Research Calculators

Free calculators for preparing and characterizing research solutions — molarity, dilution, concentration, and reconstitution. Measurement math only, for laboratory use.

Molarity calculator

Mass + molecular weight + volume → molar concentration. For preparing research stock solutions.

Mass (mg) Molecular weight (g/mol) Volume (mL)

—

Dilution calculator (C₁V₁ = C₂V₂)

Solve for any one value — leave the unknown blank.

Stock conc. C₁ Stock vol. V₁ (mL) Final conc. C₂ Final vol. V₂ (mL)

—

Concentration calculator

Total mass + solvent volume → concentration (mg/mL) and the volume holding a target mass.

Total mass (mg) Solvent volume (mL) Target mass (mg)

For laboratory and research use only. These tools perform measurement and dilution math for preparing research solutions — they are not medical, dosing, or administration guidance.
