Reconstitution calculator

For preparing a stock solution of known concentration in a laboratory setting. Enter the mass of lyophilized peptide in the vial and the volume of solvent used to reconstitute it; the result is the resulting stock concentration in mg/mL.

Stock concentration: 2.50 mg/mL
Stock concentration (µg/µL): 2.50 µg/µL

1 mg/mL is numerically equivalent to 1 µg/µL — a common in-vitro dilution reference.
