A mixing unit (100) for mixing of fluids is disclosed. The mixing unit (100) includes a mixing chamber (102) for holding one or more fluids and a driving assembly (104) operatively engaged to the mixing chamber (102). The driving assembly (104) is configured to oscillate the mixing chamber (102) for mixing the one or more fluids. The mixing chamber (102) of the mixing unit (100) enables better mixing of fluids in a convenient manner. Further less amount of cleaning fluids may be only required for cleaning the mixing chamber (102) after the mixing process. The mixing unit (100) can be used for mixing amino acids with different fluids however this unit can be used for mixing other fluids as well.

A linear reciprocating actuator for mixing, agitating, separation, continuous sampling and/or harvesting or filtration, gas mixing, and various other applications. The actuator may have a housing closed on one end, and attached to a vessel in a hermetically-sealed manner such that it is part of the fluidic envelope of the vessel. An agitation device may be attached to a shaft which is partially surrounded by the housing, or the agitation device may surround the housing where the housing protrudes into the vessel. The actuator enables agitation of the contents of a hermetically-sealed vessel without mechanical coupling from outside the fluidic envelope of the process. The agitation device is solely acted upon by a magnetic field, is contained entirely within the fluidic envelope of the process, and is not attached to the vessel in any way. The magnetic flux which drives the agitation device passes through the housing.

An orbital shaker device (1) for biotechnological and/or biomedical applications comprises a frame (10), a platform (15) for receiving biotechnological and/or biomedical containers (50), eccentric couplings (13, 14) for allowing an orbital movement of the platform (15) relative to the frame (10), counterweight units (17, 18) for balancing the orbital movement, and at least one motor (19) for driving the eccentric couplings (13, 14). The device comprises two eccentric couplings (13, 14) arranged near respective opposite edges (27, 28) of the platform (15), while each counterweight unit (17, 18) is arranged approximately in the plane of the combined center of gravity of the platform (15) and the containers (50). Furthermore, both eccentric couplings (13, 14) are driven by the motor (19) or motors, either directly or indirectly. In this way, an optimal vibration compensation is achieved while allowing an imaging unit (40) to be mounted underneath the platform (15).

A multi-phase cosmetic composition mixing pack for mixing immiscible components of a multi-phase cosmetic composition such that they are temporarily miscible includes a container for holding the multi-phase cosmetic composition that has a first open end. The mixing pack further includes a mixing assembly disposed within the container for mixing immiscible components of the multi-phase cosmetic composition such that they are temporarily miscible, and an actuator assembly for actuating the mixing assembly. The actuator assembly comprises a stem receivable within the first open end of the container. The stem includes a cam surface extending along at least a portion of a length of the stem, and a cam follower surface defined on the mixing assembly, wherein linear reciprocating motion of the stem causes rotation of the mixing assembly.

A dynamic mixer comprises a mixing chamber having a plurality of inlets and an outlet as well as a mixing element rotatably arranged in the mixing chamber. The mixing takes place by a to and fro movement of the mixing element.

Method of robot control is disclosed that includes the steps of: providing a user interface for introducing data indicative of a drug to be subjected to a reconstitution process; accessing an internal data base for outputting, for a selected drug, a list of primitive movements P1, P2, . . . Pi, . . . Pn to be used in the reconstructing process; operating the robot for executing sequentially the primitives and moving a container according to the instructions of the primitives; measuring, during the movement of the container under robot action, physical positions in the space and dynamic parameters of the container creating a list of registered data; comparing the measured positions in the space and the dynamic parameter with the corresponding ones of the primitive movements for selecting a list of eligible primitives if a sufficient approximation level is reached; elaborating selected eligible primitives together to generate instructions for the robot allowing a complex movement encompassing the simple movements; and using the robot for shaking the container according to the complex movement.

A jar or other storage container with an integrated stirring device, where the contents of the jar or storage container can be stirred and mixed together without having to completely open the jar or storage container. The core components in one embodiment are a top portion that contains external threads, a lid portion which contains internal threads, a spindle with an etched self-reversing screw pattern, a hub, one or more stirring blades, and a nut. The stirring blades have one end attached at a hub that is free to rotate on the spindle, the other end is attached to a nut that can travel up and down the self-reversing screw pattern, and the spindle is fixed to the lid portion. The surface area of the stirring blade(s) can be changed to accommodate different thicknesses and viscosities of different fluids and semi-fluids placed in the storage container.

Analyzers are described that control sample agitation by detecting vibration acceleration and using feedback to control the agitation and also alert to the presence of abnormal agitation. An embodiment provides an analyzer comprising a liquid agitation unit; an agitated liquid analysis unit; and a unit that controls the agitation unit. The agitation unit includes a vibrator of a liquid container and a detector of vibration of the container and that outputs a signal to the control unit, which responds by regulating the vibrator.

Disclosed is a system for production of a cosmetic product including: at least one first single-use packaging unit including a preset quantity of a first phase of a cosmetic product, at least one second single-use packaging unit including a preset quantity of a second phase of a cosmetic product, a machine including a mixer inside of which the mixture of the preset quantity of the first phase and the preset quantity of the second phase is done automatically in order to end up with a cosmetic product directly consumable by the end consumer. The mixing is done in a manner such that neither the first phase nor the second phase are in direct contact with any part of the mixer which is not single use, thus avoiding dirtying the mixer.

A split casing fluid device includes a reaction chamber including a first and second casings having a portions of a stator, a rotor rotatably mounted inside the stator and having a plurality of fluid-interacting features, the rotor exterior surface and the stator define a fluid passageway therebetween, an inlet into the reaction chamber in fluid communication with the fluid passageway, and an outlet from the reaction chamber in fluid communication with the fluid passageway. Removal of a casing creates an opening in the reaction chamber sized to allow passing the rotor through the opening. In some embodiments, the casings span the entire length of the rotor and removal of at least one casing creates an opening in the reaction chamber sized to allow removal of the rotor in a perpendicular direction to the longitudinal axis. The fluid device may be a cavitation generator with a rotor having cavitation-inducing features.
