This paper describes how a filterbased microplate photometer, Thermo Scientific Multiskan FC, can be used reliably and easily to measure turbidity of bacterial samples in antibiotic susceptibility studies. The growth curve measurements were performed on a 96-well microplate. The performance of turbidometric measurements on a 96-well microplate and the liquid evaporation from 96- and 384-well microplates during long incubation were also studied.
