The core formula
Concentration is simply vial content divided by diluent volume. A 10mg vial reconstituted with 2mL of bacteriostatic water gives 5mg per mL, which is 5000mcg per mL.
On a standard 100-unit insulin syringe, one millilitre equals 100 units, so that same preparation is 50mcg per unit. Our on-site reconstitution calculator performs this conversion for you.
Mistake one: confusing units with millilitres
Syringe graduations are units, not millilitres. Ten units on a 100-unit syringe is 0.1mL. Treating the two as interchangeable produces a tenfold error in every downstream figure.
Mistake two: assuming displaced volume
At milligram quantities the solid displaces a negligible volume, so 2mL of diluent gives a 2mL solution. At higher masses, and for blends totalling 80mg or more, the assumption starts to drift and volumetric verification is worthwhile.
