An apparatus ( 1 ) including two plates ( 3, 4 ) which can be rotated in relation to each other and between which the rheological properties of a test substance ( 6 ) disposed in an intervening area ( 5 ) can be determined. At least one of the plates ( 3 ) is provided with a light inlet ( 2 ) sealed by a body ( 8, 10 ) in order to carry out an optical measurement method, e.g., infrared spectroscopy, enabling other characteristics of the test substance to be determined simultaneously. The body ( 8, 10 ) is light permeable at least in the infrared spectrum, and on its side facing the intervening area ( 5 ), the body ( 8, 10 ) terminates in a flush contour relative to the to the plate ( 3 ) in which it is provided so that undesirable interactions which might affect the measurement of the rheological properties of the test substance ( 6 ) are reliably excluded. |
