Research Solution Concentration Calculator

This calculator turns two numbers you already have — the milligrams in a research vial and the millilitres of laboratory solvent added — into the concentration of the resulting solution in mg/mL. It is a laboratory preparation and record-keeping aid for researchers; it computes solutions, never anything about a subject.

Laboratory preparation tool

Enter what's in the vial and how much laboratory solvent you're adding, and get the exact concentration of the resulting research solution for your lab records.

One thing to understand before you calculate: this tool — and everything we sell — is for education and laboratory research. Researchers and labs use it to prepare and document research solutions. It isn't medical advice or dosing guidance, and nothing here is for human or veterinary consumption. Full details in our Terms of Service.

Everything this calculator returns describes a solution on a lab bench: milligrams of material, milliliters of solvent, the concentration that results. That's by design — it's an educational tool for researchers, and it offers no guidance about administering anything to anyone. What you do in your lab is governed by your institution's protocols and applicable law.

Looking for a reconstitution calculator?

We don't provide one — these are research-use-only compounds. Use our Research Solution Concentration Calculator for laboratory solution math instead: vial contents and solvent volume in, solution concentration out.
