To investigate the flowability of a physiological fluid sample, an uptake passage ( 12 ) for the fluid sample ( 16 ), an actuator device ( 18 ) for the cyclic change in orientation of measuring particles ( 14 ) in the fluid sample ( 16 ), and a detector device ( 20, 22 ) for the preferably optical detection of the change in orientation of the measuring particles ( 14 ) are provided. In order to make reliable measurements possible with minimal instrument expense, it is proposed that the actuator device is formed by a pump unit ( 18 ) to produce a flow of the fluid sample ( 16 ) that travels back and forth along the uptake passage ( 12 ) and indicates the change in orientation of the measuring particles ( 14 ).
