An apparatus for and method of enabling enhanced, selective agitation of liquid containing a solid-phase reagent. The apparatus includes at least one liquid-bearing container, a circular tray, and a motor. The liquid-bearing container(s) includes at least one internal baffle that imparts turbulent agitation to the liquid when flowing from one end of the container to an opposite end. The circular tray is adapted for selective rotation about a vertical axis of rotation. The rotary circular tray assembly includes container-receiving stations that selectively retain a respective liquid-bearing container in an inclined or pitched orientation with respect to a horizontal plane. The motor creates centrifugal force, which causes liquid in the container(s) to travel from the first end of the container to the second end of the container via the internal baffle(s), agitating the liquid and the solid-phase portions of the reagent. When gravitational force exceeds the centrifugal force, liquid in the container(s) travels from the second end of the container to the first end of the container via the internal baffle(s), again agitating the liquid and the solid-phase portions of the reagent.

A chip for sample analysis is provided. The chip for sample analysis according to an embodiment of the present application includes a sample storage unit, a capture path configured to capture an analyte contained in a sample and communicating with the sample storage unit, a washing solution storage unit communicating with the capture path and a delay unit included between the capture path and the washing solution storage unit such that a washing solution flowing from the washing solution storage unit to the capture path passes through. When the chip is rotated for sample analysis, the delay unit may be configured to delay the passage of the washing solution introduced from the washing solution storage unit such that the washing solution reaches the capture path later than the sample.

In addition, a cartridge which is mounted on the chip for sample analysis and includes at least one inlet which is inserted into at least one of a sample storage unit, a first eluent storage unit, a second eluent storage unit and a washing solution storage unit of the chip for sample analysis to inject a corresponding solution, is provided.
