Abstract
A dispenser for antibiotic sensitivity discs which automatically and simultaneously dispenses a plurality of discs onto a flat surface, for example a layer of agar gel in a petri dish. The dispenser comprises a removable magazine unit which carries the required number of standard cartridges, each filled with discs to be dispensed. The discs are in turn removed mechanically from the cartridges from where they are transferred to the surface of the gel by a plurality of pick-up tubes to which a vacuum is applied. The vacuum causes the discs to become attached to the ends of respective tubes so that the discs move with the tubes onto the gel surface, and are pressed onto the gel surface by a pressure equal to the weight of the tubes.
