Description

Zylindrischer Einsatzkörper für Serumzentrifugen Es ist beim FiItrieren von Flüssigkeiten bekannt, insbesondere zur Trinkwasserreinigung, innerhalb eines rohrförmigen Gefäßes einen -porösen Einsatz anzuordnen, durch den das Wasser hindurchgepreßt wird.Cylindrical insert for serum centrifuges. It is filtering of liquids known, especially for drinking water purification, within a tubular vessel to arrange a porous insert through which the water is pressed will.

Ein ähnlich ausgestalteter Filterkörper wird nach der Erfindung als Einsatz für Serumzentrifugen benutzt. Der Einsatz besteht aus zwei ineinander festsitzenden, am Ende geschlossenen Behältern, von denen der innere ein Filterkörper aus Ton oder ähnlichem Baustoff ist, während der äußere Aufnahmekörper aus Glas besteht. A similarly designed filter body is according to the invention as Insert used for serum centrifuges. The insert consists of two tightly fitting, at the end closed containers, the inner of which has a filter body made of clay or A similar building material is, while the outer receiving body is made of glass.

Es ist bereits vorgeschlagen worden, Serumflüssigkeiten in gewöhnlichen Bechern auszuschleudern. Im vorliegenden Fall aber handelt es sich um die Filtration solcher Flüssigkeiten, die bekanntlich in der bisher iiblichen Weise außerordentlich langer Zeiträume bedarf. It has already been suggested to use serum fluids in ordinary Ejecting cups. In the present case, however, it is about filtration such liquids, which are known to be extraordinary in the usual way long periods of time.

Die Erfindung ist auf der Zeichnung beispielsweise dargestellt. The invention is shown in the drawing, for example.

Der zur Aufnahme der zu filtrierenden Flüssigkeit bestimmte Behälter ist ein an einem Ende geschlossener, abgerundeter Tonzylinder c mit oberem Flansch. Dieser Tonzylinder hängt in einem Ring b, der auf den Rand eines gleichgeformten Glasbehälters a aufgesetzt ist. Dieser Einsatzbehälter wird in iiblicher Weise in eine Becherschleudermaschine ot dgl. (Zentrifuge) eingesetzt, die in hohe Umdrehung versetzt wird. Der Tonzylinder kann für grobdisperse Suspensionen ohne weiteres benutzt werden. Zum Filtieren von hochdispersen Colloiden wird er mit einer entsprechenden halbdurchlässigen Membran, z. B. Collodium, überzogen. The container designed to hold the liquid to be filtered is a rounded clay cylinder c closed at one end with an upper flange. This clay cylinder hangs in a ring b, which on the edge of a similarly shaped Glass container a is attached. This insert container is conventionally used in a cup centrifuge ot the like. (centrifuge) used, which in high rotation is moved. The clay cylinder can easily be used for coarsely dispersed suspensions to be used. For filtering highly dispersed colloids, it is used with an appropriate semi-permeable membrane, e.g. B. Collodion, coated.
