Draw from vial one. Do NOT pull the plunger any farther. Air will make this process harder. Stick it into vial two and draw slowly. The lack of air will keep things tight and uniform. I draw with a 22-23g so most of the time when I remove the needle it lets a little air back in to keep the vacuum from getting too high. You can also vent every few shots to keep it manageable.
This is very easy and you can be extremely accurate by not letting ANY air into the needle/syringe between compounds. I do this a lot, never let me down.
Thank you very much. I will try this method out.Draw from vial one. Do NOT pull the plunger any farther. Air will make this process harder. Stick it into vial two and draw slowly.

I thought about putting air into each vial before drawing any of the compounds to vent the vials and make the drawing process easier. But I will try the method @Fattyone suggested.Nice. You can put some air into the first vial only and in next pin start drawing from the other vial. I agree, if you start messing with air while having the syringe loaded it can go south ez.
