KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Gegenstand vorliegender Erfindung ist ein Apparat zum genauen Abmessen einer bestimmten Flüssigkeitsmenge.The present invention relates to an apparatus for accurately measuring a specific one Amount of liquid.
Die Zeichnung stellt den Erfindungsgegenstand in einer beispielsweisen Ausführungsform dar. The drawing represents the subject matter of the invention in an exemplary embodiment.
Durch den Stopfen α einer gewöhnlichen, in Gebrauch befindlichen Flasche b geht unter dichtem Abschlüsse eine Pipette c, die mitThrough the stopper α of an ordinary bottle b in use, a pipette c, which is tightly sealed, goes with it
ίο ihrem einen Ende in die Flüssigkeit eingetaucht, sowie aus der Flasche herausgezogen werden kann.ίο one end immersed in the liquid, as well as can be pulled out of the bottle.
Am oberen Ende besitzt die Pipette c einen ausgebauchten Teil d, damit sie nicht ganz inAt the upper end, the pipette c has a bulged part d so that it does not go all the way in
die Flasche gedrückt werden kann. Über dieser Ausbauchung d ist die Pipette c durch einen Stopfen e verschließbar. Unten endigt die Pipette in einen massiven Teil f, der zwecks Abdichtung der Flasche beim Entleeren der Pipette etwas länger als der Hals der Flasche ist. Am unteren Ende des Hohlraumes der Pipette befindet sich eine kleine Öffnung g. Der Inhalt der Röhre von dieser Öffnung an bis zu dem oberen Rande der Ausbauchung d ist bekannt oder eingeteilt; es können so Pipetten verschiedenen Inhalts angefertigt werden.the bottle can be squeezed. The pipette c can be closed by a stopper e above this bulge d . At the bottom, the pipette ends in a solid part f, which is slightly longer than the neck of the bottle for the purpose of sealing the bottle when the pipette is emptied. At the lower end of the cavity of the pipette there is a small opening g. The contents of the tube from this opening to the upper edge of the bulge d are known or classified; pipettes with different contents can be made in this way.
Die Pipette wird folgendermaßen gebraucht: Die Flasche wird gefüllt,, die Pipette eingeschoben und oben verkorkt. Dann zieht man die Pipette c durch den Stopfen a so weit nach oben, daß die Öffnung g innerhalb der Flasche b in der Nähe des Stopfens α liegt, kehrt die Flasche um und füllt die Pipette durch die Öffnung g mit Flüssigkeit. Nun zieht man die Pipette an der umgekehrten Flasche weiter heraus, und zwar so weit, daß sich die Öffnung g innerhalb des Stopfens a befindet, so daß Flüssigkeit weder zu- noch abfließen kann. Hierauf kann man durch Entfernen des Stopfens e die Flüssigkeit in ein kleines Glas entleeren oder sie auch direkt aus der Pipette zu sich nehmen. Will man die Pipette nur zum Teil gefüllt haben, so kann man eine beliebige Flüssigkeitsmenge durch Lüften des Stopfens e. herauslassen, wenn man die Flasche b aufrecht stellt. Kleinere Pipetten von J/2 bis 2 ecm dienen als Ersatz für die jetzt gebräuchlichen Tropfgläser, die viele Nachteile aufweisen. So sind z. B. die Tropfen je nach dem Inhalt des Tropfglases oder der Abtropffläche verschieden groß.The pipette is used as follows: The bottle is filled, the pipette is pushed in and the top is corked. The pipette c is then pulled up through the stopper a so far that the opening g within the bottle b is close to the stopper α , the bottle is inverted and the pipette is filled with liquid through the opening g. Now pull the pipette on the inverted bottle further out, to the extent that the opening g is located inside the stopper a , so that liquid can neither flow in nor out. You can then empty the liquid into a small glass by removing the stopper e or take it directly from the pipette. If you want to have the pipette only partially filled, you can add any amount of liquid by venting the stopper e. let out when the bottle b is placed upright. Smaller pipettes from J / 2 to 2 ecm serve as a substitute for the now common dropper glasses, which have many disadvantages. So are z. B. the size of the drops depending on the contents of the dropper glass or the drainer.
