A disc dispenser which for example automatically and simultaneously dispenses a plurality of antibiotic sensitivity discs onto a flat surface such as a layer of agar gel in a petri dish, uses suction applied through tubes 33 to lift each disc. The dispenser comprises a removable magazine unit 11 which carries the required number of standard cartridges, 19, each filled with discs to be dispensed, and these are removed in turn from the cartridges by a rotatable transfer plate (51, Figure 4 not shown), from whence they are transferred to the surface of the gel by means of a plurality of pick-up tubes to which a vacuum is applied via flexible pipes 33. The vacuum causes the discs to become attached to the end 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. <IMAGE>
