First Claim
1. Device for processing samples of blood products contained in tubes closed by means of bungs and loaded into cassettes, of the type incorporating means of agitation capable of agitating the tubes, together with means of sampling capable of collecting at least one sample from a pre-agitated tube, characterised in that it includes transfer means (10) designed to move the cassettes (12) individually on a pre-determined path, and in that the means of agitation (30) incorporate at least one pick-up mechanism (32) designed to pick up at least one selected tube (18) from a cassette (12) immobilised on the path, to remove said tube away from the cassette, to agitate the tube and to replace it in the cassette, and in that the sampling means (34) include at least one needle (148) designed to draw a given sample quantity from the tube that has been pre-agitated and replaced in the cassette.
