title: A high-precision and large-capacity laser biophotometer.
abstract: A new type of biophotometer is described. Very precise and reproducible measurements of bacterial concentration can be performed at 3-s intervals for each of 32 simultaneously developing bacterial cultures. The large number of results is handled with modern data acquisition and computer-processing techniques.
