What serial dilution means
A serial dilution is a stepwise dilution where each step uses a repeated factor. The record should make the starting concentration, factor, and step count clear.
Research documentation example
A starting concentration of 100 mg/mL with a 10× step factor produces 10 mg/mL after one step, 1 mg/mL after two steps, and 0.1 mg/mL after three steps.
Common documentation mistakes
- Not labeling the step number.
- Changing units mid-table.
- Recording the factor but not the calculated concentration.
