Abstract
The present invention relates to the field of photometric analysis, particularly to photometric analysis apparatuses which use disk-shaped rotors, in which the rotors are loaded automatically.
Claims22
A method of operating a photometric analysis apparatus comprising the steps of:
- a) providing one or more rotors, each rotor comprising:
- a disc comprising a plurality of cuvettes, and at least a first notch positioned on the periphery of the disc, the first notch being V-shaped, wherein one side of the V-shape is more inclined than the other side of the V-shape, thereby providing a lead-in for a pincer to move the rotor from one position to another position;
- b) loading the one or more rotors into the photometric analysis apparatus;
- and
- c) optically analyzing the contents of the plurality of cuvettes.
