Method and device for placing disks, such as antibiotic disks

A device for positioning disks, stored in the stacked state inside a cartridge, said device comprising:

• a zone for receiving a cartridge of disks, inside which zone at least one cartridge of disks can be stored, a piston laterally offset from the zone for receiving a cartridge, means for moving the piston between a high position and a low position in order to allow, in the state in which a disk is positioned on the path followed by the piston, during the transition from the high position to the low position of the piston, the disk to be positioned on any surface positioned in line with the disk by pushing the piston on the disk, a transfer system capable of transferring a disk of the cartridge from the cartridge reception zone to a location, which is disposed on the path that can be followed by said piston during its transition from the high position to the low position and which is called a transit zone, wherein the device comprises a disk movement assist guide that can be positioned in the transit zone and can move in a direction parallel to the up and down direction of movement of the piston, wherein the disk movement assist guide defines an axial through passage for receiving a disk, inside which passage the piston is, during its movement from the high position to the low position, able to slide to an end of travel position, in which it at least partially projects from the axial through passage.
