Abstract
Multi-component separation devices configured to separate components of a liquid sample by centrifugation are provided. Aspects of the separation devices include a container having a distal end and a proximal end and a buoy configured to be displaced along a longitudinal axis within the container where the buoy includes one or more sealed chambers. Also provided are methods of using the subject devices to separate components of a multi-component liquid sample such as whole blood, bone marrow aspirate or stromal vascular fraction as well as systems suitable for practicing the subject methods.
Claims21
A device for separating components of a multi-component liquid, the device comprising:
- a container comprising a distal end and a proximal end;
- and
- a buoy configured to be displaced along a longitudinal axis within the container, wherein the buoy comprises one or more sealed chambers.
A method comprising:
- introducing a biological sample into a device comprising:
- a container comprising a distal end and a proximal end;
- and
- a buoy configured to be displaced along a longitudinal axis within the container, wherein the buoy comprises one or more sealed chambers;
- subjecting the biological sample to a force of centrifugation to produce two or more fractions in the biological sample;
- collecting one or more fractions or portions of fractions of the biological sample.
A system comprising:
- a device for separating components of a multi-component liquid comprising:
- a container comprising a distal end and a proximal end, wherein the container comprises a cap positioned at the proximal end comprising an inlet into the cavity of the container;
- and
- a buoy configured to be displaced along a longitudinal axis within the container, wherein the buoy comprises one or more sealed chambers;
- and
- a) a support for positioning the container at an angle with respect to an axis orthogonal to the ground;
- or
- b) a centrifuge.
