The present disclosure relates to baffle assemblies, nozzles, and related systems and methods for handling solid discharges of centrifuge separators. In one implementation, a two-piece baffle assembly configured to be positioned around discharge nozzles of a centrifuge separator includes a first segment and a second segment configured to attach to the first segment. The first segment includes a first baffle, a second baffle, and a first discharge gap formed between the first baffle and the second baffle. The second segment includes a frame having an arcuate shape, a third baffle extending inwardly relative to the arcuate frame, a fourth baffle extending inwardly relative to the arcuate frame, and a second discharge gap formed between the third baffle and the fourth baffle.

A centrifugal field-flow fractionation device includes: a rotor having a rotation axis, the rotor being provided to be rotatable about the rotation axis; a cover covering the rotor; a protective member arranged inside the cover to over the rotor about the rotation axis; a shock-absorbing member arranged between the protective member and the cover; and a fixing part provided in a breakable manner to fix the protective member to the cover. The rotor is arranged such that the rotation axis orients in a horizontal direction. In a case where a part of the rotor disintegrates and is brought into contact with the protective member during the rotation of the rotor, the fixing part breaks to cause the protective member and the shock-absorbing member to move with the rotor while receiving the impact of the rotor to buffer the kinetic energy of the rotor.

In a centrifugal scroll screen apparatus there is provided a scroll assembly (20) driven by a scroll assembly drive shaft (25) and being connected to the scroll assembly by an axial adjuster comprising a shaft cam portion (92) and a scroll portion (96) each having a respective camming surface (94) whereby relative rotation of the scroll portion (96) and the shaft portion (92) axially adjusts the proximity of the vanes to a coaxial conical screening surface, and a locking ring (97) selectively operable to rotationally secure the scroll portion (96) and the shaft portion (92).

In a centrifugal screening apparatus wherein a housing (10, 11) mounts a screen assembly (12) and a scroll assembly (20) to be differentially rotated about the machine axis, there is provided an inlet assembly (30) having an inlet body (31) defining an annular inlet space (32) coaxial with and opening in to an open apical end of the screen assembly (12) and a material supply conduit (35) delivering material to be screened to the annular space (32) and being aligned in a tangent to the annular space to deliver material to the screen assembly (12) substantially in the direction of rotation of the screen assembly (12).

A centrifuge tube holding assembly includes a body having a front side, a back side, a top edge, a bottom edge, a first lateral edge and a second lateral edge. The top edge has a plurality of apertures extending downwardly therein and each of the apertures may be used for removably receiving an ultracentrifuge tube. The front wall has an opening therein for viewing an open space positioned below the top edge. A panel is positioned over the opening. The panel is transparent to allow viewing through the panel.

The panel has measurement indicia thereon configured to be positioned to be alignable with the ultracentrifuge tube.
