Description

Verfahren und Vorrichtung zum Rollen von Reagenzgläsern u. dgl. zwecks Verteilung fester Nährböden auf der gesamten Innenfläche der Röhren Das Ausrollen fester Nährböden, welche zu diesem Zweck zeitweilig verflüssigt werden, in Reagenzgläsern o. dgl. zwecks gleichmäßiger Verteilung des Nährbodens in dünner Schicht auf der ganzen Innenfläche, geschah bisher durch einfaches Drehen mit der Hand oder durch mit der Hand betriebene Apparaturen. Hierbei war es nötig, ein Kühlmittel zu Hilfe zu nehmen (Eis oder Wasser). Dies hatte aber unangenehme Nebenerscheinungen im Gefolge. So mußte z. B. der Wattestopfen zur Verhütung des Anfeuchtens mit einer Gummikappe überzogen werden. Die Herstellung einwandfreier Rollröhrchen war auf dem geschilderten Wege umständlich und schwierig.Method and device for rolling test tubes and the like for the purpose of Distribution of solid nutrient media over the entire inner surface of the tubes solid culture media, which are temporarily liquefied for this purpose, in test tubes o. The like. For the purpose of even distribution of the nutrient medium in a thin layer on the entire inner surface, was previously done by simply turning by hand or by hand operated equipment. Here it was necessary to use a coolant to take (ice or water). But this had unpleasant side effects as a result. So had to z. B. the cotton plug to prevent wetting with a rubber cap be coated. The production of flawless roll tubes was as described Paths cumbersome and difficult.

Die im folgenden beschriebene Apparatur versucht diese Nachteile auszumerzen. Auf einem langen Block i sind zu beiden Seiten Scheiben 2 korrespondierend angebracht. Die gegenüberliegenden Scheiben sind durch eine Achse 7 miteinander verbunden. Die Scheiben werden durch einen Motor S o. dgl. mittels Schnurübertragung oder ähnlichem durch Schnurscheiben 3, 8 in schnell drehende Bewegung versetzt. Zwischen zwei gegenüberliegenden Paaren von Scheiben legt man ein Reagenzglas 6, das von den rotierenden Scheiben 2 in schnelle Drehung versetzt wird. Eine auf dem Röhrchen mitrollende Scheibe verhindert das Abgleiten des Röhrchens. Das Rollen der Röhrchen kann auch dadurch bewerkstelligt werden, daß das Röhrchen zwischen zwei sich drehende Spitzen gespannt wird. Der in der Reagenzröhre befindliche flüssige Nährboden schlägt sich gleichmäßig auf der inneren Wandung der Röhre nieder.The apparatus described below tries to eliminate these disadvantages. Disks 2 are correspondingly attached to both sides of a long block i. The opposing disks are connected to one another by an axle 7. the Discs are driven by a motor S or the like by means of a cord transmission or the like set in rapidly rotating motion by cord pulleys 3, 8. Between two opposite Pairs of disks place a test tube 6, which is from the rotating disks 2 is set in rapid rotation. A disk rolling along on the tube prevents it the sliding of the tube. The rolling of the tubes can also be accomplished thereby be that the tube is stretched between two rotating tips. Of the The liquid nutrient medium in the reagent tube will open evenly the inner wall of the tube down.

Werden die Achsen hülsenförmig gestaltet, dann können die Reagenzröhrchen durch Einsetzen in diese Hülsen gerollt werden. Die Hülse muß allerdings derartig konstruiert sein, daß sich das Reagenzglas gut einschieben und bei der Drehung mitbewegen läßt.If the axes are designed in the shape of a sleeve, then the reagent tubes be rolled by inserting into these sleeves. The sleeve, however, must be of this type be constructed so that the test tube can slide in well and move with the rotation leaves.
