The bracket 3 is suspended in the transparent pro-pin 7 in a centrifugal head 8 by means of the state it has reached. In this case, the test material contained in bengefäß is the beaker 4 made of transparent such a centrifuge by the German patent plastic glass, so that through window 9 of the vessel specification 934 201 became known. In doing so, the Ha'itegestells 5 are made, the lower parts of the individual areas, so the known effect of a stroboscope is visible. A photo transducer 10 is arranged in the cover 2 above the area of the window frame, an approximately constant pattern 9, and a stroboscopic lamp was optically held in place exactly vertically below it.

Durch diese Erfindung ist es dann auf einfache Weise möglich, die Zeitdausr des Zentrifugierens durch den Zentrifugiereffekt selbst zu bestimmen und das aus dem Fotowandler 10 gewonnene Signal zum Abschalten der Zentrifuge zu benutzen.With this invention it is then possible in a simple manner to reduce the centrifugation time to be determined by the centrifugation effect itself and the signal obtained from the photo converter 10 to switch off the centrifuge.
Selbstverständlich ist auch ein ander, r Aufbau des GefäÖtrUgers möglich, Für die Erfindung wesentlich ist nur daß Durchbrüche oder Fenster vohanden sind, durch die die Lichtimpulse der Stroboskoplampe hindurchtreten können.Of course, a different construction of the vessel is also possible, which is essential for the invention The only thing is that there are openings or windows through which the light pulses from the strobe lamp can pass through.
