The composite liquid may include, in embodiments, a cellular containing liquid, such as whole blood or components of whole blood. In one specific embodiment, the composite liquid is a buffy coat.
Claims20
A separation chamber comprising:
- a sidewall defining a chamber volume;
- a flexible membrane located in the chamber volume and defining a membrane volume;
- an inlet in fluid communication with the membrane volume;
- and
- an outlet in fluid communication with the membrane volume.
The separation chamber of claim 6, wherein the cap comprises a first portion and a second portion at least one of the first portion or the second portion comprising a channel.
A disposable blood separation set comprising:
- a blood processing vessel adapted to be mounted on a centrifuge rotor;
- and
- a flexible membrane defining a membrane volume, wherein an inlet and an outlet are in fluid communication with the membrane volume.
A method of separating cellular components, the method comprising:
- transferring a liquid comprising whole blood into a blood processing vessel;
- separating the liquid comprising whole blood into at least a first component comprising cells and a second component;
- transferring the first component into a membrane volume defined by a flexible membrane;
- separating cells from the first component in the membrane volume;
- and
- removing the cells from the membrane volume.
