Abstract
A centrifuge system designed to receive a rotor having variable volumes adapted for collecting and centrifuging biological fluids. The centrifuge system encompasses a chuck that slides along the axis of rotation inside a rotating bucket. Thereby stretching or contracting the volume of the rotor.
Claims8
A centrifuge system having means for holding and spinning a rotor with variable volume around the axis of rotation so as to separate biological fluids into a denser component, a lighter component, and an intermediate density component, the system comprising;
- a bucket fixated to the rotating shaft and spins therewith,
- a chuck spinning with the bucket and permitted to slide inside along the axis of rotation,
- means to slide the chuck inside the bucket, whereas these means are embedded in the rotating assembly and spin therewith, and
- a motor for spinning the rotating assembly.
A centrifuge system having means for holding and spinning a rotor with variable volume around the axis of rotation so as to separate biological fluids into a denser component, a lighter component, and an intermediate density component, the system comprising;
- a chuck fixated to the rotating shaft and spins therewith, said chuck having vacuum means or mechanical means activated by centrifugal forces or pressurized fluids to firmly hold the rotor's base,
- a bucket spinning with the rotating shaft and permitted to slide vertically relative to the chuck along the axis of rotation,
- a pneumatic piston embedded in the rotating assembly and spins therewith, used to vertically move the bucket along the axis of rotation, and
- a motor for spinning the rotating assembly.
