Abstract: A closure for attachment to a sample container for use in a centrifuge includes a top wall, an annular skirt wall depending from the top wall and defining a maximum outer diameter, and a handle extending from the top wall and including a central boss and at least two finger grips extending radially outward from the central boss. A respective free terminal end of each of the finger grips is located so as not to extend beyond the maximum outer diameter.

Abstract: 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.

Abstract: A centrifuge rotor is provided having a rotor core that defines a rotational axis of the rotor. A plurality of bucket supports is arranged about the axis of rotation. The rotor includes first and second straps that respectively wrap around two diametrically-opposed ones of the bucket supports for restricting outward movement of the two bucket supports relative to the rotor core. The first and second straps intersect one another at a location through the axis of rotation of the rotor.

Abstract: A centrifuge rotor is provided. The rotor includes a compression-molded rotor body that includes a central hub defining an axis of rotation of the rotor body, and a plurality of bays, each configured to receive a bucket therein. A plurality of load transferring members are integrally molded with the rotor body and each include a bucket support for supporting a bucket, with the bucket support permitting pivoting movement of the bucket during centrifugation of the rotor body about the axis of rotation. A reinforcement layer extends circumferentially and/or helically around an exterior of the rotor body.

Each of the cavities has an open end and a closed end and is configured to receive a sample container therein. A pressure plate is operatively coupled to the plurality of tubular cavities so that the pressure plate, in combination with the plurality of tubular cavities, defines an enclosed hollow chamber between each adjacent pair of the plurality of tubular cavities. Each of the plurality of tubular cavities has a sidewall facing an interior of the rotor body and a bottom wall at the closed end.

Abstract: A centrifuge rotor includes a rotor body having a central hub and first and second bucket receiving spaces defined on diametrically opposed sides of the rotor body. A first pair of bucket supports is supported by the rotor body for pivotally supporting a swing bucket in the first bucket receiving space, and a second pair of bucket supports is supported by the rotor body for pivotally supporting a swing bucket in the second bucket receiving space. The rotor further includes reinforcing material wound around oppositely disposed ones of the first and second pairs of bucket supports.

Abstract: A centrifuge rotor includes a rotor body having first and second axial ends and a circumferential sidewall extending therebetween. The rotor body has a plurality of wells for receiving sample containers to be processed in the rotor. The rotor further includes an elongate reinforcement extending around the circumferential sidewall of the rotor body along a helical path. At least two portions of the elongate reinforcement interlock at one or more specific points on the surface of the rotor.

Abstract: A bucket is provided for use with a centrifuge rotor. The bucket includes a bucket body that has a side wall and a bottom wall. A pair of projections extend from the side wall on opposing sides of the bucket body and are configured for engagement with the centrifuge rotor. The bucket also includes reinforcing material coupled to the projections for restricting movement of the bucket body relative to the projections during centrifugation on the centrifuge rotor. The projections may include bushings that extend outwardly from the side wall for engaging corresponding pins on the centrifuge rotor. The projection may alternatively or additionally include pins for engaging corresponding journals on the centrifuge rotor. The bucket body may include a pair of diametrically opposed apertures, with each of the projections extending through one of the apertures.
