Evidently a 20guage was too big for this particular vial and air bubbles flooded the vial as I was drawing. The second day I used a 25 gauge to draw but the pressure from the original site with the 20 gauge forced more outside air into the vial. Is it still sterile and safe to use? I know you even want to limit time for the needle to exposed to the air so I’m assuming pulling air into the vial daily can’t be good right?
