Determination of Cell Density in Bacterial Cultures Using the Hellma Fiber Optic Probe in Combination with the Eppendorf Biospectrometer

Photometric measurement of turbidity for the purpose of determining cell density in a bacterial suspension is a basic method in every molecular biology laboratory. This application note demonstrates the use of a fiber optic probe in combination with the Eppendorf BioSpectrometer, which yields comparable results and thus presents a good alternative to a common measurement method.
