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.

Method of operating a photometric analysis apparatus

The present invention relates to photometric analysis apparatus of the type which uses disk-shaped rotors, in which the rotors are loaded automatically. In particular, the present invention relates to photometric analysis apparatus of the type which uses disk-shaped rotors, characterized in that it has a device for loading the rotors ( ) onto analysis apparatus ( ) automatically, the device comprising a hopper ( ) for supplying the rotors, the hopper ( ) comprising asymmetric notches for locating the rotors ( ) positively in the hopper.

Rotor for presenting samples in photometric analysis

A coupling arrangement between a hub and multi-cuvette rotor in analytical photometers, wherein the hub has a projection the section of which has a non-revolving profile and to such end comprises at least one rectilinear segment, the rotor designed for said hub featuring centrally a seating adapted to receive said projection on which hub, peripherally to said projection and distanced from the rectilinear-segment portion, there are arranged radially yieldable elastic elements provided with a portion which projects from said profile so that it elastically associates with the matching seating in the rotor.
