Title
(EN) DEVICE FOR CONTROLLED LAYERING OF LIQUIDS
(FR) DISPOSITIF POUR LA STRATIFICATION COMMANDÉE DE LIQUIDES
Abstract
(EN) A device for controlled layering of liquids, in particular for layering liquids prior separation with density gradient centrifugation, the device comprising a loading chamber (11), a draining chamber (40) and a liquid flow regulating element from the loading chamber (11) to the draining chamber (40), characterised in that the liquid flow regulating element comprises a piston type mechanism (19) and at least one flow transfer channel (32) in the wall of the flow segment (31), wherein the piston type mechanism (19) comprising a flow segment (31) and the piston (20) axially movable with respect to the flow segment (31), the piston (20) is provided with a shaft (23) and a sealing lip (22) tightly adhering to the inner surface of the flow segment (31) wall. The invention also relates to a density gradient centrifugation assembly comprising a controlled layering device and the centrifuge container (61).
(FR) L'invention porte sur un dispositif pour la stratification commandée de liquides, en particulier pour la stratification de liquides avant la séparation avec une centrifugation à gradient de densité, le dispositif comprenant une chambre de chargement (11), une chambre de drainage (40) et un élément de régulation d'écoulement de liquide à partir de la chambre de chargement (11) à la chambre de drainage (40), caractérisé en ce que l'élément de régulation de débit de liquide comprend un mécanisme de type piston (19) et au moins un canal de transfert d'écoulement (32) dans la paroi du segment d'écoulement (31), le mécanisme de type piston (19) comprenant un segment d'écoulement (31) et le piston (20) mobile axialement par rapport au segment d'écoulement (31), le piston (20) étant pourvu d'un arbre (23) et d'une lèvre d'étanchéité (22) adhérant étroitement à la surface interne de la paroi de segment d'écoulement (31). L'invention concerne également un ensemble de centrifugation à gradient de densité comprenant un dispositif de stratification commandé et le récipient centrifuge (61).
