A rotor for a centrifugal analyzer comprising:
- a generally disc shaped member defining therein;
- a loading cell for a sample to be analyzed, said sample cell including an outlet,
- a loading cell for a reagent, said reagent cell including an outlet,
- a measuring chamber,
- a common transfer channel having an inlet and an outlet, a separate communicating passage between the outlet of each said loading cell and said transfer channel inlet each of which passages passes the fluid from the respective cell to said transfer channel inlet without passing through the other cell, the outlet of said transfer channel transferring both the sample and the reagent to the measuring chamber, and
- obstacle means in said transfer channel for mixing the sample and the reagent during the transfer.
