Centrifuge rotor, holding crown and holding crown arrangement therefor, and centrifuge

A centrifuge rotor, comprising:

• a rotor body including a receptacle arranged centrally therein for receiving a drive head of a drive shaft of a centrifuge that is rotatable about an axis of rotation (R) and sample receptacles for accommodating a plurality of sample containers,
• wherein a holding crown is arranged on a top side (O) of the rotor body facing away from an insertion side (E) of the drive head, said holding crown having an annular base body which encloses a central opening and prongs extending upward away from the top side (O), and
• wherein the holding crown is arranged in such a way that the axis of rotation (R) runs through the central opening,
• wherein the sample containers have at least one tube which projects outward and opens into a sample receptacle space delimited by a container wall and the tubes of the sample containers define a tube assembly having branching points,
• wherein at least one tube of at least one sample container is passed between two adjacent prongs of the holding crown, and
• wherein tube sections of the tube assembly are fixed to the holding crown in a region of the branching points of the tube assembly.

A centrifuge rotor, comprising:

• a rotor body including a receptacle arranged centrally therein for receiving a drive head of a drive shaft of a centrifuge that is rotatable about an axis of rotation (R) and sample receptacles for accommodating a plurality of sample containers,
• wherein a holding crown is arranged on a top side (O) of the rotor body facing away from an insertion side (E) of the drive head, said holding crown having an annular base body which encloses a central opening and prongs extending upward away from the top side (O), and
• wherein the holding crown is arranged in such a way that the axis of rotation (R) runs through the central opening, and
• wherein a securing ring is arranged on the holding crown and has an annular base body enclosing a central opening and radially outwardly extending prong, wherein the prongs are arranged so that they lie in spaces between adjacent prongs of the holding crown.

A holding crown arrangement, comprising:

• a holding crown for use with a centrifuge rotor, comprising:
• an annular base body enclosing a central opening;
• and
• prongs emanating from the base body and extending upward,
• wherein the prongs are offset at least in a region of free ends of the prongs by a spacing (A) from an inner edge of the base body;
• and
• securing ring which is configured to be placed on the holding crown and which has an annular base body enclosing a central opening and prongs extending radially outwardly therefrom, wherein the prongs are arranged such that the prongs of the securing ring can come to rest in spaces between adjacent prongs of the holding crown.
