Centrifugal tube, single-tube centrifugal device, single-tube centrifugal reaction method, and continuous sample single-tube centrifugal system

A centrifugal tube, comprising:

• an outer tube, comprising a first accommodation space;
• a cover body, sleeved on the outer tube to seal the outer tube;
• and
• an inner tube, located in the first accommodation space, and comprising:
• an opening, for adding a reactant mixture into the inner tube;
• a coupling member, the inner tube is sleeved into the outer tube by the coupling member, the coupling member rendering the inner tube and the outer tube of the centrifugal tube to have a same axis, wherein a direction of a tube opening of the outer tube facing a bottom is a Z axis, and the axis is a connecting line between center positions of the inner tube and the outer tube on a plane perpendicular to the Z axis;
• a reaction chamber, in communication with the opening, for accommodating the reactant mixture added from the opening for reaction, a first narrow mouth further comprised between the reaction chamber and the opening;
• and
• a first liquid discharge port, communicating the reaction chamber with the first accommodation space, and symmetrically disposed in a direction perpendicular to the Z axis.
