Serial Dilution Calculator

Find the final concentration after several dilution steps.

Final concentration 1

Total dilution (x) 1,000

Formula: final = initial ÷ factor^steps

Step-by-step with your numbers:

1. Values used:

2. Initial concentration = 1,000

3. Dilution factor per step = 10

4. Number of steps = 3

6. Final concentration = 1

7. Total dilution = 1,000x

Did we solve your problem today?

Serial dilutions repeatedly dilute a sample by the same factor each step.

The math behind it

final = initial ÷ (dilution factor)^number of steps.

1000 at 1:10 × 3 steps → 1.
