Abstract
Embodiments relate to systems, chambers, and methods for processing particles by washing, concentrating, and/or treating the particles. Some embodiments provide for the processing of cells that may be in a liquid medium (e.g., a liquid in which the cells were grown) and are processed by being washed and concentrated for later use in research or other therapies.
Claims21
A chamber for separating particles from a liquid, the chamber comprising:
- a first side wall defining a first volume, wherein the first volume comprises a first cross-sectional area and a second cross-sectional area, the second cross-sectional area being smaller than the first cross-sectional area;
- a second side wall defining a second volume located above the first volume;
- a first port in fluid communication with the first volume, wherein the first port is located in the first side wall;
- a first wall adjacent the first port, the first wall, said first wall being curved and preventing flow of particles in liquid into the second volume, wherein the first wall at least partially defines a channel for flow of particles away from the second volume;
- a second port in fluid communication with the first volume, wherein the second port is located below the first port;
- and
- a third port in fluid communication with the second volume, wherein the third port is located above the second port.
