10-fold Serial Dilution Example for a Standard Curve

Worked example showing how to build a standard curve dilution series without carryover mistakes.

Scenario

You have a concentrated stock and need six 10-fold dilution steps for a standard curve.

The example focuses on maintaining consistent transfer volumes and enough final material for replicates.

Inputs to confirm

Define the target dilution factor and the transfer volume used at every step.

Make sure each tube has enough final volume for replicates and repeat testing.

Label the tubes in order before starting the transfer sequence.

Why this is valuable

Researchers often know the dilution factor conceptually but still make avoidable bench errors when planning total volume.

This page turns a generic dilution calculator into a repeatable standard-curve setup reference.

Common failure points

Reusing tips and accidentally contaminating lower concentration tubes.

Mixing too weakly after transfer.

Running out of final volume because replicate planning was not included at the start.
