    Abstract: A filter for a centrifuge tube including a pressure filter for separating a mixture under centrifugal force. The filter tube is adapted to fit within the upper portion of a standard plastic centrifuge tube. The filter tube has a pressure filter at its lower end and an opening at its upper end adapted to be sealed by a cap extending from the centrifuge tube to hold the filter tube securely in position within the centrifuge tube. The filter tube is filled with a mixture of permeable and non-permeable materials and when the composite centrifuge tube and filter tube is spun in the centrifuge, the centrifugal force causes the permeable materials to flow through the filter and collect in the bottom of the centrifuge tube while the non-permeable materials are retained in the filter tube.

    Abstract: A filter apparatus comprises a filter element inside a stationary housing. In one embodiment, an inlet manifold extends helically along the outside of the housing. A director blade within the housing causes the unfiltered liquid from the inlet manifold to strike the filter element tangentially in a direction opposing filter element rotation. The filtered liquid passing through the filter element is withdrawn from the interior of the filter element. A stationary vane or deflector inside the filter element parallels the director blade and inlet manifold and forces some filtered liquid radially outwardly through the filter element, at the point where the inward flow impinges on the filter element, for loosening contaminant from the outside of the filter element. Adjacent this point a gathering blade extends inward from the housing toward the filter element in parallelism with the inlet manifold to intercept the rotational flow and loosened contaminant adjacent the outside of the filter element and direct same radially outwardly into a drain chamber, creating a vortex flow therein. The drain chamber is oriented and contoured to cause vortex flow downwardly to direct contaminant particles to a drain. In another embodiment, the helical inlet manifold is omitted and the filter liquid is merely introduced into the housing externally of the filter element by a suitable conduit. In a further embodiment, the guide vane or deflector inside the filter element is omitted and a backwash liquid supply tube is provided within the filter element opposite the gathering blade and has outlet openings facing the filter element wall for direction of backwash liquid flow outwardly through the filter element to force contaminant particles from the exterior of the filter element.

    Abstract: The disclosure relates to a filter in use for centrifugal separator including a filter film between a sample chamber and a filtrate chamber. The filter film is inclined or parallel to an axis of the filter. Accordingly, when the filter is utilized for either the angle rotor type and swing rotor type of centrifugal separators, the filter is positioned, during operation, so as to be inclined or parallel to the direction of the centrifugal force so that the residue contained in the liquid sample in the sample chamber moves radially outwardly with respect to the axis of the rotors so as to slide on the filter film or so as to leave from the filter film. Thus, the filter film will not easily result in clogging with the residue so that the high filtration speed can be maintained for a long period of time.

    Abstract translation: 本公开涉及一种用于离心分离器的过滤器，其包括在样品室和滤液室之间的过滤膜。 过滤膜与过滤器的轴线倾斜或平行。 因此，当过滤器用于角式转子式和回转式离心分离器时，过滤器在操作过程中被定位成倾斜或平行于离心力的方向，使得残留物 样品室中的液体样品相对于转子的轴线径向向外移动，以便在过滤膜上滑动或者从过滤膜离开。 因此，过滤膜不容易导致残留物的堵塞，从而可以长时间保持高的过滤速度。

    Abstract: An impregnated porous disc made of an inert material with voids adapted for insertion into a collection tube containing clotted blood which disc upon centrifugation of the tube will allow separation of fibrin and cellular material from the serum by centrifugal force during its controlled descent through the serum and will stop when it hits the serum-clot interface to isolate the serum from the clot.

    Abstract: A backwashable filter comprises (a) an outer case, (b) a rotatable, permeable filter drum, (c) a fibrous filter element supported on the surface of the drum, (d) one or more stationary backwash arms, (e) a feed inlet leading to one side of the filter drum and (f) a filter outlet emerging from the other side of the drum. The backwash arms are in close contact with the filter element. The tendency of the feedstock to bypass the filter and enter the backwash arms is thereby reduced.
