A liquid analyzing device includes a carrier, a rotating plate, and a driving unit. The rotating plate rotatably connected with a pivot portion of the carrier contains a test liquid. The rotating plate or the driving unit has a stopping portion. When the driving unit drives the rotating plate to rotate so the stopping portion moves to a first position and interferes with the carrier, the driving unit applies driving force to the pivot portion of the carrier along a first rotation direction through the rotating plate. When the carrier rotates along the first rotation direction and the driving unit applies driving force to the rotating plate along a second rotation direction opposite to the first rotation direction, the rotating plate rotates relative to the carrier, the stopping portion moves to a second position and interferes with the carrier, and the driving unit applies driving force to the pivot portion of the carrier along the second rotation direction through the rotating plate.

The present disclosure relates to a rotatable tube rack holder for a tube rack rotator device, comprising: one or more plate(s) extending radially from an axis of rotation; one or more compartment(s) for tightly holding one or more tube rack(s) configured to hold a plurality of tubes, said compartment(s) is/are attached to at least one side of said plate(s); and one locking mechanism for each of said compartment and configured such that when said tube rack(s) holding a plurality of said tubes is/are placed inside said compartment, said tubes are restricted from moving in a direction perpendicular to said plate.

A centrifugal mixing device can include a shaft assembly that is operably coupled to a motor such that the motor rotates the shaft assembly about a first axis. The devices can further include a turret that is rotatably coupled to the shaft assembly such that the turret rotates about the first axis relative to the shaft assembly. The turret can include a first support, a first canister rotatably coupled to the first support such that the first canister rotates about a second axis, and a second canister rotatably coupled to the first support such that the second canister rotates about a third axis. The turret is configured to rotate about the first axis in a first rotational direction and each of the first and second canisters is configured to rotate about the second and third axes, respectively, in a second rotational direction that is opposite the first rotational direction.

The present invention provides a device and a method for automated liquid exchange in a horizontally rotating container that may be applied in automated sample treatment by using chemical solutions, in sequential order. Such applications include biomolecule staining on solid support or fixed samples such as western blot or tissue slice processing. Such sequential chemical reactions are usually performed on flat surfaces. Alternatively, these reactions can be completed with much less volume of reagents in horizontally rotating containers. Yet, it is difficult to automate these processes in rotating containers since the required tubing would twist due to the continuous rotation of the container. The present invention solves the problem of twisting of tubing by leading them through a stationary tubing carrier that passes through the rotating container. Hence, the rotation of the tubing, and therefore twisting, is avoided, thus enabling automated liquid exchange of various chemical solutions in rotating containers.
