There exists several characteristics that make the difference between a mixture and a compound. A mixture can contain components in any proportions while a compound contains components in fixed proportions.
Best Answer: the longest you should use an open vial of insulin for is 30 days but you will have a 20 day supply per vial if you are using U-100 insulin. 1 cc equals 100 units so a 10 ml bottle contains 1000 units, at 48 units per day that will last you 20 days. not equivalent syringes. use only insulin syringe and read type/ strength of insulin. Too dangerous to discuss on yahoo. not equivalent to TB syringes either.
It depends  on the concentration of insulin in the vial you are using.    One commonly used concentration is 1â¦00 IU/ml, (sometimes called  U100) but this is NOT true for all insulin. If the concentration  is 100 IU/ml, then each ml contains 100 IU and the conversion is  100 units = 1 ml.
