Lab calculator.
Concentration and aliquot arithmetic for laboratory planning. No dosing or administration recommendations.
Concentration
Volume per aliquot
Mass ÷ final volume = concentration.
Aliquot mass ÷ concentration = aliquot volume.
Before accepting a result
Check four common concentration-calculator errors: units, mass versus concentration, final volume and blend inputs.
How the calculator works
Mass concentration equals material mass divided by final solution volume. Aliquot volume equals the target mass divided by that concentration.
| Calculation | Example |
|---|---|
| Concentration | 10 mg ÷ 2 mL = 5 mg/mL |
| Aliquot volume | 0.5 mg ÷ 5 mg/mL = 0.1 mL |
| Mass conversion | 1 mg = 1,000 micrograms |
Use final solution volume. For blends, total mass does not establish each component’s concentration. The calculator cannot verify identity, dissolution, stability or suitability.
