Abstract

Um bei einer Filtriervorrichtung zum Abtrennen und Sammeln von Zellen und Partikeln aus Flüssigkeiten den labortechnischen Aufwand zu senken und durch deren Verwendung, insbesondere bei quantitativen Methoden der Auswertung, die Effizienz zu erhöhen, diese Methoden zu standardisieren und wirtschaftlicher zu gestalten, wird eine pipettenartige Filtriervorrichtung (1) vorgeschlagen, bei welcher ein Pipettenrohr (2) einerends flüssigkeitsdicht an einen im Querschnitt erweiterten, beidseits geöffneten Pipettenkörper (3) angesetzt ist, in welchem wenigstens ein Filtersegment (4) angeordnet ist, das umlaufend flüssigkeitsdicht an der Innenwand (5) des Pipettenkörpers (3) anliegt.
