Apparatus and method for measuring the coagulation characteristics of a test liquid

An apparatus and a method for measuring the coagulation characteristics of a test liquid, in particular of a blood sample, is provided. According to the present invention standardized geometrical dimensions of a cup and a respective pin are modified for receiving maximum elasticity signal per volume test liquid without resulting in irreversible inelastic effects. In particular, the test liquid gap between the cup and the pin is reduced, the diameter of the cup and the pin are increased and/or the geometry of test liquid accommodating portions (′) are optimized for increasing the ratio between signal amplitude and a needed amount of test liquid compared to standardized equipment.
