A device comprising a rotating means enclosed in a housing and having a horizontally arranged rotating shaft. Containers for cassettes containing samples are mounted on the rotating shaft and are joined in the form of a vertically arranged ring. The device has a means for rotating the rotating shaft at a variable speed and vessels containing processing and infiltrating liquids, said vessels being arranged outside the housing and being connected thereto by pipes for feeding in and discharging said liquids. The device additionally contains a mechanism for orienting the containers for cassettes containing samples, which mechanism is arranged between the ring of containers and the wall of the device, has a separate means for transferring the containers for cassettes containing samples into a horizontal or inclined position and holds same in the horizontal or inclined position.

Some embodiments relate to a mixing device for fluid products contained in containers is described, comprising a plurality of cups configured to house the containers of the liquids to be mixed inside them and operated by means of a train of gears by motor means in so as to rotate simultaneously with a revolution motion around a vertical axis and with a rotation motion around an axis of the cups which is inclined by an angle with respect to the vertical axis, the mixing device also comprising a counterweight fixed to a support of the cups on the opposite side with respect to the vertical axis.

A mixer is provided for mixing a substance in a container. The mixer includes a motor; a frame configured to be controlled by the motor to rotate on an axis; a carrier disposed at a first end of the frame and configured to hold the container; a counterweight disposed at a second end of the frame opposite to the carrier, wherein the counterweight position relative to the axis is adjustable. The mixer may be a stand-alone unit, or it may be disposed in an apparatus for dispensing a cosmetic composition.

A rotating cup, both hands implement relatively forward and backward rotation to generate agitation effect, for mixing powdered material with liquid and stirring food material, such as egg liquid, especially suitable for the open air. The rotating cup comprises an inner cup, a first outer cup and a second outer cup which are coaxially superposed. A fixed axle penetrates through the center of circle of the first outer cup, and both ends of the fixed axle are fixed to the centers of circle of inner cup and the second outer cup, so that the second outer cup and inner cup are interlocked, and the first outer cup can idle. The rotating cup can be equipped with a transmission structure and a stirring rod simultaneously or respectively. On the one hand to provide unidirectional rotation effect and acceleration effect for quick mixing, on the other hand to provide a better agitation effect.

The invention relates to a sample processing system and method for processing biological samples, comprising a sample processing device having: a receiving plate, which is arranged substantially horizontally in a plane; a first and second working arm, which can move relative to the receiving plate and extend substantially parallel to each other in a second direction (Y) over the receiving plate; at least one pipetting device mounted on the first working arm, which is movable in the second direction (Y) and in a third direction (Z) orthogonal in relation to the first and second direction (X, Y); at least one gripping device, mounted on the second working arm, with grippers that can be rotated around a gripper axis of rotation (GA) parallel to the third direction (Z); and a control device for controlling the pipetting device and the gripping device.

A filtering and ventilating mechanism is driven by motors. The filtering mechanism rotates and presses downwards so its pressing surface is against a sample container. A ventilation needle is inserted into the sample container for ventilation. A mixing mechanism is arranged below the filtering mechanism and is driven by a mixing motor. The sample container is accommodated in a seat and is driven by the mixing motor. A test tube carrying mechanism is arranged below the mixing mechanism, and has an accommodating hole for a test tube. A jacking mechanism is arranged below the mixing mechanism, and is driven by a jacking motor. When the jacking mechanism moves upwards, a jacking platform is pressed against the bottom of the test tube, so that the test tube is butted against the bottom of the sample container, and a sample preparation in the sample container is dripped into the test tube.

Aspects of the present invention comprise a container that is stably rotatable. In embodiments, a container may rotate about a central axis, wherein the container comprises at least one feature at the central axis that facilitate rotation and at least one other lateral feature that provides stability to the container to reduce the occurrence of tipping or spilling while the container is moving.

A mixer includes a mixing container held in a machine stand, with an outlet opening in the bottom of the mixing container, and a closure cover which can be reciprocated between a closed position in which the closure cover closes the outlet opening and an opened position in which the closure cover does not close the outlet opening. The closure cover is connected to the machine stand by way of a four-bar linkage including four rotary joints, wherein a first and a second rotary joint of the four-bar linkage are arranged on the closure cover and a third and a fourth rotary joint of the four-bar linkage are arranged on the machine stand.
