The device for spraying a reagent onto a support () adapted to retain microorganisms on a predetermined surface (), comprises a spraying bell () as well as a nozzle () for emitting a jet of droplets of said reagent into a spraying chamber () comprised by said bell (), said device also comprising an absorbent pad () mounted against said bell () transversely to said jet and closing said chamber () from the opposite side to said nozzle () with the exception of a circular central opening () provided in said pad (), the diameter of said central opening () being adapted to enable a portion of said jet, when said device faces said support () and is at a predetermined distance therefrom, to pass through said central opening () over its entire area and be deposited on the whole of said predetermined surface () of said support ().

Device for spraying a reagent for fast microbiological analysis

Device for spraying a reagent onto a support adapted to retain microorganisms on a predetermined surface. The device includes a spraying bell as well as a nozzle for emitting a jet of droplets of the reagent into a spraying chamber comprised by the bell, the device also including an absorbent pad mounted against the bell transversely to the jet and closing the chamber from the opposite side to the nozzle with the exception of a circular central opening provided in the pad, the diameter of the central opening being adapted to enable a portion of the jet, when the device faces the support and is at a predetermined distance therefrom, to pass through the central opening over its entire area and be deposited on the whole of the predetermined surface of the support.

The peristaltic pump () comprises a rotor with rollers, a mobile jaw having an open position and a closed position, and further comprises, on each side of the rotor, a locating member for said tube adapted to receive it when it is pressed in and to allow it to slide in the longitudinal direction in which the locating member extends, said locating members being disposed in a line between the rotor and the mobile jaw in the open position.

The method includes the step of positioning the device on a sheath () having, for each latching tab (), a portion adapted to be housed between this tab and a cylindrical wall of the device; the step of making the sheath enter between each tab and the cylindrical wall until means preventing the withdrawal of the tabs are released; and the step of moving the two bodies () away from each other. The instrument has, in addition to the sheath (), a guidance slide ().
