The present invention relates to a rotor for laboratory centrifuges, the rotor including a rotor housing that is open to the top and at least one recess for taking up centrifuge containers, with the recess being formed in the peripheral area of the rotor as a concentric, circumferential ring trough having an inner wall and an outer wall and with the ring trough being stiffened in a spoke-type manner in such a way using centrifuge containers that are distributed radially and over the circumference of the ring trough that the centrifuge containers support the inner wall and the outer wall rigidly against one another. Furthermore, an adapter for receiving a sample container and for use in such a rotor is suggested.
