An agitation device for agitating products held in wells of sample vessels or a laboratory microplate is disclosed. The device is arranged to retain a microplate and to agitate an agitation member comprising an array of agitation projections which enter the wells of the microplate. The agitating motion can be horizontal and damping means can be provided between an actuator and parts of the device to reduce overall vibrations. A related method of agitation of microplate or sample vessel contents is described. A novel arrangement for receiving a replaceable agitation member for the device is also disclosed.

Containers including internal mixers and actuators assemblies and related methods are generally described. In some embodiments, a container may include a mixer and an actuator, at least one of which may be located inside of the container. The actuator may actuate the mixer to induce flow within the container and mix the contents of the container with a low volumetric footprint and high mixing efficiency. In some embodiments, the actuator may be configured to deform the mixer, which may include one or more features which may be deformed out of plane in a Kirigami or Origami fashion. The actuator and mixer may be arranged in series or in parallel. The actuator may be used without a mixer to induce flow within the container. The actuator may be driven pneumatically, hydraulically, electrically, and/or in any other suitable manner.

A concrete vibrator can further reduce vibration. The concrete vibrator includes a motor, a flexible shaft drivable by the motor, an unbalanced weight drivable with the flexible shaft, a flexible hose at least partially covering the unbalanced weight and the flexible shaft, a body housing accommodating the motor, and an elastic member between the body housing and the flexible hose.

A tattoo ink mixing apparatus has a housing having a cavity, a plunger movable between a first position and a second position, and a dynamic member disposed in the cavity and adapted to engage with the plunger distal end. The dynamic member moves in response to movement of the plunger and alternatively creates a suction force and an expulsion force in the opening of the distal end of the housing as the plunger moves between its first and second positions.

A new mixing device for mixing solids and medium to highly viscous food ingredients with liquid in a shaker bottle. The mixing device has an agitator with a center portion and distal portions of larger diameter than the center portion. The agitator is insertable within a hand-held, shakeable container. The agitator is composed of a framework arranged to provide voids to allow for flow of liquids, powders, and other materials into and out of portions of the agitator. The mixing device also has a weighted member attached adjacent to or within the center of the agitator that increases the momentum of the mixing device when in operation. The weighted member may have a metal core and polymer exterior.
