Description

Die Erfindung betrifft ein verschließbares Mantelröhrchen zur Aufnahme eines mit einem dichten Abschluß versehenen Zentrifugierröhrchens. The invention relates to a closable jacket tube for receiving a centrifuge tube provided with a tight seal.

Zentriefugierröhrchen, wie sie beispielsweise im deutschen Gebrauchsmuster 1 682 599 erläutert sind, müssen vor dem Zentrifugieren oder vor der Behandlung ihres Inhalts mit chemischen, insbesondere klinischen Zusätzen normalerweise irgendwo, z. B. in einem Reagenzglasgestell, abgestellt werden. Centrifugation tubes, such as those in the German utility model 1 682 599 must be carried out prior to centrifugation or prior to treatment their content with chemical, especially clinical additives usually somewhere, z. B. in a test tube rack.

Dies besonders dann, wenn das Röhrchen auf dem Transport defekt geworden ist und somit seine Handberührung eine besondere Gefahr darstellt. Dann läßt sich das Aufstellen häufig nicht schnell genug und auch nicht mit jener Sicherheit erreichen, die erforderlich ist, um das Auslaufen der unter Umständen Bakterien enthaltenden Substanz zu vermeiden, vor allem dann, wenn ein Reagenzglasgestell nicht zur Verfügung steht.This is especially true if the tube has become defective in transit and touching it with the hand represents a particular danger. Then you can often do not reach the erection quickly enough and also not with the certainty that which is necessary to prevent the leakage of bacteria that may contain Avoid substance, especially if a test tube rack is not available stands.

Dieser Nachteil soll erfindungsgemäß dadurch beseitigt werden, daß als Abschluß für das Mantelröhrchen eine Schraubkappe dient, deren Innenfläche als Sitz für das runde Ende des Zentrifugierröhrchens und dessen Außenfläche als Standfläche ausgebildet ist. This disadvantage is to be eliminated according to the invention in that a screw cap serves as a conclusion for the jacket tube, the inner surface of which is used as Seat for the round end of the centrifuge tube and its outer surface as a stand is trained.

An Hand der Zeichnung ist die Erfindung beispielsweise erläutert. The invention is explained by way of example with the aid of the drawing.

Danach trägt ein Zentrifugierröhrchen 1 an seinem offenen Ende ein Außengewinde 1 a zur Aufnahme eines dicht schließenden Schraubdeckels 2. Es ist unter Bildung eines Luftspaltes 3 von einem Mantelröhrchen 4 umgeben, auf dessen offenes Ende ebenfalls dichtend eine Schraubkappe 5 aufgesetzt ist. Thereafter, a centrifuge tube 1 enters at its open end External thread 1 a for receiving a tightly fitting screw cap 2. It is with the formation of an air gap 3 surrounded by a jacket tube 4 on which open end, a screw cap 5 is also sealingly attached.

Ihre Außenfläche 5 a ist als Standfläche ausgebildet.Your outer surface 5 a is designed as a standing area.

Außerdem weist sie eine zentrische Ausnehmung auf, die als Sitz 5 b des abgerundeten Endes 1 b des Röhrchens 1 dient.In addition, it has a central recess, which is used as the seat 5 b of the rounded end 1 b of the tube 1 is used.

Kommt eine solche Röhrchenkombination in eine Untersuchungsanstalt, z. B. ein Labor, so kann das Zentrifugierröhrchen 1 durch Abschrauben der Kappe 5 von dem Mantelröhrchen 4 aus diesem herausgenommen und sogleich ohne jegliche andere Hilfsmitttel mit der Kappe 5 des Mantelröhrchens 4 als Ständer an jedem beliebigen Platz aufgestellt werden. If such a combination of tubes comes to an examination institute, z. B. a laboratory, the centrifuge tube 1 can be removed by unscrewing the cap 5 taken out of the jacket tube 4 from this and immediately without any other tools with the cap 5 of the jacket tube 4 as a stand on any Place to be set up.

Die Anordnung des Deckelgewindes 1 a auf der Außenseite des Zentrifugierröhrchens 1 gestattet stets dessen restlose Entleerung. Der Zwischenraum zwischen den beiden Röhrchen und 4 kann zur Aufnahme eines Dichtungsmittels, beispielsweise in Form von Watte Zellstoff od. dgl., dienen. In jedem Falle bildet er ein Luftpolster, das unter gegebenen Voraussetzungen auch zur Dichtung des Zentrifugierröhrchens beitragen und zu dessen Schutz gegen Druck oder Schlag von außen dienen kann. The arrangement of the lid thread 1 a on the outside of the centrifuge tube 1 always allows it to be completely emptied. The space between the two Tubes and 4 can accommodate a sealant, for example in the form of cotton wool or cellulose. The like., Serve. In any case it forms a cushion of air, this, under the given conditions, also to seal the centrifuge tube and can serve to protect it against external pressure or impact.
