Current cartridge-style mixers due not have the ability to measure mixing performance nor determine the need for maintenance based on performance. Risks of non-homogeneous mixing and insufficient maintenance can exist with cartridge-style mixers. A mixing system comprises a mixing apparatus, a first switch, a magnetic switch, and a controller. The mixing apparatus is configured to receive a cartridge and to mix a material. The mixing apparatus comprises a linear actuator configured to translate the cartridge or plunger in a vertical direction and a spindle configured to rotate a plunger. The first switch is configured to measure a number of strokes per unit of time of operating the linear actuator. The magnetic switch is configured to measure a speed of the spindle. The controller is configured to receive one or more mixing parameters, actuate the spindle and the linear actuator, and actuate a light to indicate if there was sufficient mixing.

The present disclosure relates to a sample preparation device and a related method. The sample preparation device includes a sample preparation module having a holder configured to hold the sample container, and an actuator coupled to the holder. The actuator is configured to cause the holder to repeatedly change a position of the sample container a set number of times in order when the sample container is held by the holder. The sample preparation device also includes a staging module configured to hold the sample container for a set period of time. The staging module includes a rack that holds the sample container when the sample container is released from the holder. The set period of time is sufficient to allow the blood in the sample container to further clot.

A mixing and paint-making device and method for making paint are described. Embodiments of the paint-making device include a first and second palette hingedly coupled to a base. The base includes a paint pot shaking component configured to agitate and/or translate a paint pot. The paint pot shaking component includes a series of gears and pistons that interact to produce a shaking motion for a paint pot coupled to the paint pot shaking component. In one embodiment, the paint pot shaking component includes a crank gear adjacent a combination gear that contacts a slide crankshaft. The slide crankshaft is coupled to a slide crank arm that is secured by slide bracket coupled to the base. A paint pot harness holds a paint pot during agitation and moves in an upward and downward motion corresponding to the motion of the slide crank arm.

An apparatus configured for mixing the contents of one or more fluid containers includes a fluid container support platform configured to hold one or more fluid containers. The fluid container support platform is configured to index the container to one or more specified locations and to be moved in an orbital path about an orbital center independently of the rotation about the central axis of rotation. The apparatus further includes an indexing drive system configured to effect indexing movement of the container support platform and a vortex drive system configured to effect powered orbital movement of the container support platform about the orbital center. An evaporation limiting insert placed within containers reduces exposure of the fluid contents of the container to atmospheric air, thereby reducing susceptibility of the fluid contents to evaporation.

In one embodiment, a mixing device includes a sleeve that forms an inner space configured to receive a sample container, a housing associated with the sleeve, a mixing element contained within the housing that is configured to mix liquid contained within the sample container, and an activation element configured to activate the mixing element when the activation element is triggered.

A dissolving and mixing unit for automatically dissolving and mixing medicines includes: a support; a dissolving and mixing device mounted on the support and including two piercer bases and at least one dissolving and mixing channel, wherein each dissolving and mixing channel includes two piercers and an elastic infusion hose connecting the two piercers, and the two piercers of each dissolving and mixing channel are mounted on the two piercer bases respectively; a peristaltic pump mounted on the support and configured to squeeze the elastic infusion hose; first and second bottle-containing modules mounted on the support and configured to hold first and second medicine containers respectively; and a movement mechanism configured to drive at least one of the first bottle-containing module and one piercer base to move, and configured to drive at least one of the second bottle-containing module and the other piercer base to move.

The present invention relates to a bioreactor assembly comprising a plurality of trays (30) for holding a cell culture bag, a holder (2) on which the trays are mounted side by side to form a first series of trays rocking mechanism (4) for rocking the trays, the rocking mechanism (4) being operatively connected to each of the trays (30).

The invention also relates to a bioreactor system (100) comprising at least one bioreactor assembly.

A mounting apparatus for holding tubes of samples for processing by a homogenizer. The mounting apparatus includes a processing plate and at least one cassette, with the plate for mounting to the homogenizer, the cassette for mounting to the plate, and the tube for holding by the cassette. In some embodiments, the cassette includes one or more tube-retention assemblies for removably securing the tube against axial, lateral, and/or rotational movement, for example, using centrifugal forces of the homogenizer for retention assistance. In some embodiments, the cassette is removably mounted to the plate, for example, using centrifugal forces of the homogenizer for retention assistance. And in some embodiments, the tube can be replaced in the cassette with the cassette mounted to the plate adjacent an access opening through which the tube can pass, while centrifugal forces assist in retaining the tubes in the cassette during operation of the homogenizer.

A ring gear used in a mechanical exfoliation apparatus having a plurality of canisters to hold particulate material and media is provided. The ring gear having an inside surface, an outside surface, a front face, and a back face. The inside surface defining a plurality of beveled gear teeth and the outside surface defining a plurality of recesses that are configured to accommodate the plurality of canisters of the mechanical exfoliation apparatus.

A method of heating and mixing contents is disclosed that combines heating and agitating of a bottle and its contents in order to achieve even warming, as well as, mixing the contents of the bottle.
