Description

Gasbürette mit Kühlmantel. Die bisher benutzten Büretten bestehen aus einem in 5o oder ioo ccm geteilten Rohr, welches von einem Kühlmantel umgeben ist und unten durch einen Schlauch mit einer Niveauflasche verbunden wird. Die Abmessung des gewünschten Volumens, 50 oder =oo ccm, wurde in der Weise vorgenommen, daß etwas mehr Gas als nötig eingesaugt wurde und der Überschuß durch Heben der Niveauflasche und Einstellung ihres Niveaus auf den Nullpunkt herausgedrückt wurde.Gas burette with cooling jacket. The burettes used so far exist from a tube divided into 50 or 100 ccm, which is surrounded by a cooling jacket and is connected at the bottom by a hose to a level bracket. The dimension of the desired volume, 50 or = oo ccm, was made in such a way that something more gas than necessary was sucked in and the excess by lifting the level bottle and setting their level to zero has been pushed out.

Nach der vorliegenden Erfindung ist die Gasbürette a, die zweckmäßig unten verengt und kapillar ausgebildet ist, am Nullpunkt abgeschnitten und der Schlauch e der Niveauflasche nicht an der Gasbürette direkt, sondern an "dem mit Wasser gefüllten Mantel b vermittels Gummistopfens und Glasrohrs angesetzt. Das Abmessen des Volumens geschieht nunmehr in der Weise, daß dem Gasstrom so lange Zutritt gewährt wird, bis die erste Gasblase aus dem unteren Bürettenende in das Mantelrohr übertritt. Die Bürette enthält dann ioo bzw. 5o ccm.According to the present invention, the gas burette a is useful is narrowed and capillary at the bottom, cut off at the zero point and the hose e of the level bottle not directly on the gas burette, but on the one filled with water Sheath b attached by means of a rubber stopper and glass tube. Measuring the volume now happens in such a way that the gas flow is granted access as long as until the first gas bubble passes from the lower end of the burette into the jacket tube. The burette then contains 100 or 50 ccm.

Die Niveauflasche wird zweckmäßig mit einem Füllstrich in der Art versehen, daß das Niveau der Absperrflüssigkeit in ihr bei vollständig gasgefüllter Bürette einerseits diesen Strich erreicht, änderseits mit dem unteren Ende der Bürette eben abschneidet. Der Zeitverlust beim Einstellen des Nullpunktes und der dabei mögliche Ablesefehler kommen also bei dieser Vorrichtung in Wegfall.The level bottle is expediently provided with a filling line like provided that the level of the shut-off liquid in it when fully gas-filled Burette reaches this line on the one hand, and on the other hand with the lower end of the burette just cut off. The loss of time when setting the zero point and thereby possible reading errors are therefore eliminated with this device.
