Reconstitution Calculator

Converts vial amount and diluent volume into concentration, U-100 syringe units, and reference draw volumes.

Lyophilised amount

Diluent volume

Reference amount Used for the draw-volume and doses-per-vial estimate. mcg

Syringe capacity

Assumptions

1 mg = 1,000 mcg.

U-100 syringe: 100 units = 1 mL.

1 syringe unit = 0.01 mL.

Concentration = total mcg / mL added.

Reference draw

10 units

0.100 mL for 250 mcg

Within selected syringe
