ABSTRACT:
Method of measuring the time of coagulation of samples of fluid products such as, for example, samples of blood plasma, wherein the dose of liquid substance to be analyzed is introduced into a small cup (1) the base (1a) of which is shaped to serve as a circular rolling path (1b) for a ball (2) disposed in the lower part of the cup which is actuated with a non-rotary circular movement be means of an eccentric (3-3a) causing a rotation of the ball in a circular path in the base of the cup. The gradual slowing and/or halting of the rotary movement of the ball caused by the thickening or coagulation of the sample of the medium or liquid substance contained in the cup, for example following the introduction of a reactant, is ascertainable visually or, preferably, by any suitable automatic detection system.
