Abstract: A fixed-angle rotor for centrifuges includes stiffening ribs on the lower side of its rotor body. Its rotational energy is comparatively low during operation even at high speeds, whereby safety is noticeably increased without the need for a reinforced armored vessel in the centrifuge that is equipped therewith. At the same time, the drive power required to drive the fixed-angle rotor remains low. The fixed-angle rotor also withstands extreme loads over a long period of time. In addition, the fixed-angle rotor can be manufactured cost-effectively, because no additional components are required; rather, the stiffening ribs can also be manufactured during the manufacture of the rotor body. Finally, very thin rotor shells can also be used, which improves the temperature control of the samples, because the fixed-angle rotor has very good structural stability, especially in the main load directions.

The solids catcher has a device for generating a fluid curtain against which the solids, issuing from the outlet openings for solid material, impact.

Abstract: Provided is a centrifugal field-flow fractionation device in which a liquid sample is less likely to leak from a channel and attachment and detachment work of a channel member is facilitated. By integrally forming an outer peripheral surface 162 and an inner peripheral surface 163 of a channel member 16, the channel member 16 is configured as one hollow member having a channel 161 formed inside. Thus, pressure resistance performance of the channel member 16 is improved, formation of a gap in the channel 161 can be prevented, and deterioration in sealing performance due to secular change is not generated. Accordingly, a liquid sample is less likely to leak from the channel 161. Further, since the channel member 16 can be handled as one member, attachment and detachment work of the channel member 16 is facilitated.
