A resin dispensing apparatus includes a supply unit including a syringe having an internal space configured to hold a phosphor-containing resin. An agitator is disposed in the internal space. The supply unit is configured to rotate at least one of the syringe and the agitator to prevent settling of phosphor contained in the phosphor-containing resin. A discharge unit includes a cylinder having a discharge nozzle through which the phosphor-containing resin, received through a connecting pipe connected to the syringe, is discharged. A piston provides pressure to discharge the phosphor-containing resin through the discharge nozzle inside the cylinder.

in which R.sub.6 and R.sub.7 may be the same or different and each independently represents a C1-4 linear or branched alkylene group, and m represents an integer of 1-5; R.sub.3 and R.sub.4 may be the same or different and each independently represent a hydrogen atom, substituted or unsubstituted C1-4 linear or branched alkyl group; X.sup. represents a counter ion; and n represents 0-30.

The invention discloses an analytical sample preparation device and an analytical sample preparation method, which comprises a base (1), an elastic connection body (5), a group of a synchronous unidirectional bearing inner ring (41) and a synchronous unidirectional bearing outer ring (42), a group of an eccentric unidirectional bearing inner ring (61) and an eccentric unidirectional bearing outer ring (62), and a synchronous fixed ring (2) and a motor (31) on the base (1). The eccentric unidirectional bearing inner ring (61) is connected with an eccentric shaft (32) extending from a motor (31). The eccentric unidirectional bearing outer ring (62) is fixed to an eccentric shaft sleeve (9). The eccentric shaft sleeve (9), the eccentric shaft (32), the eccentric unidirectional bearing inner ring (61), and the eccentric unidirectional bearing outer ring (62) have their center of mass disposed on a line extending from the center line of the motor (31). The eccentric unidirectional bearing inner ring (61) and the eccentric unidirectional bearing outer ring (62) can only rotate in direction A, while the synchronous unidirectional bearing outer ring (41) and the synchronous unidirectional bearing outer ring (42) can only rotate in a direction opposite to direction A.

Inside a driven cylindrical housing 23 that is a cylindrical rotation member 13, a liquid to be mixed 4 is caused to become an inner circulation current f by extruded plate portions 24A-24D. Discharge ports 22A-22D formed in the cylindrical housing 21 discharge a portion of the inner circulation current f outward as outer discharge current d1-d4 by centrifugal force. At the same time, the outer portion of the liquid to be mixed 4 is sucked into suction ports 23, 30 as suction current e1-e3, h1-h4, thus mixing the liquid to be mixed 4 in the mixing tank 3.

Device for shaking, within a rigid container, a powder and liquid, for conducting a test on the shaken content, includes: a frame; a first plate assembled thereto; a second plate assembled indirectly to the frame, arranged close to the first plate and movable relative to the frame and first plate; and a drive unit for moving the second plate relative to the frame and first plate. The container is carried by the second plate and is movably mounted relative thereto; the first plate includes a stop fixedly mounted on the first plate; and the second plate is moved relative to the first plate by the drive unit, in an alternating and periodic translational and/or rotational motion between a proximal position and a distal position, to move the container relative to the second plate and cause a series of impacts between the container and the stop to achieve a non-periodic shaking.

An automated sample mixing and centrifuging apparatus capable of mixing the contents of one or more centrifuge sample tubes and then centrifuging the sample tubes in the same apparatus is disclosed herein. The apparatus comprises an electric slip ring, one or more mixing actuators, a device motor, and a rotor.

A method of stirring a test substance-containing solution injected into an analysis chip, wherein said analysis chip includes a recess to which said test substance-containing solution is injected; and a selective binding substance, which selectively binds to said test substance, is immobilized on the entirety or a part of the bottom surface of said recess, said method including injecting said test substance-containing solution to the space in said recess of said analysis chip such that said space is partially left unfilled; and rotating said analysis chip to which said test substance-containing solution is injected applying a centrifugal acceleration of not less than 1g.

A liquid handling device having an axis of rotation about which the device can be rotated to drive liquid flow in the device. The device includes an upstream chamber comprising an outlet, a downstream chamber including a proximal portion radially inwards of a distal portion and including a first port disposed in the distal portion and a first conduit which connects the outlet of the upstream chamber to the first port of the downstream chamber. The first conduit extends radially inwards to a crest and radially outwards from the crest to the first port of the downstream chamber. A distance between the axis of rotation and the crest is greater than or equal to a distance between the axis of rotation and the outlet of the upstream chamber.
