Buddy of mine prepared a small vial of suspended buprenorphine. He ran water and the dissolved tablets thru a .22 filter into a sterile vial, using sterile equipment and taking precautions to maintain sterility. He had the vial a couple days and his bacteriostatic water he needed finally arrived. He transfered the BA water to the sterile vial with a 30g syringe before going to bed. Int he morning, he notices contaminants floating that were not there last time he looked. Little whitish-clear flakes to be exact. He thinks perhaps it came from plastic in the syringe used to transfer the BA, or maybe even the BA bottle itself? He boiled the vial for 30 minutes for a further sterilization precaution, but the flakes remain.
Question is, what the heck could they be?? The plan will be to re-filter, but that was his only sterile vial unfortunately.
