Abstract: Device (145) for dispensing drops of liquid, characterised in that it comprises: —at least one container (100) for a liquid, comprising at least one internal chamber and an upper opening, each chamber having a lower aperture and a seal sealing the upper opening, the seal having a substantially planar resiliently deformabie flexible portion, —at least one mechanical actuation means (146) configured to deform a flexible portion of a seal of at least one container, —a means (147) for selecting the volume of a drop to be dispensed from a plurality of drop volumes, a means (148) for determining the volume of liquid present in at least one container, and—a means (149) for controlling the actuation means, which means controls the movement from at least one point of the flexible portion of a container seal, as a non-constant function of the drop volume to be dispensed and the volume of liquid present in the container.

Abstract: The distribution carousel (1) comprising a body (10) comprises a set of receptacles (13) of a set of reservoirs (20, 21) for fluid containing a fluid that is to be distributed, each one of the reservoirs comprising a distribution orifice (22) having a distribution axis (X), the set of receptacles being arranged in the body such that, once the reservoirs of the set of reservoirs are in place in the associated receptacles, the distribution axes of the reservoirs of the set of reservoirs intersect in a service region (Z) around a single mixing point (P).
