Description
Zentrifugiergefäß mit Sammelansatz Zentrifugiergefäße dienen dazu, Substanzen auf Grund ihres verschiedenen - spezifischen Gewichtes zu trennen. Um das interessierende Trennungsprodukt besser abmessen bzw. erkennen zu können, bringt man an den Zentrifugiergefäßen häufig sog. Sammelansätze an, die meist einen geringeren Durchmesser aufweisen als das Zentrifugiergefäß und eine verjüngte Verlängerung desselben darstellen. Die Erfindung betrifft eine Verbesserung derartiger Zentrifugierröhrchen, die vor allen Dingen. dann in Erscheinung tritt, wenn die Zentrifugierung in einer solchen Lage des Röhrchens erfolgt, daß dessen Achse mit der Drehachse der Zentrifuge nicht einen Winkel von go°, sondern einen kleineren Winkel bildet Bekanntlich erfolgt der Trennungsprozeß zweier Substanzen verschiedenen spezifischen Gewichtes schneller, wenn das Gefäß im spitzen Winkel zur Zentrifugenachse angeordnet ist, weil dann die schwereren Teilchen geschlossen an der der Zentrifugenachse entfernten Seite des Gefäßes entlang wandern und ihre Bewegungstendenz gewissermaßen summieren. Bei dem erfindungsgemäßen Röhrchen ist das Sammelansatzgefäß derart exzentrisch zur Achse des Zentrifugiergefäles an dieses angesetzt, daß ein Teil der Innenwand des Zentrifugiergefäßes geradlinig in den anschließenden Teil der Innenwand des Sammelansatzes übergeht, wie es die Abbildung andeutet. Die Teilchen entfernen sich zunächst in Richtung der Pfeile 1 von der Zentrifugenachse 2 und wandern dann parallel zur Wandung 3 des Zentrifugiergefäßes 4 in Richtung der Pfeile 5. Da nach der Erfindung der Sammelansatz 6 exzentrisch angeordnet ist, wandern die Teilchen in sich tung der Pfeile 5 unmittelbar in das Sammelgefäß 6 hinein, ohne aus ihrer - Bevegungsrichtung abgelenkt zu werden. Würde das SammelgefäS 6 zentral zum Gefäß 4 angeordnet sein, so würden die Teilchen vor Eintritt in das Gefäß 6 ihre Wegrichtung ändern müssen. Die Folge wäre eine Stauung, eine ungewollte Ansammlung in der Wegkrümmung oder eine die Trennung aufhebende Wirbelbildung.Centrifuge vessel with collecting attachment Centrifuge vessels are used to To separate substances based on their different specific gravity. Around To be able to measure or recognize the separation product of interest better, brings so-called collection approaches are often found on the centrifuge vessels, which are usually smaller Have a diameter than the centrifuge tube and a tapered extension represent the same. The invention relates to an improvement of such centrifuge tubes, above all else. then occurs when centrifugation in a such a position of the tube takes place that its axis coincides with the axis of rotation of the centrifuge does not form an angle of go °, but rather a smaller angle the process of separating two substances of different specific gravity faster, if the vessel is arranged at an acute angle to the centrifuge axis, because then the heavier particles closed on the side remote from the centrifuge axis wander along the vessel and, as it were, add up their tendency to move. at the tube according to the invention, the collecting vessel is so eccentric to Axis of the Zentrifugiergefäles attached to this that part of the inner wall of the Centrifuge tube straight into the adjoining part of the inner wall of the collection attachment passes over, as the figure suggests. The particles initially move away in Direction of arrows 1 from centrifuge axis 2 and then move parallel to the wall 3 of the centrifuge vessel 4 in the direction of arrows 5. Since according to the invention of Collection approach 6 is arranged eccentrically, the particles migrate in the device Arrows 5 directly into the collecting vessel 6 without leaving their - direction of movement to be distracted. If the collecting vessel 6 were to be arranged centrally to the vessel 4, so the particles would have to change their direction of travel before entering the vessel 6. The consequence would be a congestion, an unwanted accumulation in the bend or a vortex formation that nullifies the separation.
Da es bei den erfindungsgemäßen Röhrchen wichtig ist, nach welcher Richtung das Sammelgefäß 6 exzentrisch in Verlängerung des Rohres 4 angeordnet ist, wird nach der Erfindung die Halterung des Zentrifugierröhrchens 4 so ausgebildet, daß nur eine bestimmte Stellung des Röhrchens möglich ist. Im vorliegenden Beispiel erfolgt dies dadurch, daß die Hülse 7 eine Bodenplatte8 trägt, die mit einer exzentrischen Lochöffnun 9 ausgestattet ist. Ein Einsetzen des Zentrifugierröhrchens 4 ist also nur möglich, wenn das Sammelgefäß in das Loch 9 eingeführt wird, d. h. wenn die Lage des Röhrchens richtig gewählt ist. Since it is important with the tubes according to the invention, after which Direction the collecting vessel 6 is arranged eccentrically in the extension of the pipe 4, according to the invention, the holder of the centrifuge tube 4 is designed so that only a certain position of the tube is possible. In this example this is done in that the sleeve 7 carries a bottom plate 8 with an eccentric Lochöffnun 9 is equipped. Insertion of the centrifuge tube 4 is therefore only possible if the collecting vessel is inserted into the hole 9, d. H. if the The correct position of the tube is selected.
Die Erfindung läßt sich selbstverständlich auch auf solche Zentrifugiergefäße übertragen, bei denen der Sammelansatz am oberen Ende des Gefäßes angeordnet ist, um einen leichteren Bestandteil besser nachweisen bzw. messen zu können. In diesem Falle ist die unbebinderte Wegbahn auf der der Zentrifugenachse zugewendeten Seite vorzusehen. The invention can of course also be applied to such centrifugation vessels transferred, in which the collecting attachment is arranged at the upper end of the vessel, around better prove or measure a lighter component can. In this case the unbound path is on the centrifuge axis to be provided on the facing side.
Besitzt das Sammel- oder Meßgefäß flachen, z. B. ovalen Querschnitt, so wird das Gefäß derart angeordnet, daß die große Querschnittsachse in eine Ebene mit der Zentrifugendrehachse zu liegen kommt. Auf diese Weise erhält man eine bessere Trennung der auf und ab steigenden Flüssigkeitsteile. Has the collection or measuring vessel flat, z. B. oval cross-section, so the vessel is arranged in such a way that the major cross-sectional axis is in one plane comes to rest with the centrifuge axis of rotation. That way you get a better one Separation of the rising and falling parts of the liquid.
