Research Tool
Enter vial amount and diluent volume to calculate stock-solution concentration in IU/mL.
This page works in IU because the vial is labelled in IU; no mass conversion is made. A 5,000 IU vial in 5 mL gives 1,000 IU/mL.

IU/mL
Concentration (IU/mL) = vial amount (IU) ÷ diluent volume (mL). For in-vitro laboratory research use only.
Record the compound, mass, diluent volume, concentration, date prepared and optional lot.

A 10,000 IU vial in the same 5 mL gives 2,000 IU/mL. Concentration is the labelled IU amount divided by the diluent volume.
Default values are arithmetic examples, not preparation recommendations. For in-vitro lab work.
