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.
Dosage units are determined by the type of insulin pen you are using for insulin injection. Half units refer to needles that use half units (ex: 1, 1.5, 2, 2.5, 3, 3.5, etc). Whole units refer to needles that use whole units only (1, 2, 3, 4, 5, 6, etc).
