Abstract
First and second containers (R1; R2) are successively brought to a transvasation or decanting station (C) in which the samples are metered. For this purpose, a piston (17) is mounted so as to be able to penetrate each first container (R1), which can be lifted, when it enters the decanting station (C). The quantity of sample in the first container (R1) is greater than the quantity to be precisely metered which is poured into the second container (R2) by means of a pouring assembly (24 to 36) situated above it. A pouring member (40) may be placed between the second container and the pouring assembly. Thus, when the first container acts as cylinder on the piston (17), a first quantity of the sample rinses the transvasation or decanting circuit to eliminate any residue of a preceding sample, while the pouring member is located between the pouring assembly (24 to 36) and the second container, then an exactly metered quantity of the sample is poured into the second container after withdrawal of the pouring member ( 40).
