Abstract:
1. Device for centrifuging various samples of a product or a mixture of products which are chemical or biological, which is intended to be positioned on a horizontal working plane including an available area (S) that is less than or equal to about 0.4 m 2 , in order to cooperate with a laboratory analyzer mounted in proximity to the working plane for automatically performing biological or chemical reactions according to a predetermined protocol, the external useful height of which centrifuging device is less than or equal to about 20 cm, comprising in a casing: a vessel which is open at the top and contains a vertical central shaft driven in rotation by a rotary driving means, a horizontal plate, mounted interlocked in rotation on the central shaft and provided with arrangements for parallel mounting of two swing trays, in proximity to each other, for supporting two sample-receptacle holders which can pivot freely about a horizontal axis in order to assume a horizontally inclined position during the rotation of the plate, and means for indexing the position of the plate each time the plate stops, in order to position said swing trays at predetermined sites; wherein the horizontal plate is provided with through orifices that extend from the bottom of the horizontal plate to the top of the horizontal plate adapted for the mounting of tubes; and wherein the device is adapted to automatically receive tubes from the laboratory analyzer and to automatically permit the laboratory analyzer to retrieve tubes from the laboratory analyzer to perform biological or chemical reactions.
