Provided are an enclosed stirrer using intermittent resonance and a method. The enclosed stirrer comprises: two pairs of parallel tension springs (1), a fixing bracket (2), an elastic cantilever beam (3), a cantilever beam pressure clamping device (6), an eccentric motor (4), an arc-shaped cushion block (5), and an enclosed container (8). The enclosed container (8) is mounted on the fixing bracket (2) by the tension spring (1). The elastic cantilever beam (3) is installed below the enclosed container (8) and is axially parallel to the enclosed container (8). One end of the elastic cantilever beam (3) is mounted on the fixing bracket (2) as a clamping end, the other end of the elastic cantilever beam (3) is connected to the eccentric motor (4) as a movable end. The arc-shaped cushion block (5) is connected above the eccentric motor (4). The arc-shaped cushion block (5) reciprocally strikes the bottom of the enclosed container (8) during operation of the eccentric motor (4).

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 apparatus for substantially horizontally oscillating one or more vessels containing a liquid, a solid, or a mixture thereof that operates to thoroughly disrupt and mix solid and liquid substances in vessels, like test tubes. The apparatus provides superior mixing through oscillation of the vessels both horizontal and vertical directions through the use of one or more springs and rotating mechanical components. The apparatus includes a circular rotating ring having a toothed circumference that rotates horizontally, at least one vessel support having a compartment configured to hold the one or more vessel vessels and a spring attached to the housing and in constant contact with each of the one or more vessel supports.

A cell culture method conducted by supplying a culture medium together with cells to a container (1), an upward movement step in which the container is moved upward to a position higher than the initial position and a downward movement step in which the container that has been moved upward is returned to the initial position, and vibration is applied to the container that has been returned to the original position are repeated, whereby a content liquid in the container is stirred. As a result, a good culture environment is maintained by conducting stirring such that distribution of cells and concentration of components of a culture medium in a content liquid become uniform, while reducing damage on cells by shear stress, and adherence of cells to the inner wall or excessive agglomeration is suppressed by stirring, whereby proliferation of cells can be promoted.

A liquid storage apparatus including: a stirring portion including a storage unit configured to store liquid and a drive unit configured to drive the storage unit; and a storage portion configured to store the stirring portion, the storage portion being opened and closed by an opening and closing member, wherein in a case where a stop condition relating to a state of the opening and closing member is satisfied, rotation of the storage unit by the drive unit is stopped.

A liquid agitating apparatus includes a first storing container configured to store a first liquid, a first agitating mechanism configured to agitate the first liquid in the first storing container by causing the first storing container to undergo a first movement, a second storing container configured to store a second liquid different from the first liquid; and a second agitating mechanism configured to agitate the second liquid in the second storing container by causing the second storing container to undergo a second movement different from the first movement.

A liquid stirring apparatus comprises storage means for storing a liquid; and driving means for performing a rotation operation of rotating the storage unit. The rotation operation includes a stop operation of stopping rotation of the storage means at a plurality of stop positions. The plurality of stop positions include a first stop position at which a stop time is a first time, and a second stop position at which the stop time is a second time different from the first time.
