Scientific Documentation

A serial dilution is a stepwise dilution of a substance in solution. It is commonly used to lower concentrations to a useful range for experimentation or to isolate single microbial colonies.

The Calculation: $C_n = C_0 / (DF^n)$, where $C_n$ is the final concentration, $C_0$ is the starting concentration, $DF$ is the dilution factor, and $n$ is the number of steps.

Laboratory Significance: Mastering serial dilutions is fundamental for determining the titer of viral stocks, quantifying bacterial cell counts, and creating standard curves for assays like ELISA or Western Blotting. Accuracy here prevents propagation of errors throughout your entire downstream protocol.
