Cartridge for a biological sample

A device for assaying at least one biological sample, comprising:

• a. at least one removable cartridge, adapted to facilitate one or more assays of said at least one biological sample, said cartridge comprising a body, said body comprises:
• i. at least one compartment adapted to contain said at least one biological sample;
• ii. one or more assay locations, in which at least one of said assays of said at least one biological sample is provided;
• and
• b. at least one actuator adapted to interface with said cartridge to enable transportation of said at least one biological sample towards at least one of said assay locations,
• wherein said compartment comprises:
• i. a central chamber shaped as an open dimple in said body, said central chamber is bounded by a first rim defining a perimeter of said central chamber;
• and
• ii. a peripheral chamber shaped as an open circumferential depression extending entirely around said central chamber, said peripheral chamber is shallower than said central chamber and is bounded by said first rim and a second outer rim which extends higher than said first rim, such that upon introduction of a separation-enabling fluid, said portion of said at least one biological sample can be separated according to its relative motility by transfer from one of said central chamber and said second peripheral chamber to the other over said first rim at any point along said perimeter of said central chamber.
