- Cell Doubling Time Calculator
- Calculate population doubling time, specific growth rate and number of population doublings from two cell counts taken a known time apart in culture.
- Bacterial Generation Time Calculator
- Calculate the number of generations, generation time and mean growth rate constant k from two bacterial counts taken across a log-phase incubation.
