An apparatus, method, and sample vessel for recombining a sample fluid. The sample fluid is received in a sample vessel. Sample parameters are recreated in the sample vessel. The sample fluid is agitated within the sample vessel. Optical measurements of the sample fluid are performed within the sample vessel utilizing one or more optical sensors. A determination is made whether recombination is complete in response to the optical measurements of the sample fluid performed by the one or more optical sensors.

A flow disrupter in a tube chamber of a tube assembly for homogenizing sample materials includes a flow-disrupting body that extends generally transversely into the tube chamber and divides the tube chamber into two sub-chambers. The flow-disrupting body includes at least one narrowed flow passageway through which the sample flows back and forth in both axially reciprocating directions as the tube assembly is vigorously shaken at high speeds faster and more reliably than what can be accomplished by hand shaking. And the flow-disrupting body includes at least two flow-interrupting surfaces facing generally in opposite axial directions and against which the sample impacts in each respective axially reciprocating direction as the tube assembly is vigorously shaken. In this way, the vigorous high-speed shaking of the tube assembly including the flow disrupter results in significant particle-size reduction of the sample by mechanical shear, fluid shear, cavitation, and/or pressure differentials.

The present invention recognizes the need for an apparatus and method for creating carbonated beverages having a customizable carbonation level. The invention uses a CPU to control an inlet valve which connects a tank of pressurized carbon dioxide to a vessel containing the beverage to be carbonized. The tube connecting the tank of pressurized carbon dioxide to the vessel contains an orifice for reducing the carbon dioxide's flow rate, thereby increasing control over the amount of carbon dioxide introduced to the vessel. A motor agitates the vessel, causing the carbon dioxide to become absorbed in the beverage. Then, an outlet valve causes excess pressure to drain from the vessel. An outlet orifice causes the pressure to release gradually, thus preventing the beverage from foaming.

[Object] The invention provides an analysis chip by which the efficiency of reaction with a selective binding substance is promoted by using particles having a large size to promote the efficiency of stirring of the test substance solution without damaging the portion of the carrier on which the selective binding substance is immobilized, by the moving particles when stirring the test substance solution with the particles. [Means of Solution] An analysis chip including a carrier having a surface on which a selective binding substance(s) is(are) immobilized; a vessel holding a solution containing a test substance(s) which react(s) with the selective binding substance(s); and particles for stirring the solution, the particles being sealed within a space formed between the carrier and the vessel; wherein a separator which allows passage therethrough of the solution containing the test substance(s) but does not allow passage therethrough of the particles is arranged in the space so as to separate the surface of the carrier on which the selective binding substance(s) is(are) immobilized and the particles; a method of analysis using the analysis chip; and a method of stirring a solution using the analysis chip.
