Chemists & Vets, I Need Help Transfering Oils!!!

Fellas, how do you transfer oil from a container to another sterile vial without contaminating the product? I plan on buying sterile vials from Researchkits.com. Do I need any other products for the transfer? This will be my first time doing this and I don't want to screw it up. I need a step by step guide to follow in as much detail as possible. Thanks for your help!!

I think CE pretty much said it all. the only thing i would add is to wipe down the septums (rubber stoppers) on the vials with 90% rubbing alcohol before you put the needle through it.
