Abstract

The invention relates to a desiccator having a desiccator intermediate piece. In this case, between a desiccator lower part and a desiccator lid fitting this is inserted a cylindrical desiccator intermediate piece which is open on both sides and the seals of which fit those of the desiccator lower part and the desiccator lid. In the manner according to the patent, it is possible to enlarge the usable internal height of a conventional desiccator considerably, and virtually as desired. As a result, desiccators for bulky objects are obtained and, moreover, a reaction apparatus for a multiplicity of applications, for example for carrying out chemical reactions between solids and gases; for paper chromatography; as a vacuum recipient; for insect or plant breeding; for illumination and irradiation experiments; for corrosion experiments; and for numerous other applications.

Description

Zum Behandeln oder Inberührungbringen von Stoffen, insbesondere zum Trocknen, verwendet man im Laboratorium den Exsikkator. Dieser besteht (Fig. ) üblicherweise aus einem Exsikkator-Unter­ teil 1 und einem dazu passenden Exsikkator-Deckel 2, die gegen­ einander durch die Dichtungen 3 abgedichtet werden; ergänzt werden solche Exsikkatoren oftmals durch eine perforierte Porzellanplatte 4 und verschiedene Stutzen 5 im Exsikkator-Unterteil 1 und/oder im Exsikkator-Deckel 2.The desiccator is used in the laboratory to treat or contact substances, especially for drying. This consists ( Fig. ) Usually consists of a desiccator lower part 1 and a matching desiccator cover 2 , which are sealed against each other by the seals 3 ; Such desiccators are often supplemented by a perforated porcelain plate 4 and various connections 5 in the desiccator lower part 1 and / or in the desiccator cover 2 .

Wie aus der Fig. leicht zu ersehen ist, wird die Nutzung eines herkömmlichen Exsikkators der Höhe nach überwiegend durch die nutz­ bare Höhe des Exsikkator-Unterteils 1 bestimmt. In vielen Fällen benötigt man aber wesentlich größere Höhen, wozu man bisher spezielle Geräte herstellen lassen mußte, was zeitraubend und teuer war.As can easily be seen from the figure , the use of a conventional desiccator is largely determined by the usable height of the desiccator lower part 1 . In many cases, however, much higher heights are required, for which previously special devices had to be manufactured, which was time-consuming and expensive.

Um diese Nachteile zu vermeiden, wurde erfindungsgemäß ein Exsikka­ tor entwickelt (Fig. ), bestehend aus einem nach unten angeschlos­ senen Exsikkator-Unterteil 1, einem dazu passenden Exsikkator- Deckel 2, mit den dazu gehörenden Dichtungen 3, dadurch gekenn­ zeichnet, daß zwischen Exsikkator-Unterteil 1 und Exsikkator-Deckel 2 ein beidseitig offenes, zylindrisches Exsikkator-Zwischenstück 6 eingeschoben wird, dessen Dichtungen 3 zu denjenigen des Exsikkator- Unterteils 1 und des Exsikkator-Deckels 2 passen.In order to avoid these disadvantages, a desiccator was developed according to the invention ( Fig. ), Consisting of a downwardly connected desiccator lower part 1 , a matching desiccator cover 2 , with the associated seals 3 , characterized in that between Desiccator lower part 1 and desiccator cover 2, a cylindrical desiccator intermediate piece 6, which is open on both sides, is inserted, the seals 3 of which match those of the desiccator lower part 1 and the desiccator cover 2 .

Auf diese Weise kann man einen herkömmlichen Exsikkator in seiner nutzbaren inneren Höhe wesentlich vergrößern. In der Regel wird das Exsikkator-Zwischenstück 6 mehr als halb so hoch sein, wie die senkrechte oder nahezu senkrechte Wand des Exsikkator-Unterteils 1; die Höhe des Exsikkator-Zwischenstückes 6 ist eigentlich nur durch die mechanische Stabilität oder Bruchfestigkeit des verwendeten Werkstoffes begrenzt. Durch Verwendung oder Kombination ver­ schieden hoher Exsikkator-Zwischenstücke 6 kann der Exsikkator flexibel dem jeweiligen Verwendungszweck angepasst werden. Darüberhinaus erhält man erfindungsgemäß einen vielseitig anwend­ baren Reaktionsapparat für eine Vielzahl von Anwendungen, bei­ spielsweise zum Ausführen von chemischen Reaktionen zwischen Fest­ stoffen und Gasen; für die Papierchromatographie; als Vakuum­ rezipient; für Insekten- oder Pflanzenzüchtungen; Belichtungs- und Bestrahlungsexperimente; Korrosionsversuche; u.a.In this way, the usable inner height of a conventional desiccator can be significantly increased. As a rule, the desiccator intermediate piece 6 will be more than half as high as the vertical or almost vertical wall of the desiccator lower part 1 ; the height of the desiccator intermediate piece 6 is actually only limited by the mechanical stability or breaking strength of the material used. By using or combining different high desiccator spacers 6 , the desiccator can be flexibly adapted to the respective purpose. In addition, the invention provides a versatile reaction apparatus for a variety of applications, for example for carrying out chemical reactions between solids and gases; for paper chromatography; as a vacuum recipient; for insect or plant breeding; Exposure and radiation experiments; Corrosion tests; among others

Das erfindungsgemäße Exsikkator-Zwischenstück 6 kann seitlich angesetzte Stutzen 5 tragen, zur Aufnahme von Schliffen, Stopfen oder Hähnen, oder zum Einführen von Thermometern, Einleitungsrohren, elektrischen Leitungen, u.a.The desiccator intermediate piece 6 according to the invention can carry connecting pieces 5 attached laterally, for receiving cuts, plugs or taps, or for inserting thermometers, inlet pipes, electrical lines, etc.

In den meisten Fällen werden der untere und der obere Durchmesser des Exsikkator-Zwischenteiles 6 gleich sein. Für besondere Zwecke können diese beiden Durchmesser auch verschieden groß sein. Dadurch erhält man ein (in der Fig. nicht extra dargestelltes) Exsikkator- Zwischenstück mit z.B. konischen Seitenwänden. Der dazugehörende Exsikkator-Deckel paßt dann z.B. nur auf das konische Exsikkator- Zwischenstück, aber nicht auf das Exsikkator-Unterteil.In most cases, the lower and the upper diameter of the intermediate desiccator 6 will be the same. These two diameters can also be of different sizes for special purposes. This gives a (in FIG. Not separately shown) Desiccator intermediate piece with, for example, conical side walls. The associated desiccator cover then only fits, for example, only on the conical desiccator intermediate piece, but not on the lower desiccator part.

Gemäß Anspruch 5 kann zwischen die Dichtungen 3 des Exsikkator- Unterteils 1 und des Exsikkator-Zwischenstückes 6 eine Zwischen­ einlage 7 angebracht werden. Diese kann beispielsweise als Ring­ platte, perforierte Platte, Netz oder Heizelement ausgebildet sein, oder eine andere zweckdienliche Funktion erfüllen.According to claim 5, an intermediate insert 7 can be attached between the seals 3 of the desiccator lower part 1 and the desiccator intermediate piece 6 . This can for example be designed as a ring plate, perforated plate, mesh or heating element, or perform another useful function.

Der erfindungsgemäße Exsikkator kann aus üblichen Werkstoffen, insbesondere Glas oder Kunststoff, gefertigt werden. The desiccator according to the invention can be made from conventional materials, in particular glass or plastic.  

Die Dichtungen 3 zwischen Exsikkator-Unterteil 1 und dem Exsikka­ tor-Zwischenstück 6 können als herkömmlich geschliffene Flansch­ dichtungen ausgebildet sein, die zusätzlich gefettet werden können; oder als O-Ringdichtung; oder in anderer üblicher Form. Für den Gebrauch unter Normaldruck oder unter ganz geringem Überdruck kann man die Dichtungen 3, besonders wenn sie als Flansche aus­ gebildet sind, durch Klammern, Federn oder andere gebräuchliche Mittel zusammenhalten.The seals 3 between the desiccator lower part 1 and the Exsikka tor intermediate piece 6 can be formed as a conventionally ground flange seals that can be additionally greased; or as an O-ring seal; or in another usual form. For use under normal pressure or under very slight excess pressure, the seals 3 , especially if they are formed as flanges, can be held together by clips, springs or other common means.
