title: A simple device for uniform inoculation of nutrient surfaces.
abstract: A simple and inexpensive device for uniform surface inoculation is described. Efficiency and uniformity of inoculation were estimated with agar plates exposed to a bacterial suspension, containing 10 different strains, atomized with a spray gun. The fine mist settled, after a fall of 106 cm, upon the agar surfaces at the bottom of a cylindrical chamber. No significant differences were observed with regard to uniformity of inoculation between nine plates.
