I went down to TJ the other day and bought 16 sust 250's and moved the liquid into 2 small bottles so i could bring them back home. Now that i exposed them to air, should they be refrigerated?
every time you inject from a multidose vial you subject it to air. its not so much airborne contaminents as it is surface contaminants. I would sterile filter it into a sterile vial if it were me.
