Research Tool
Enter vial mass and diluent volume to calculate stock-solution concentration in mg/mL.
Semaglutide is supplied lyophilized at milligram vial masses, so working concentrations are expressed in mg/mL and the volumes involved are small.

Concentration (mg/mL) = peptide mass (mg) ÷ diluent volume (mL). For in-vitro laboratory research use only.

A 10 mg vial in 2 mL gives 5 mg/mL; a 30 mg vial in the same 2 mL gives 15 mg/mL. Halving the volume doubles the concentration — the mass in the vial does not change, only how it is distributed.
Default values are arithmetic examples, not preparation recommendations. For in-vitro lab work.
Each value is the vial mass divided by the diluent volume, in mg/mL. These are arithmetic examples, not preparation recommendations.
| Vial | 1 mL | 2 mL | 3 mL | 5 mL |
|---|---|---|---|---|
| 2 mg | 2 | 1 | 0.67 | 0.4 |
| 5 mg | 5 | 2.5 | 1.67 | 1 |
| 10 mg | 10 | 5 | 3.33 | 2 |
| 30 mg | 30 | 15 | 10 | 6 |
