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.
U-100 will have 100 units per mL, and U-40 has 40 units per mL. This means that U-100 has 2.5 times the amount of active insulin per mL, therefore 2.5 times as strong. Appropriate syringes are made for use with the respective insulin, marked with the correct measure for dosage. We strongly recommend that you use matching insulin and syringes. However, it is possible to use the below conversion chart to convert from U-40 to U-100 or U-100 to U-40 effortlessly.
