Description
Ständer mit Deckel für Reagiergefäße Stand with lid for reaction vessels
In der chemischen Labortechnik ergibt sich des öfteren die Aufgabe, chemische Reaictionen in einem Lösungsmittel mit kleinem Volumen ablaufen zu lassen. In chemical laboratory technology, the task often arises run chemical reactions in a small volume solvent.
Für diesen Zweck gibt es im Handel Reaktionsgefäße aus Kunststoff vom Typ der Eppendorf Reaktionsgefäße 3200.For this purpose, there are reaction vessels made of plastic on the market of the Eppendorf 3200 reaction tube type.
Hersteller dieser Gefäße sind z.B. Eppendorf,Hamburg, (Best.Nr. 3200) oder W.Sarstedt, Kunststoffspritzgußwerk, 5223 Nümbrecht-Rommelsdorf (Best.Nr 39/10A oder (kleineres Format:) Nr.30/8.Manufacturers of these vessels are e.g. Eppendorf, Hamburg, (Order No. 3200) or W.Sarstedt, plastic injection molding plant, 5223 Nümbrecht-Rommelsdorf (order number 39 / 10A or (smaller format :) No. 30/8.
will man chemische reaktionen unter erhöhter Temperatur in ebengenannten Reaktionsgefäßen durchführen, z.B. durch Erhitzen im wasserbad oder im Trockenschrank, so entwickelt das Lösungsmittel in den Reaktionsgefäßen einen cterartigen Dampfdruck, daß die Deckel der Reaktionsgefäße aufspringen und das Lösungsmittel verdampft oder sogar herausgeschleudert wird. werner besteht beim Erhitzen im Wasserbad die Gefahr, daß sich in die durch Dampfdruck geöffneten Reaktionsgefäße wasser ergießt. if you want chemical reactions at elevated temperature in the aforementioned Carry out reaction vessels, e.g. by heating in a water bath or in a drying cabinet, so the solvent in the reaction vessels develops a cter-like vapor pressure, that the lids of the reaction vessels pop open and the solvent evaporates or is even thrown out. When heating in a water bath, there is a risk of that water pours into the reaction vessels opened by steam pressure.
Andererseits gibt es für den obengenannten Zweck bisher nur die Möglichkeit, die Reaktionspartner in Glasampullen einzuschmelzen. Dies ist besonders mühsam, wenn man z,B, iOO Fraktionen einer Säulenchromatographie hydrolisieren und anschließend analytisch untersuchen will. On the other hand, for the above-mentioned purpose there has only been the possibility to date to melt the reactants in glass ampoules. This is particularly troublesome if you hydrolyze, for example, 100 fractions of a column chromatography and then want to analyze analytically.
Die vorliegende Erfindung betrifft einen Ständer mit befestigbarem Deckel, passend für Reagiergefäße vom Typ der Eppendorf Zentrifugenröhrchen. Mit Hilfe des auf dem Gestell befestigbaren Deckels läßt sich auf die Deckel der Reaktionsgefäße ein Druck ausüben, und ein unerwünschtes Aufspringen bei Temperaturen bis ca. i200 ist ausgeschlossen. The present invention relates to a stand with an attachable Lid, suitable for reaction vessels of the Eppendorf centrifuge tube type. With Help the on the frame attachable cover can be on the Apply pressure to the lid of the reaction vessel and cause it to pop open unintentionally at temperatures up to approx. i200 is excluded.
Abb. zeigt den Ständer von der Seite. Er besteht aus folgenden Einzelteilen: a) einem Ständer (i) mit vier Füßen (2) und vorzugsweise mit vier kopfstehenden Schrauben (3), die in das Gestell eingeschraubt sind, b) Erfindungsgemäß aus einem befestigbaren Deckel (4), der vorzugsweise mit vier Löchern versehen ist, und zwar dergestalt, daß die kopfstehenden Schrauben (3) durch sie hindurchpassen. Und c) Vorzugsweise aus vier Flügelschrauben (5), mit denen man den deckel (4) auf die Reaktionsgefäße (6) preßt. Fig. Shows the stand from the side. It consists of the following parts: a) a stand (i) with four feet (2) and preferably four upside down Screws (3) which are screwed into the frame, b) according to the invention from one attachable cover (4), which is preferably provided with four holes, namely in such a way that the upside-down screws (3) fit through them. And c) Preferably from four wing screws (5) with which you can put the cover (4) on the Presses reaction vessels (6).
Abb.2 seigt den Stander von oben. Links oben sieht man die Deckel von i2 Reaktionsgefäßen (7). Ferner sieht man die töcher für die Reaktionsgefäße (ö). Die vier schrauben (9) für Verankerung der Füße des Gestells sowie die für Befestigung der Flügelschrauben (3) sind eingezeichnet. Fig.2 shows the stand from above. At the top left you can see the lids of i2 reaction vessels (7). You can also see the holes for the reaction vessels (ö). The four screws (9) for anchoring the feet of the frame and those for The fastening of the wing screws (3) are shown.
Hat man mir wenige Proben zur Untersuchung, so empfiehlt es sich, den Ständer mit mehreren leeren Reaktionsgef. If you have a few samples for examination, it is advisable to the stand with several empty reaction vessels.
zu füllen, damit ein paralleles Aufliegen des Deckels auf dem Ständer gewährleistet ist.to fill so that the lid rests parallel on the stand is guaranteed.
uer Deckel des geschilderten Ständers kann abgesehen von den beschrieben Flügelschrauben auch mit Klamnern jeglicher iirt, oder auch mit Hilfe eines Scharniers am Ständer befestigt werden. The cover of the stand described can be described apart from the Wing screws also with any kind of clamps, or with the help of a hinge attached to the stand.
Das Material des Ständers sowie des Deckels besteht vorzugsweise aus einer Legierung (z.. Messing), die weitgegend gegen Salzsäuredämpfe resistent ist. Die Gründe für die Wahl des Materials seien anhand folgender rationellen Arbeitsweise iiei einer hydrolyse dargelegt: Nach Hydrolyse mit Salzsäure entnimmt man den verschlossenen Ständer mit Asbesthandschuhen dem Trockenschrank, entfernt den Deckel, öffnet die Reaktionsgefäße und gefriert die Proben bei -50°. Sie werden dann sofort in einen Exsikkator mit Natriumhydroxid und Kieselgel oder unter eine Lyophilisatorhaube gebracht und unter Vakuum getrocknet. The material of the stand and of the cover is preferably made Made of an alloy (e.g. brass) that is largely resistant to hydrochloric acid vapors is. The reasons for choosing the material are based on the following rational working method iiei a hydrolysis set out: After hydrolysis with hydrochloric acid, the closed one is removed Stand with Asbestos gloves in the drying cabinet, removed the lid, opens the reaction vessels and freezes the samples at -50 °. You will then immediately in a desiccator with sodium hydroxide and silica gel or under a lyophilizer hood brought and dried under vacuum.
Die Größe des Ständers ergibt sich vorzugsweise zu 6 oder 5 Reihen mit je 10 Löchern, so daß das Gestell in einer handlichen Dimension bleibt und in einen handelsüblichen Exsikkator oder unter eine myophilisatorhaube gebracht werden kann. Die Maße der Abb.2 sind nur richtungsweisend und sind naturgemäß abzuändern bei kleineren Reagiergefäßen (z.B. Reaktionsgefäße der Firma Sarstedt, Best.Nr. 30/8). The size of the stand is preferably 6 or 5 rows with 10 holes each, so that the frame remains in a handy dimension and in a commercially available desiccator or under a myophilizer hood can. The dimensions in Fig. 2 are only indicative and must of course be changed for smaller reaction vessels (e.g. reaction vessels from Sarstedt, order no. 30/8).
Besonderer Vorteil des Geräts: Müssen die Reaktionsgefäße rasch abgekühlt werden, kann man den verschlossenen in einem bereitstehen Eimer mit Eiswasser untertauchen, Ständer ohne daß wasser in die Gefäße eindringt. Special advantage of the device: The reaction vessels have to be cooled down quickly you can submerge the closed one in a bucket with ice water, Stand without water entering the vessels.
