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.
A U is a unit. The numbers 40 or 100 refer to how much insulin (the number of units) is in a set volume of fluid â which in this case is one milliliter. For example, U-100 has 100 units per milliliter and U-40 has 40 units per milliliter.It is possible to use a 1 ml (commonly referred to as a TB syringe) for insulin.So...U-100 insulin is more concentrated. There is essentially 2 Â½ times more insulin in a milliliter as compared to U-40.or example, U-100 has 100 units per milliliter and U-40 has 40 units per milliliter.
