PEPTIDE RECONSTITUTION CALCULATOR.
A dilution calculator for laboratory documentation. Enter the lyophilised quantity in the vial, the volume of diluent added and the target quantity per withdrawal to obtain the resulting concentration and the corresponding syringe graduation.

The underlying arithmetic
- Concentration = quantity in vial ÷ diluent volume.
- Volume per withdrawal = target quantity ÷ concentration.
- Graduation marks = volume per withdrawal × graduations per millilitre.

Scientific notes
Reconstitution is a dilution calculation: the mass in the vial does not change, only the volume it is dissolved in.
Lyophilised material may add a small volume of its own, so the final volume can differ slightly from the diluent volume entered.
Concentration, stability and solubility depend on the individual compound; peptides are not interchangeable in these respects.
This calculator performs arithmetic only. It does not evaluate suitability, safety or biological effect, and it is not guidance for use in humans or animals.
