Abstract: The disclosure relates to a device for dispensing a prescribed material into a Petri dish, each Petri dish including a removable lid capable of being arranged on a bottom that is not as broad as the latter, bringing the Petri dish to a material-dispensing station. According to the disclosure, the device includes a piston comprising a plate for supporting the bottom at the material-dispensing station and a device for rotating the plate on itself relative to the dispensing head, arranged so as to rotate the bottom relative to dispensing head in the position for dispensing the material into the bottom, in which the material outlet tip is arranged relative to plate in order to dispense the material into the rotated bottom.

Abstract: The disclosure relates to a device for dispensing a prescribed product in a Petri dish, the device comprising pistons, a transfer member with lid-bearing openings and a dish bottom, and a dispensor. According to the disclosure, the transfer member is a shuttle capable of translation relative to the base according to a direct reciprocating movement of the bearing openings between either of first and second stop positions, the dispensor being arranged so as to dispense the product above the inner opening and under the upper opening at the bottom of the dish when the openings are in a position selected from the first and second stop positions.
