Enter the mass of the lyophilised compound and the volume of solvent (for example bacteriostatic water) you're adding, and this tool works out the concentration of the resulting research solution. It is a concentration calculator for laboratory preparation — it does not provide dosing or usage guidance of any kind.
concentration (mg/ml) = compound mass (mg) ÷ solvent volume (ml)Important: This tool calculates the concentration of a reconstituted solution for laboratory research preparation. It is not dosing, administration or usage guidance, and nothing here should be read as a recommendation to use any compound in a human or animal. Our products are supplied strictly for laboratory research use only.
Reconstitution concentration is simple arithmetic: the mass of compound divided by the volume of solvent added. Adding more solvent gives a more dilute solution; adding less gives a more concentrated one. The mass is fixed by the vial — only the solvent volume changes the concentration. The physical technique for adding solvent is covered in our guide to reconstituting a research peptide.
Divide the mass of peptide by the volume of solvent added: concentration (mg/ml) = compound mass (mg) ÷ solvent volume (ml). For example, 10 mg dissolved in 2 ml gives 5 mg/ml. This describes the strength of the prepared research solution only.
Bacteriostatic water is the standard laboratory solvent for reconstituting most lyophilised research peptides. The volume added sets the concentration of the resulting solution.
