    • The device is intended to portion a liquid sample into several portions of determined volume. It comprises members that are relatively displaceable from a first relative position to a second relative position. One of these members comprises a series of portion-receiving channels defining the above-mentioned volumes. The other member comprises a first series of channels which put the portion-receiving channels in communication with one another and with the exterior so that they can be filled with the liquid, in the first relative position, and a second series of channels communicating with the portion-receiving channels for collecting the portions retained in these latter channels, in the second relative position.
    • 该装置旨在将液体样品分成几个确定体积的部分。 它包括可从第一相对位置相对移位到第二相对位置的构件。 这些构件中的一个包括限定上述体积的一系列部分接收通道。 另一个构件包括第一系列通道,其将部分接收通道彼此连通并且与外部连通,使得它们可以在第一相对位置中被填充液体,并且第二系列通道与第二系列通道 部分接收通道,用于收集在第二相对位置中保留在这些后一通道中的部分。
