MIKROPIPETTIERGERÄTMICROPIPETTING DEVICE
-'^ (Die Erfindung betrifft eine Vorrichtung zum gleichzeitigen Pipettieren von einer Mehrzahl gleich großer Elüssigkeitsmengen in der Größenordnung eines Mikrouters.- '^ ( The invention relates to a device for the simultaneous pipetting of a plurality of equal amounts of liquid in the order of magnitude of a micro-uterus.
Bisher sind Pipettiergeräte bekannt, welche ermöglichen, gleichzeitig eine Mehrzahl von Flüssigkeitsmengen zu pipettieren, jedoch eignen sich diese Geräte' nur für Elüssigkeitsmengen über 25 Mikroliter, wobei immer mehr Flüssigkeit gezogen werden muß als abgegeben wird, was einen Verlust an Flüssigkeit bedeutet.So far, pipetting devices are known which allow to pipette a plurality of amounts of liquid at the same time, but these devices are only suitable for amounts of liquid over 25 microliters, with more and more fluid being drawn in than is released, resulting in a loss of fluid means.
Diese Nachteile machen sich besonders bemerkbar in den Gebieten - z.B. Forschung über Gewebekulturen -,,wo man wegen der Kostspieligkeit der Flüssigkeiten mit Mengen in der Größenordnung des Mikroliters arbeitet.These disadvantages are particularly noticeable in areas - e.g. tissue culture research - where one is concerned about the cost of liquids with quantities on the order of microliters.

gleiche Volumen in. der Grössenordnung eines Mikroliters,same volume in the order of magnitude of a microliter,
Die beschriebenen Teile des erfindungsgemässen Pipettierge.r'äte.s sind mittels Schrauben 8 zusammengebracht und das Gerät an einem Stativ 11 fixiert»The described parts of the pipetting device according to the invention are brought together by means of screws 8 and the device fixed on a tripod 11 »
Beim Probennehinen wird die Saugkammer unter Vakuum gesetzt, wobei die Membrane gegen das Innere der Ausbuchtungen angesaugt wird und eine Flüssigkeitsmenge in die Kanüle "befördert wird, die durch das Volumen der entsprechenden Ausbuchtungen bedingt ist. /When sampling, the suction chamber is placed under vacuum, wherein the membrane is sucked against the interior of the bulges and a quantity of liquid is conveyed into the cannula "which is drawn through the volume of the corresponding bulges is conditional. /
Zur Abgabe der Proben genügt es, die Saugkanmer wieder unter Druck au setzen.It is sufficient to release the suction canister again to deliver the samples put under pressure.
In einer bevorzugten Ausführungsform der vorliegenden Erfindung (Figur2) ist die Platte 4 mit kleinen zusätzlichen Ausbuchtungen 9 versehen, die zur besseren Trennung der durch das Saugen in die Membrane verursachten Ausbuchtungen dienen.In a preferred embodiment of the present Invention (Figure 2), the plate 4 is provided with small additional bulges 9, which for better separation of the through The bulges caused by the suction in the membrane are used.
Figur 3 ist eine Gesamt ansicht einer bevorzugten Ausführungsform des erfindungsgemässen Mikropipettiergerätes. Das in Figur 3 veranschaulichte Pipettiergerät kann wie folgt benützt werden: Die Mikrotitrationsplatte 12, welche 60 mit Kulturmedien gefüllte Vertiefungen aufweist, wird auf eine Trägerplatte 13 verbracht. Die Kanülen 1 der Kanülenplatte 10 werden dann so weit herunter gelassen bis sie jeweils in die Kulturmedien eintauchen. Mittels eines lusspedals 14 wird die Saugkammer unter Vakuum gesetzt und dadurch 60 Proben in die Kanülen gefördert. Die Kanülenplatte wird hochgehoben und eine Agarplatte oder eine Platte mit einem anderen Nährmedium wird unter die Kanülenplatte 10 plaziert. Das Vakuum in der Saugkammer 5 wird entfernt, wobei- die Flüssigkeit in den Kanülen auf die Agarplatte o5.er die Nährmediumplatte fällt.Figure 3 is an overall view of a preferred embodiment of the micropipetting device according to the invention. That The pipetting device illustrated in FIG. 3 can be used as follows The microtitration plate 12, which has 60 wells filled with culture media, is placed on a carrier plate 13 spent. The cannulas 1 of the cannula plate 10 are then lowered so far that they each penetrate the culture media immerse. The suction chamber is opened by means of a release pedal 14 placed under vacuum and thereby conveyed 60 samples into the cannulas. The cannula plate is lifted up and a Agar plate or a plate with another nutrient medium is placed under the cannula plate 10. The vacuum in the The suction chamber 5 is removed, the liquid in the cannulas falling onto the agar plate or the nutrient medium plate.
