In order to prevent air from being sucked into the separation chamber (12) of a counter-current type of centrifugal separator through the liquid outlet (24) thereof during the normal operation the separator a liquid trap in form of a well (28) is provided in the bottom of the separator housing (10). An outlet conduit (32) opens into the lower part of the well (28), wherein the well (28), at least in its upper part, has a substantially larger cross-sectional area than that of the outlet conduit (32).

A modular automatic analyzer using a circular type cartridge enabling centrifugation according to an exemplary embodiment of the present invention includes: a main body frame; an X-axis conveying unit which reciprocally moves in an X-axis direction with respect to the main body frame; a circular type cartridge accommodating housing which is installed with respect to the X-axis conveying unit so as to be reciprocally movable in the X-axis direction by the X-axis conveying unit, a single rotation drive unit which is installed in the circular type cartridge accommodating housing and is rotated step by step at a predetermined interval or rotated at a high speed for centrifugation, a circular type cartridge which is installed at an upper surface of the circular type cartridge accommodating housing so as to be rotatably connected to the rotation drive unit and has wells disposed to be spaced apart from each other at predetermined intervals in a circumferential direction of a disc-shaped main body, a tip lifting unit which picks up and moves a tip upward and downward, a measurement unit which measures a reaction in the well, a Z-axis drive unit which is provided with the tip lifting unit and the measurement unit and reciprocally operates in a Z-axis direction with respect to the main body frame, and a control unit C which controls an automatic immunity analyzer.

An automated on-touch template bead preparation system is provided and includes a membrane-based emulsion generation subsystems, an emulsion PCR (ePCR) thermocycling plate and subsystem, and a continuous centrifugation emulsion breaking and templated bead collection subsystem. The emulsion generation subsystem provides uniformity in the preparation of an inverse emulsion and may be used to create large or small volume inverse emulsions rapidly and reproducibly. An emulsion-generating device is provided that can supply a continuous stream of an inverse emulsion to a thermocycling subsystem, in automated fashion. The ePCR subsystem can continuously thermocycle an inverse emulsion passed therethrough and includes static temperature zones and a consumable thermocycling plate. The continuous centrifugation subsystem can continuously break a thermally cycled inverse emulsion and collect template beads formed in the aqueous microreactor droplets of the inverse emulsion.

A cover for a centrifugal filter, in which when water separated from oil is discharged through outlets provided in covers, can reduce the amount of oil leaking out with mixed gas and water. The cover constitutes the centrifugal filter by covering a rotor that rotates so as to filter impurities contained in oil by using a centrifugal force. The rotor is provided with at least one nozzle through which filtered oil is jetted. The cover includes: an inner cover configured to cover the rotor and including a first outlet and a first inlet; an outer cover provided outside the inner cover; and an oil leak prevention member provided in the first outlet.

A filter for an internal combustion engine includes an oil filter and a separator. The oil filter has a rotor that rotates about an axis in response to oil that is discharged from the rotor. The separator has a spindle that is detachably coupled to the rotor. A plurality of discs are mounted to the spindle, which is rotated about the axis by the rotation of the filter. The rotate of the spindle rotates the discs, which separates oil from gasses introduced into the separator.

A centrifuge includes light sources to provide different illumination states depending on the status of the centrifuge to communicate the status of the centrifuge. The light sources, when activated, project light in the centrifuge chamber and through the centrifuge lid. The light sources are preferably light-emitting diodes. The illumination state is visible up to at least a distance from the centrifuge at which no other visual information on the centrifuge is available. The illumination states allow staff to visually identify the status of a centrifuge from a distance and may reduce turnaround times by enabling staff to identify a completed centrifuge cycle more quickly, reduce staff time wasted checking on the status of a centrifuge, and reduce turnaround time wasted as a result of specimens sitting in a centrifuge after the centrifuge cycle has completed. Methods of communicating the status of a centrifuge are also disclosed.
