Abstract
A number of discs are simultaneously dispensed into a culture dish from a dispenser having an array of self-contained dispensers locked in apertured sockets on a base frame. The individual dispensers are simultaneously operated by an actuating plate which engages actuating pins on each of them. The height of the dispenser above the culture dish is adjustable by cam and follower engagement of the base plate within a height-adjusting ring. Indicia and yieldable detents are provided for indexing the height of the base plate. The individual dispensers each include a chute-incorporating body, cover, slide plate, spring and tubular cartridge. The open tops of the chutes provide visual confirmation that a disc has been discharged from each of the dispensers. Weights and spring clips in the cartridges push the discs successively into firm contact with the dispensing slide plates for dependably delivering them into the dispenser chutes.
