A fixed angle centrifuge rotor includes a rotor body having a circumferential sidewall and a plurality of circumferentially spaced tubular cavities. Each tubular cavity has an open end and a closed end, and is configured to receive a sample container therein. The rotor further includes a pressure plate operatively coupled to the rotor body so that the pressure plate, in combination with the plurality of tubular cavities and the circumferential sidewall of the rotor body, define a hollow chamber within the rotor. The rotor further includes a plurality of elongated torque transfer members supported by the rotor body. Each of the plurality of torque transfer members has a first end located between a respective pair of adjacent tubular cavities, and extends radially inward in a direction toward a rotational axis of the rotor.

In a centrifuge having a rotor with a rotor body that holds a sample and that is rapidly rotated, an inclined surface that extends upward as it extends radially outward is formed on an upper-side outer peripheral portion of the rotor, in a region that is at a radially outward side and at an upper side of the outer edge of an opening. The inclined surface is a continuous ring-like inclined surface that has the same cross-sectional shape in the circumferential direction and is formed into a straight-line shape or a curved-line shape in cross-section along a rotation central axis. Although winds occur during high-speed rotation of the rotor, the winds are rectified by the inclined surface, and a component force for pressing the rotor body in a downward direction acts thereon.

A fixed angle centrifuge rotor includes a rotor body having a circumferential sidewall and a plurality of circumferentially spaced tubular cavities. An annular containment groove is disposed above and circumferentially surrounds the tubular cavities. Each tubular cavity has an open end and a closed end, and is configured to receive a sample container therein. The rotor further includes a pressure plate operatively coupled to the rotor body so that the pressure plate, in combination with the plurality of tubular cavities and the circumferential sidewall of the rotor body, define a hollow chamber within the rotor. The pressure plate includes circumferentially spaced upstanding tabs that are received in respective pockets located between adjacent tubular cavities. The rotor further includes a plurality of elongated torque transfer members supported by the rotor body. Each of the plurality of torque transfer members has a first end located between a respective pair of adjacent tubular cavities, and extends radially inward in a direction toward a rotational axis of the rotor.

The top of the centrifuge bin is provided with a hinge assembly, a bin lid assembly and a lid lock assembly, wherein the hinge assembly and the lid lock assembly are respectively arranged at two ends of the bin lid assembly; the cross-section of the bin lid assembly is equal to the cross-section of the centrifuge bin; and the hinge assembly comprises a lid opening linkage plate, a hinge shaft, a lug seat, pivots, a torsion spring, a torsion spring screw, a protective cover, shoulder bushings, bin-lid pivot damping gaskets, bin-lid bushings, compression nuts, anti-loosening gaskets and circlips.

A fixed angle centrifuge rotor is provided including a rotor body having an upper surface and a plurality of tubular cavities extending from the upper surface to respective bottom walls. A pressure plate is operatively coupled to the bottom walls of the tubular cavities and is configured to transfer torque to the bottom walls. The pressure plate is configured to be directly coupled to a rotor hub and to receive torque directly from the rotor hub.

An automated template bead preparation system is provided and includes a membrane-based emulsion generation subsystems, a thermal 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 thermal subsystem, in automated fashion. The thermal subsystem can treat an inverse emulsion passed therethrough. 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 centrifuge having a rotor attachment for preparing a small-format blood collection tube after blood collection for handling and analysis. The rotor attachment may include two or more small-container holding orifices designed to hold each container in a plane that is normal (or near-normal) to an axis of rotation during centrifuging. That is, the angle at which each small-format container is held during a centrifugation procedure is low (e.g., zero or near-zero). Having a rotor attachment that imparts a small angle or near-zero angle during centrifugation results is solutions being separated in layers that are aligned normal to a vertical axis of the small-format container. This separation into layers in the small-format container is more robust during handling and transport as a mid-level gel exhibits strong cohesion to the inner walls of the small-format containers, thereby maintaining separation between red blood cells as collected and a resident serum.

A valve bridge portion, in which four valves A to D are connected in a bridge shape, is interposed between sample lines to a rotor of a continuous centrifuge. A microcomputer is able to open and close the valves A to D independently and is capable of switching between top feed and bottom feed to the sample line. When sample supply is started, switching between the top feed and the bottom feed is performed multiple times, and in the middle of switching and sending a sample liquid, the microcomputer executes an operation of temporarily increasing a liquid pressure multiple times by temporarily closing an outlet valve (C or D) and then immediately opening the valve. As a result of repeating the operation of switching between the said sample feed directions and temporarily increasing the liquid pressure, air that accumulates inside the rotor can be effectively discharged.
