Claim 0:
1. A centrifuge tube comprising:
a tube body, comprising an inner surface and an outer surface;
a sensor, provided at the inner surface of the tube body and comprising a first electrode group; and
a second electrode group, provided at the outer surface of the tube body and electrically connected with the first electrode group;
wherein:
the sensor comprises an electrochemical sensor, and the first electrode group comprises at least one reference electrode, at least one counter electrode, and at least one working electrode,
the second electrode group comprises at least one first lead-out electrode, at least one second lead-out electrode, and at least one third lead-out electrode,
the at least one first lead-out electrode, the at least one second lead-out electrode, and the at least one third lead-out electrode are provided at intervals at the outer surface of the tube body, and
the at least one first lead-out electrode is electrically connected with the at least one reference electrode in one-to-one correspondence, the at least one second lead-out electrode is electrically connected with the at least one working electrode in one-to-one correspondence, and the third lead-out electrode is electrically connected with the at least one counter electrode in one-to-one correspondence; and
wherein at least one selected from the group consisting of the at least one first lead-out electrode, the at least one second lead-out electrode, and the at least one third lead-out electrode is a ring-shaped electrode extending at least partially along a circumferential direction of the outer surface of the tube body.
