A flow disturbance apparatus includes: a refrigerant pipe having a flow space in which refrigerant flows; and at least one disturbance member disposed inside the refrigerant pipe that is vibrated by the flow of refrigerant in the refrigerant pipe to disturb the refrigerant flowing in the refrigerant pipe.

The present technology provides a technology that liquid in round-bottom vessels is efficiently agitated. There is provided a vessel rack at least including a holder having a plurality of through-holes into which round-bottom vessels each having a closed-bottom tube shape are inserted, and a support having a plurality of supporting holes that are arranged facing to the through-holes and support bottoms of the round-bottom vessels, the bottoms of the supporting holes each having a bulge such that liquid in the round-bottom vessels forms a vortex at a time of agitation of the liquid. Also, there is provided an agitator of agitating liquid in round-bottom vessels at least including the vessel rack, a mounting unit that mounts the vessel rack, and a rocking unit that rocks the mounting unit, and the like.

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.

A system for the treatment of materials, to be selected from between materials in a fluid state (1) and particles suspended in a fluid material (1), comprising at least one upper kinematic pair equipped with two mechanical elements (2a, 2b; 2a, 2c), said kinematic pair being in contact with a material in a fluid state (1) or with particles suspended in a fluid material (1); motor means (5) to generate a pre-set relative velocity (v) between the elements (2a, 2b; 2a, 2c) of said kinematic pair, and tensioning means (8) to subject said kinematic pair to a pre-set pressure (P).

A device, which serves to separate particles of a bulk material, which is deliverable at an input location and is removable processed in different or at least approximately unitary particle sizes at an output location, includes at least one separating element, which has a metal separating plate with through-openings provided therein, which separating element can be provided with ultrasonic energy and for this purpose is connected to an ultrasonic transducer and which is held by a holding device. The holding device is a mounting shaft, which is held at one end or at both ends fixedly or movably, in particular rotatably and/or axially displaceable, and which at one end or at both ends is connected to an ultrasonic transducer, by means of which ultrasonic energy is couplable via the mounting shaft into the separating element, which is designed to be dimensionally stable.

An apparatus, vortex generator assembly and method for automated cell lysis and nucleic acid purification and processing. The vortex generator assembly includes sample holder having a lysis well, at least one wash well, and an elution well. The vortex generator assembly also includes a sample holder cover having a plurality of vibration rods for creating a vortex in the wells of the sample holder. The apparatus includes motor operating a rotating cam to cause the vibration rods to vibrate and create the vortex in a well holding fluid and magnetic beads, wherein the vortexing speed is sufficient to overcome the magnetic attraction between the beads and disperse the beads in solution, to collect nucleic acids such as DNA.

The present disclosure discloses a high-temperature aerogel heat insulation coating, preparation equipment and a use method for the preparation equipmen. A supporting leg frame is arranged on the outer side wall of the reaction tank; a storage cavity is formed in the upper outer box; a dispersing shaft is arranged in the storage cavity; dispersing blades are installed on the dispersing shaft; a dispersing motor and a material guiding pipe are arranged outside the upper outer box; an unloading mechanism is arranged under the reaction tank; and an exhaust hole and a feeding hole are formed in the outer part of the reaction tank.

A process and apparatus wherein a process material comprising two or more distinct phases are fed continuously to a tubular reactor containing an agitator wherein as the phases flow along the reactor the agitator displaces at least part of a first phase from its natural position to within a second phase where it is distributed within the second phase by the agitator and the agitator is designed to allow the first phase that is distributed within the second phase to flow naturally back towards its natural distinct position within the reactor as the phases pass through the reactor, useful for mixing and/or reacting liquid/liquid; gas/gas and liquid/gas mixtures as well as solid liquid mixtures.
