Abstract
Test tube for biological analyses, and in particular for blood tests such as erythrocyte sedimentation rate, provided with a device making it possible to perform a photometric inspection of the test tube with a relative movement between the optical system and the test tube (1), the latter being between the emitter (E) and the receiver (R) of said system; the test tube possesses--externally on the base--a device in the form of an optical prism (5) that induces a sudden change in the direction of the light beam emitted by the emitter so that it briefly is unable to reach the receiver.
