Abstract
Microorganism culture transfer devices are described of the type comprising a manually-grippable handle having a culture contacting tip for contacting a culture and streaking same a plurality of times over a culture plate in order to dilute the culture for purposes of isolating individual colonies. The handle is of a configuration in cross-section defining at least three, preferably four or more, discrete rotational positions when held and rotated by the user's fingers about the longitudinal axis of the handle; and the culture-contacting tip is of a configuration such as to provide a different and distinct surface for contact with the culture in each of the discrete rotational positions of the handle.
