A dual centrifuge (10) embodies the following: a driveshaft (16), a rotor (20), which is mounted on the driveshaft (16) and which can be removed axially in a removal direction (E), for a dual centrifuge, having at least one rotational unit (30); an opening (18) in the rotor (20), wherein an end region (16a) of the driveshaft (16) at least engages into said opening; and an additional drive mechanism (32) for the rotational unit or the rotational units (30). The dual centrifuge additionally has a design for operating various additional types of rotors; however, only one rotor (20, 40, 50) can be arranged on the driveshaft (16) at all times. The various rotor types (40, 50) are also adapted to the additional drive mechanism (32) for the rotational units (30) such that the function is not adversely affected. A design for operating at least one angular head rotor (40) and a swing-out rotor (50). For this purpose, the driveshaft (16) and the various rotor types (40, 50) are adapted to each other. The bearing (16), the driveshaft (16), and the various rotor types (40, 50) are adapted to one another such that each non-dual rotor (40, 50) has a geometry that is measured such that when the rotor (40, 50) is mounted, a drive device (32a) of the additional drive mechanism (32) for the rotational units (30) is arranged so as to not contact the mounted rotor (40, 50).

A customized skin care composition. The skin care composition includes a base composition comprising one of an aqueous alcohol composition or an aqueous emulsion. The skin care composition further includes at least two booster compositions selected from the group consisting of a first grade exfoliating agent; a second grade exfoliating agent, the second grade exfoliating agent providing greater exfoliating than the first grade exfoliating agent; a first grade whitening agent; a second grade whitening agent, the second grade whitening agent providing greater whitening than the first grade whitening agent; a first grade anti-aging agent; and a second grade anti-aging agent, the second grade anti-aging agent providing greater anti-aging effects than the first grade anti-aging agent. The base composition and the at least two booster compositions have been mixed to form a composition that is stable and has efficacious concentrations of active ingredients corresponding to skin conditions of a consumer.

The disclosure provides methods and compositions for providing shatter formulations taking the form of crystalline polymorphs, where methods of preparation include preparing tetrahydrocannabinol acid (THCA) powder followed by decarboxylating THCA and removal of terpenes.

A rotation mixer including a housing, a drive unit coupled to the housing, a carriage mounted on the drive unit for rotation relative to the housing, and a basket mounted for rotation relative to the carriage. The basket receives material to be mixed. The carriage includes an arm and a drive line coupled to the arm. The arm is mounted on the drive unit for rotation about a first axis relative to the housing, and the drive line converts rotation of the arm into rotation of the basket about a second axis relative to the arm during use of the rotation mixer. The drive line illustratively includes a belt and plurality of pulleys upon which the belt travels in a continuous loop, the belt engaging with a gear on the basket to cause rotation of the basket.

Method and apparatus to agitate a liquid are disclosed herein. An example apparatus includes a carrier having a base that includes a ridge extending from the base and a collar extending from the base. The example apparatus also includes a container supported on the base, the container movable between (A) a locked positon in which the ridge fixedly engages the container to non-rotatably couple the container to the base and (B) an unlocked position in which the container is disengaged from the ridge and the container is rotatable about the collar.

A system and method is provided for providing a cosmetic composition to a user. The system includes an apparatus configured to dispense at least one cosmetic composition into a output container; a user interface configured to receive information about the user; and circuitry configured to receive the information about the user and determine one or more cosmetic compositions to be dispensed into the output container based on the information about the user received at the user interface.

An apparatus is provided for dispensing a cosmetic composition, including: a cartridge holder configured to hold at least one cartridge that stores a cosmetic composition, the cartridge holder being configured to move the cartridge to a predetermined location; a container receiving area configured to hold a output container beneath the predetermined location; circuitry configured to determine the cosmetic composition in the cartridge holder, control the cartridge holder to move the cartridge holder to the predetermined location based on the determination, and control the cartridge to dispense the cosmetic composition into the output container; and a mixer configured to hold the output container and subject the output container to a predetermined movement to cause contents of the output container to mix together.

The present disclosure relates to the field of mixing and dispensing apparatuses. A mixing and dispensing apparatus of the present disclosure facilitates automatic mixing and dispensing of a semi-liquid form of a powder material when mixed with a fluid. The apparatus comprises a mechanism to hold and rotate a cartridge, an actuation device, and an injection unit. The cartridge consists of the powder material to be mixed with the fluid. The mechanism rotates the cartridge about a primary axis of rotation and a secondary axis of rotation to uniformly mix the powder material with the fluid. The actuation device performs a piercing stroke to pierce one end of cartridge, and a dispensing stroke to dispense the semi-liquid form of the powder material through other end of the cartridge. Further, the injection unit is disposed within the actuation device to inject a pre-determined quantity of fluid following piercing stroke.
