PROBLEM TO BE SOLVED: To provide a device of the same type that both has better performance and is more practical while remaining reliable in terms of the risks of contaminations of the support to analyze. SOLUTION: The device for spraying a reagent onto a support 81 adapted to retain microorganisms on a predetermined surface 82, comprises a spraying bell 3 as well as a nozzle 71 for emitting a jet of droplets of the reagent into a spraying chamber 34 comprised by the bell 3, the device also comprising an absorbent pad 5 mounted against the bell 3 transversely to the jet and closing the chamber 34 from the opposite side to the nozzle 71 with the exception of a circular central opening 51 provided in the pad 5, the diameter of the central opening 51 being adapted to enable a portion of the jet, when the device faces the support 81 and is at a predetermined distance therefrom, to pass through the central opening 51 over its entire area and be deposited on the whole of the predetermined surface 82 of the support 81.
