Read-off device for medical samples

Claim 1

A centrifuge device for centrifuging medical samples to separate the samples into visually distinct components and for measuring the proportions of such components without removing the centrifuged samples from the centrifuge, said centrifuge device comprising (a) a centrifuge rotor rotatable about an axis, (b) means for clamping on said rotor a plurality of tubular containers each open at both ends and each adapted to be completely filled with a sample to be tested, and each arranged radially with respect to said axis, (c) each of said containers being of the same length and each being clamped, during rotation of said rotor, in a definite predetermined location on said rotor, (d) a reading scale marked on said rotor alongside the clamped location of each of said containers, (e) each reading scale being graduated in percentage graduations from 0 to 100, (f) the zero graduation of each scale being precisely at one end of its associated container and the 100 graduation of the scale being precisely at the opposite end of its associated container when the container is in clamped position on the rotor, (g) a housing surrounding said rotor and said containers thereon, and (h) optical magnifying means connected to said housing to facilitate reading the point along said scale associated with one of said containers at which a junction line between two components of the contents of said one of said containers is observed.
