CA 2401819

The invention provides apparatus and methods for dividing a sample, into a plurality of subsamples without the need for pipetting or for other manual operations. Sample is placed, via inlet (2) into sample reservoir (4) in fluid communication with a main charging channel (1) which, in turn, is in fluid communication with a plurality of fractionation channels (5), with valves and vents and terminal purge channel (9). Prior to its use, the plate described above is mated with a receptacle plate, for receiving subsample via fractionation channel valves (6), and to a lid which seals the channels against leakage. The sealed device is subjected to centrifugation in order to distribute sample.

L'invention concerne un dispositif et des procédés permettant de diviser un échantillon, notamment un échantillon liquide, en une pluralité de sous-échantillons sans pipetage ni autre opération manuelle. L'invention est particulièrement utile pour isoler des entités dont la présence est soupçonnée dans un échantillon, en vue d'une analyse individuelle.
