the solution and dilute it with bactosteric water and then use a 1ml syringe to get 5mg? Would the leftover solution be sterile and if so how long is it good for.

Cheers

I would hope the amp would have a rubber poke through top. If not, I wouldn't know about keeping it sterile. If I were to acquire that amount, I'm sure one little vial wouldn't last long enough to matter. But I guess I never used to take enough precautions to keep things sterile. Spoons, tap water, and the occasional reused $yr!nge...I guess I should be glad I'm still here. Yesteryear was an uncautious time for me!
