Worked example
Diluting 1 M stock to 100 mM with a 50 mL final volume requires 5 mL stock and 45 mL diluent—a 10× dilution.
C1V1 dilution

How to use
- Enter C1, C2, and V2 with their units.
- Calculate V1 and diluent.
- Review the bench-ready instruction and copy the complete summary.
Validation and limitations
All inputs must be positive, and C2 cannot exceed C1. The tool will not present a concentration-up operation as a dilution recipe. Account for volume non-additivity when your chemistry requires it.
