Abstract
A rotor, adapted for rotation at high speeds, has symmetrically arranged radial channels for receiving tubular containers of material to be evaluated such for example as samples of blood. The outer end of each radially extending container filled with the sample to be evaluated is placed against a resilient abutment at the rim of the rotor, and the inner end of the container is placed in a receiving groove in a clamping member having limited axial movement relative to the axis of rotation of the rotor. The length of each sample container is such that it fits fairly snugly between the abutment and the clamping member when at a slight inclination to the plane of rotation of the rotor (that is, a plane perpendicular to the axis of rotation) when the clamping member is in a loading position. When the clamping member is then moved axially to its locking position, the sample container is swung through the plane of rotation to a slight angle on the opposite side thereof from the loading position, meanwhile compressing the resilient abutment at the outer end of the container by a toggle action. This holds the container firmly and safely for rotation at high speed, to separate the components…
