Title
(EN) CENTRIFUGAL FILTER AND METHOD FOR CAPTURING AND OBSERVING FINE PARTICLE IN LIQUID BY USING SAME
(FR) FILTRE CENTRIFUGE ET PROCÉDÉ DE CAPTURE ET D'OBSERVATION DE PARTICULES FINES DANS UN LIQUIDE À L'AIDE DE CELUI-CI

Abstract
(EN) The purpose of the present invention is to suppress an influence on detection accuracy of fine particles included in liquid in a centrifugal filtration device. Provided is a centrifugal filtration device comprising: a filtration membrane 26 that filters liquid; a cartridge 25 that supports the filtration membrane 26 and forms, together with the filtration membrane 26, a liquid chamber 27, in which the liquid is retained; a rotation member 14 that rotates around the rotation center C and supports the cartridge 25 so that the filtration membrane 26 is positioned on the outer side of the liquid chamber 27 with respect to the rotation center C, wherein the rotation member 14 has a flow channel communicating with the liquid chamber 27 and at least a part of a liquid contact part thereof contacting with the liquid in the flow channel is formed of titanium or a titanium alloy.
(FR) L'objectif de la présente invention est de supprimer une influence sur la précision de détection de particules fines incluses dans un liquide dans un dispositif de filtration centrifuge. Dans ce but, l'invention concerne un dispositif de filtration centrifuge comprenant : une membrane de filtration (26) qui filtre un liquide ; une cartouche (25) qui supporte la membrane de filtration (26) et forme, conjointement avec la membrane de filtration (26), une chambre de liquide (27) dans laquelle le liquide est retenu ; un élément de rotation (14) qui tourne autour du centre de rotation (C) et supporte la cartouche (25) de sorte que la membrane de filtration (26) soit positionnée sur le côté externe de la chambre de liquide (27) par rapport au centre de rotation (C), l'élément de rotation (14) ayant un canal d'écoulement communiquant avec la chambre de liquide (27) et au moins une partie d'une partie de contact de liquide de celle-ci en contact avec le liquide dans le canal d'écoulement étant formée de titane ou d'un alliage de titane.
