Abstract
A device is disclosed for measuring the coagulation time of a blood sample placed in contact with an appropriate reagent is described. A vibratory field inside an insulating receptacle is generated. Voltage variations between two electrodes disposed in the receptacle are measured which are indicative of a change in viscosity of the sample.
