ABSTRACT:
An apparatus for measuring the erythrosedimentation rate and carrying out other similar analyses through photometric reading, comprises one or more seats (9, 11) for receiving test tubes (P) inclined to a limited extent with respect to the vertical. Guide means (13) are provided for a skid (15) which is able to slide parallel to the test tube(s) (P) introduced into said seat(s) for the reading. On said skid (15), there are provided emitting and receiving members (19A, 19B) for a signal of optical type which goes through the or each test tube (P) during the reading scan. A motorization (3,5) moves said skid (15) along the test tube(s) for performing reading of the latter.
