The Good
Very fast and easy to use. Small size fits perfectly on the lab bench.
The Bad
Only measures at a fixed wavelength (600 nm).
The Bottom Line
Consistent measurements using OD600 enabled accurate tracking of bacterial growth phases, which was essential for determining the minimum inhibitory concentration (MIC) of ampicillin in various bacterial mutants, as well as in mutants treated with human-derived antimicrobials. This approach allowed me to discover that certain mutants were sensitive to ampicillin during the early stationary phase, whereas others showed sensitivity to human-derived antimicrobials specifically during the exponential growth phase. Overall, it proved to be a great and reliable method for tracking cell growth in liquid cultures on a daily basis.
