Vial strength and diluent volume in, concentration and insulin-syringe units out. The same arithmetic our concentration guide works through by hand.
Converts vial strength and diluent volume into insulin-syringe units.
The reconstituted vial holds 200 units in total on a 100-unit-per-mL scale.
2 mL is more than the 0.5 mL syringe holds, so a single draw cannot take the full volume.
Arithmetic only, for laboratory measurement. It does not recommend a quantity, and nothing here is a protocol. Research use only.
Concentration is the vial contents divided by the volume of bacteriostatic water added: a 10 mg vial reconstituted with 2 mL is 5 mg/mL.
An insulin syringe is graduated so that 100 units correspond to 1 mL, regardless of whether the barrel holds 0.3, 0.5 or 1 mL. So mcg per unit is simply the mcg/mL figure divided by 100 — the syringe capacity changes how much you can draw at once, not what a unit means.
Choosing a larger diluent volume does not change how much peptide is in the vial. It changes how many graduations that peptide is spread across, which is the whole reason the volume is worth thinking about before you add it.
This tool performs unit conversion only. It does not recommend a quantity and is not a protocol. All products are supplied for in-vitro laboratory research use only.
