Peptide Reconstitution Calculator
A simple concentration aid for preparing laboratory research samples. Enter the mass of the research compound in your vial and the volume of solvent you added, and this tool returns the resulting solution concentration — in mg/mL and mcg/mL — plus the amount of compound contained in any sample volume you choose. It performs concentration arithmetic only.

What is reconstitution?
In the laboratory, reconstitution means dissolving a lyophilised (freeze-dried) research compound in a solvent to create a liquid research sample at a known, measurable concentration. Recording the mass of compound and the exact volume of solvent added lets you characterise the concentration of the sample for in-vitro research work.
BAC water and other solvents
Bacteriostatic water (often called BAC water) and sterile water are common solvents used to reconstitute lyophilised research compounds in a laboratory setting. The solvent does not change the mass of compound present — it sets the volume the compound is dissolved in, and therefore the concentration of the prepared research sample.
The concentration maths
Concentration is mass divided by volume: concentration (mg/mL) = compound mass (mg) ÷ solvent volume (mL). Multiply by 1,000 to express the same concentration in mcg/mL. To find how much compound is contained in a given sample volume, multiply the concentration by that volume. These are purely arithmetic relationships for characterising research samples.
