Laboratory tool
Concentration calculator.
A unit conversion tool for laboratory work. Calculated concentration does not verify a vial’s measured content or establish suitability for an experiment.
Research tool
Reconstitution calculator
Your vial. Your volume. Clear results.
Enter two values to calculate the concentration of your solution.
Total peptide amount shown on the vial, in milligrams (mg).
Volume of diluent added, in millilitres (mL). Use your measured final volume if it differs.
Try it: 10 mg + 2 mL
Your concentration
Start with your vial details
Enter a positive vial amount and diluent volume. Your result updates automatically.
Know your units: 1 mg = 1,000 mcg. On a U-100 scale, 100 units = 1 mL. These markings measure volume, not peptide mass.
Assumes complete dissolution. For blends, enter total peptide mass; results describe the combined concentration. Research reference only; not dosing or administration guidance.
Before calculating
Use the mass and solvent volume specified in your validated protocol. Label mass and measured content are different: see the applicable report where available. We do not provide dosing or administration guidance.
