Cartridge For A Biological Sample

A cell separation system, wherein said system comprising:

• a. a first chamber adapted to contain at least a portion of a cell sample;
• at least a portion of said sample is characterized by at least one biological or chemical characteristic;
• said first chamber is bounded by a rim, such that said cell sample is kept below said rim;
• and,
• b. a second peripheral chamber;
• said second peripheral chamber is characterized by a circumferential depression around said first chamber;
• said second chamber is adapted to enable isolation of said at least a portion of said cell sample having the same biological or chemical characteristic, upon introduction of a separation-enabling agent.

A method for separating cells from a biological sample, said method comprising steps of:

• a. providing a cell separation system comprising:
• a first chamber;
• said first chamber is bounded by a rim;
• and a second peripheral chamber shallower, circumferential depression around said first chamber;
• b. depositing at least a portion of said biological sample into said first chamber of said cell separation system such that said cell sample is kept below said rim;
• at least a portion of said sample is characterized by at least one biological or chemical characteristic;
• c. introducing a separation-enabling agent into either said first chamber or said second chamber;
• thereby facilitating movement of said at a portion of said cell sample having the same biological or chemical characteristic into said second chamber of said cell separation system.
