A centrifugal separator includes a rotating body driving and sealing structure in which a hermetically sealed space is formed between a rotating body and an outer case by sealing the inside and outside using a noncontact seal during rotation of the rotating body, in an airtight manner. A rotation coupling unit is provided at the upper end of a centrifugal cylinder, and even when the centrifugal cylinder is deformed during use causing an internal fluid to leak through a fitting portion of a bottom member to the centrifugal cylinder, the fluid leaks in the hermetically sealed space so that the driving system or the like is not contaminated.

An apparatus for separating a mixture of insoluble liquids of different densities includes a stationary housing, and a rotatably mounted separator tank within the housing. The tank has an inlet adjacent the lower end of the tank, and an outlet adjacent the upper end of the tank. An outlet port plate located in an upper end of the rotatably mounted separator tank has a plurality of outlets spaced at different distances from the tank axis of rotation. One or more removable access plates are provided in a top wall of the stationary housing for providing access to removable plugs in the plurality of outlets in the outlet port plate.

Cell separation systems and methods of separating cells are disclosed. In an embodiment, a cell separation system is described that comprises a non-transitory storage device that executes a centrifugation program to separate cell volume from biologic material volume; a heating mechanism; a containment mechanism; and an assembly comprised of a single-walled centrifugation bowl. In an embodiment, methods of separating cells are disclosed whereby cells are separated by agitating a volume of biologic material and a volume digestion media to form a digested volume of biologic material; centrifuging the digested volume of biologic material; removing a portion of a resulting waste via at least one fluid outlet; isolating a different portion of the waste, and removing the concentrated cell volumes from the reservoir.

Provided is a lid stand that can accommodate a lid of a sealed rotating container of a centrifugal smearing device in a leaned state and so that liquid dripping can be prevented, without securing a wide space on a desk, and that can similarly lower a risk of touching a liquid specimen also for both right-handed and left-handed operators. A lid stand (1) of the present invention is a lid stand against which a lid (142) fitted in a sealed rotating container (134) of a centrifugal smearing device (130) and having a flange portion (151) protruding in a radial direction in a peripheral portion (142d) and a cylindrical scattering protective wall (160) protruding to a rear surface direction is placed by leaning, wherein: a center supporting member (10) having an upper supporting portion (12) supporting a center vicinity portion (142c) of the lid (142) on both one side and the other side is disposed at a center position; and a lateral side supporting member (20) having a lower supporting portion (22) supporting the peripheral portion (142d) of the lid (142) is disposed at positions on both sides being the one side and the other side with respect to the center supporting member (10).

This disclosure relates to an annular centrifugal extractor with Solid Separation Part to Separate Solid Particles Present in Solvent Extraction Fluid. In order to remove solid particles from the solution, a solid separation part/rotating bowl is attached to rotating bowl in such a way that solid particles settle inside the solid separation part. This solid separating centrifugal extractor contains two parts: (I) upper part which acts as a liquid-liquid separator to separate aqueous and organic solution used in solvent extraction operation and (II) bottom part which acts as a solid separator to separate solid particle present in solvent extraction liquids. The bottom rotating rotor is coupled with upper rotating rotor by threading arrangement. Both the rotating rotors are confined within a stationary cylinder. Dispersion with solid particles entering inside the rotating bowl is deflected towards the wall of the rotating cylinder by deflecting baffle by centrifugal sedimentation.

A portable centrifuge having a housing containing a rotational mechanism and a centrifugal container having a longitudinal axis. The rotational mechanism has a circuit including an electrical motor, a switch, and an internal electrical power source. The centrifugal container is operably connected to the rotational mechanism through the housing, and is rotatable about the longitudinal axis. The centrifuge is portable and is for single use.

A rotor bowl for use in a centrifugal concentrator for separating particulate material of higher specific gravity from a liquid slurry comprising a liquid and particulate material of different specific gravities, wherein the inner surface of the rotor bowl has an outwardly inclined migration surface and a capture zone above the migration surface, wherein the capture zone has a generally vertical annular wall located radially outwardly of the migration zone, and the generally vertical annular wall has a vibratory surface adapted to be selectively vibrated to thereby stratify particulate material or slurry located in contact with or adjacent to the vibratory surface within the capture zone to thereby permit the heavier concentrate to accumulate in the area closest to the wall of the capture zone. The vibratory surface may be the continuous inner liner of the capture zone, or separate vibrating surfaces may be provided on the surface of the inner liner in the capture zone.

The vibratory motion may be provided by one or more vibrators mounted radially outwardly of each vibratory surface. The rotor bowl may also comprise a plurality of springs mounted on the outer periphery of the vibrators and which are each biased to bear against the outer surface of a vibrator to offset centrifugal force so that each vibrator is kept in contact with the vibrating surface during rotation of the hollow bowl.
