The invention includes a filtration apparatus for processing a plurality of fluid samples into sample wells is provided. In one embodiment, the filtration apparatus includes a purification tray and a sample well tray with a plurality of sample wells. The purification tray includes a filter plate having a plurality of columns with discharge openings at the bottom thereof, at least one filter positioned in the columns of the filter plate for filtering the fluid samples as they pass therethrough, a heat plate positioned adjacent the columns of the filter plate, and a vent plate positioned below the heat plate. The heat plate is configured for transferring heat to the columns of the filter plate. The vent plate includes vents for permitting aerosols from the sample wells of the sample well tray to escape. A sample well tray with a plurality of the sample wells is positioned so that the sample wells align with the discharge openings of the filter plate columns to receive the liquid sample therein.

L'invention concerne un dispositif de filtration permettant de traiter une pluralité d'échantillons de fluide qui sont introduits dans des cupules. Dans une forme de réalisation particulière, ce dispositif de filtration comprend un plateau de purification et un plateau à cupules contenant une pluralité de cupules destinées aux échantillons. Le plateau de purification comprend une plaque de filtration possédant une pluralité de colonnes au fond desquelles se trouvent des orifices d'évacuation, et au moins un filtre placé dans les colonnes de la plaque filtrante à travers lequel on fait passer les échantillons pour les filtrer, une plaque chauffante adjacente aux colonnes de la plaque de filtration et une plaque de ventilation placée sous cette plaque chauffante. La plaque chauffante est conçue de manière à transférer de la chaleur dans les colonnes de la plaque de filtration. La plaque de ventilation comprend des évents permettant l'évacuation des aérosols en provenance des cupules d'échantillons du plateau à cupules. On dispose un plateau à cupules comprenant une pluralité de cupules d'échantillons de manière à placer les cupules dans l'alignement des orifices d'évacuation des colonnes de la plaque de filtration, afin de recueillir les échantillons de liquide dans les cupules.
