Abstract

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.
