Dilution Calculator (C1V1 = C2V2)
Calculate the final volume needed to achieve a target concentration using the dilution equation C1V1 = C2V2.
How to Use the Dilution Calculator
- Enter the initial (stock) concentration (C1).
- Enter the initial (stock) volume you will use (V1).
- Enter the desired final concentration (C2).
- Click Calculate to find the required final volume and diluent volume.
使用例
- •Preparing working solutions from concentrated stocks in the lab.
- •Calculating dilutions for cell culture media preparation.
- •Drug dilution calculations for pharmacy and clinical settings.
計算式
Formula: C1 × V1 = C2 × V2 → V2 = (C1 × V1) / C2. Diluent volume = V2 − V1.
よくある質問
What is the C1V1 = C2V2 equation?
This fundamental chemistry equation states that the product of initial concentration and initial volume equals the product of final concentration and final volume. It applies to any serial or direct dilution.
What units should I use?
Concentration units (C1 and C2) must be the same (e.g., both in mg/mL or both in mM). Volume units (V1) can be mL, µL, or L — the result will be in the same unit.
