Laboratory Handling
Laboratory stock-solution calculator
Enter vial mass (mg) and diluent volume (mL) to obtain concentration (mg/mL) for in-vitro handling. This tool does not calculate a dose, a syringe unit, or an administration volume. For laboratory research use only. Not for human or veterinary use.
Stock solution inputs
mg
mL
The calculation
mg ÷ mL = mg/mL
Divide the mass of lyophilized material stated on the vial by the volume of diluent added to it. The result is the concentration of the reconstituted stock solution. Concentration is a property of the solution, not an amount to administer.
Disclaimer: This calculator is for in-vitro laboratory handling only. It does not calculate a dose, a syringe unit, or an administration volume, and no output of it should be interpreted as one. Verify all calculations independently against the mass stated on the Certificate of Analysis for the material in hand. Not for human or veterinary use.
