A mixing device for operating biological, chemical or biochemical materials used in an assay includes a mixing member formed with a plurality of chambers, each having a sealable port provided along an edge of the mixing member. The mixing device also includes one or more compartments that are movable along the edge of the mixing member between selected ones of the sealed chambers. This compartment is operable to receive materials from and transfer materials between the chambers. Selected ones of the chambers include associated processing elements, for example, including heating and cooling elements, magnetic elements, membranes and lateral flow devices. The mixing device is also pivotable, for example, to facilitate the application of gravity force in the transfer of materials between the chambers and one or more compartments. The mixing device may operate manually by hand-held unit. Also, this mixing device may operate automatically with at least one driving unit.

An apparatus includes a motor configured to move a platform on a predetermined orbit. The platform is connected to the motor, and the platform is configured to receive one or more vessels. Material included in each of the one or more vessels is mixed when the platform is moved on the predetermined orbit. The platform is sloped down, with respect to a horizontal axis, in a direction from any point along the predetermined orbit toward the center of the orbit.

A liquid medication dispensing machine capable of stirring a liquid medication contained in a liquid medication bottle in the machine with a simple structure is provided. The liquid medication dispensing machine supplying a liquid medication from a liquid medication bottle (23) containing the liquid medication to a prescription bottle includes a holder (78) holding a bottom (23B) of the liquid medication bottle (23), and a rotationally driving unit (61) generating rotary force and rotating the holder (78) and the liquid medication bottle (23) held by the holder (78) around a rotation axis (L3) extending along a center line (L2) of the liquid medication bottle (23).

Provided is a liquid medication dispensing machine that can shorten the time to supply a liquid medication to a prescription bottle. The liquid medication dispensing machine is a liquid medication dispensing machine supplying a liquid medication from a liquid medication bottle containing the liquid medication to a prescription bottle, including a liquid medication stirring unit that stirs the liquid medication in the liquid medication bottle, a bottle holding unit that holds a plurality of liquid medication bottles including a first bottle containing a liquid medication G and a second bottle containing a liquid medication B, and a control unit that controls operation of the liquid medication dispensing machine. The control unit operates the liquid medication stirring unit to stir liquid medication B while liquid medication G is supplied from the first bottle to the prescription bottle.

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.
