|---|---|
| factor | For a 1:10 dilution, enter 10. |
When to use this calculator
The calculator reports the nominal concentration sequence. Actual accuracy still depends on pipetting and mixing.
Worked example
The page opens with these example values. The result below is pre-generated for reference.
- Cₙ = C₀/factorⁿ = 1/10^5 = 0.00001 arbitrary units
0.00001 arbitrary units
Common mistakes
- A 1:10 dilution means one tenth of the previous concentration, not subtracting 10%.
