Peptide reconstitution calculator
Enter the peptide mass in the vial, the volume of diluent added, and the target aliquot quantity. Returns the resulting concentration, the volume that contains that quantity, and how many such aliquots the vial yields. Arithmetic only, for in-vitro reference.
- Volume containing that aliquot
- 0.050 mL
- 50 µL
- Concentration
- 5.00 mg/mL
- 5,000 mcg/mL
- Aliquots per vial
- 40.0

How the math works
Reconstitution concentration is simply the peptide mass divided by the diluent volume: a 10 mg vial reconstituted with 2 mL of bacteriostatic water gives 5 mg/mL, or 5,000 mcg/mL. To locate a 250 mcg aliquot in that solution you divide 250 by 5,000, which is 0.05 mL, or 50 µL.
Adding more diluent lowers the concentration and raises the volume that holds the same quantity, which can make small aliquots easier to measure accurately. The peptide mass itself never changes. Only the volume it is dissolved in does.
