Title
(EN) A DEVICE AND METHOD FOR REMOVING PARTICULATE MATERIAL FROM SUSPENSIONS
(FR) DISPOSITIF ET METHODE PERMETTANT DE RETIRER UNE SUBSTANCE PARTICULAIRE EN SUSPENSION
Abstract
(EN)
A filtering device comprising a filtering element that can be attached to an adapter. The filtering element comprises a mesh surrounding a cavity. The mesh of the filtering element is constructed to have sufficient porosity so that hydrostatic and mechanical pressures force the liquid components of a suspension into the cavity of the filtering element from where they can be aspirated and collected. Preferably, at least one semi-rigid rib supports the mesh. This invention also involves a method for using the filtering device in a variety of applications. These applications include, but are not limited to, sampling of suspensions, filtration of particulate materials from suspensions, and purification or isolation of chemical or biological components contained within the a suspension.

Cette invention concerne un dispositif de filtrage comprenant un élément filtrant pouvant être monté sur un adaptateur. L'élément filtrant comprend un treillis entourant une cavité. Le treillis de l'élément filtrant présente une porosité suffisante pour que les pressions hydrostatiques et mécaniques forcent les composantes liquides de la suspension dans la cavité de l'élément filtrant, d'où elles peuvent être aspirées et recueillies. Le treillis est maintenu de préférence par une nervure semi-rigide. L'invention concerne égalent une méthodes d'utilisation du dispositif filtrant dans diverses applications concernant entre autres, mais pas uniquement, l'échantillonnage de suspensions, la filtration de matériaux particulaires présents dans des suspension et la purification ou l'isolement de composants chimiques ou biologiques en suspension.
