Saugpipette für aräometrsche Messungen u. dergleichen. Gegenstand der Neuerung ist eine Saugpipette,in deren Inneren an. der angesaugten Flüssigkeitsprobe Dichte messungen mit Aräometern (Senkwaagen)rchemische Reaktionen oder sonstige Prüfungen durchgeführt werden· Bekannt sind , insbesondere zum Prüfen von Batterie-Säuren und -Laugen,Saugpipetten aus Glas oder Kunststoff.Am oberen Ende eines meist rohrförmigen Gehäuses befindet sich ein Saugball,am unteren Ende ein Verschlußstopfen mit dünnerem Saugrohr zum Ansaugen der zu prüfenden Flüssigkeit· In dem rohrförmigen,glasklaren Gehäuse befindet sich das Aräometer ( Senkwaage )· In der Praxis hat es sich gezeigt,daß sich der Saugball gern im Rohr lockert und heraus fallen kann.Denn diese Pipetten werden bei Gebrauch am Saugball gehalten und bei Nichtgebrauch am Ball in einer Gabel aufgehängt,damit das Gerät austropfen kann« Eine neuerungsgemäße Ausführung wird als Beispiel in der Zeichnung im Längsschnitt in der Gebrauuchslage dargestellt und beschrieben,wie folgt ι Der Saugbali 1 ist mit dem Gehäuse 2 durch schweissen oder kleben fest verbunden. Das Aräometer 4 wird durch Entfernung des lösbaren Stopfens 3 in das Gehäuse 2 eingebracht. Bei den bekannten Ausfahrungen wird das Aräometer 4 durch das Ausziehen des Saugballs 1 in das Rohrgehäuse 2 gebracht· Der S^ugball 1 kann auch,wie aus der Zeichnung ersichtlich. ist,mit dem Rohr 2 aus einem Stück bestehen. Schutzansprüche :Suction pipette for aerometric measurements and the like. The object of the innovation is a suction pipette, inside of which an. of the sucked liquid sample, density measurements with hydrometers (lowering scales) chemical reactions or other tests are known, especially for testing battery acids and alkalis, suction pipettes made of glass or plastic. At the upper end of a mostly tubular housing there is a suction ball, At the lower end there is a plug with a thinner suction tube for sucking in the liquid to be tested.The hydrometer (lowering balance) is located in the tubular, crystal-clear housing. Because these pipettes are held on the suction ball when in use and hung on the ball in a fork when not in use, so that the device can drip out firmly connected to the housing 2 by welding or gluing. The hydrometer 4 is inserted into the housing 2 by removing the detachable stopper 3. In the known experiences, the hydrometer 4 is brought into the tubular housing 2 by pulling out the suction ball 1. The suction ball 1 can also, as can be seen from the drawing. is to be made with the tube 2 in one piece. Protection claims: 1. Saugpipette für aräometrtsche Messungen und dergleichen, dadurch gekennzeichnet,daß der Pipettenkörper (2) mit dem Saugball (1) durch verkleben oder ve^chweissen unlösbar verbunden ist·1. Suction pipette for aräometric measurements and the like, characterized in that the pipette body (2) with the Suction ball (1) cannot be removed by gluing or welding connected is· 2. Ssugpipette nach Anspruch 1 , dadurch gekennzeichnet, daß Pipet-cangehäÄse (2) und Saugball (l)aus einem Stück bestehen2. Ssugpipette according to claim 1, characterized in that that the pipet can housing (2) and suction ball (l) are made from one piece exist
