title: A comparative study of McFarland turbidity standards and the Densimat photometer to determine bacterial cell density.
abstract: McFarland Turbidity Standards and the Densimat photometer were compared for their accuracy to adjust bacterial suspensions. Six bacterial species were tested with both methods. Statistical analyses showed that adjusting bacterial suspensions with the Densimat photometer results in less variation within assays and in a more accurate determination of bacterial inocula.
