Calculators

• Reconstitution calculator

  Concentration from vial mass and diluent volume, in mg/mL and µg/mL, with the reverse calculation for a target concentration and the volume containing a given mass.

• Serial dilution calculator

  Free C1V1 = C2V2 dilution calculator. Work out how much stock solution and how much diluent to combine for any target concentration and final volume.

• Peptide content calculator

  Convert label mass to actual peptide mass using the peptide content figure from a certificate of analysis, and see the true concentration after reconstitution.

• Peptide molar conversion

  Convert peptide mass to moles and concentration to molarity using molecular weight. Micromoles, nanomoles, millimolar and micromolar from milligrams and mg/mL.

• Volume and unit converter

  Convert between mass, volume and syringe units at a given concentration. Micrograms to millilitres to insulin-syringe units, with fill percentage.
