WebThe apparatus described is a device allowing rapid measurement of susceptibility zone diameters obtained by the Kirby-Bauer method. The device consists of a series of radially arranged strips upon the lid of a microbiologic plate. The strips are transparent, labeled with the antibiotic tested, and slightly movable circumferentially.
