A chemical mixer tool for use in a storage drum is described. The chemical mixer tool typically comprises a mixer housing assembly in which one end of a mixer shaft is secured, the distal end of the mixer shaft having at least one collapsible impeller assembly removably attached thereon. The chemical mixer tool is configured to be removably secured to the top portion of the storage drum, with the distal end of the mixing shaft extending into the interior of the storage drum.

The invention relates to a device for producing a multi-component mixture, comprising a mixing chamber and a mixing device, wherein the mixing device has a stirrer which is arranged in the mixing chamber and which is rotatably driven about an axis of rotation L, wherein a temperature control channel system for controlling the temperature of the stirrer and through which a temperature control medium can flow is arranged inside the stirrer.

A kit for a bioreactor includes a bioreactor bag, a connector, an impeller assembly, and a clamp. The connector defines an aperture. The connector also includes a welding surface extending between a first end and a second end, with the second end including an outwardly extending flange. The welding surface can be heat-sealable to the bioreactor bag. The impeller assembly includes a shaft and a blade configured to pass through the aperture. The impeller assembly includes an impeller flange configured to contact the flange of the connector when the impeller shaft is received in the aperture. The impeller assembly also includes a bearing supporting the impeller shaft. The clamp is configured to secure the connector flange to the impeller assembly. Preparing a bioreactor includes welding the connector to the neck of the bioreactor bag and then inserting the shaft and blade through the aperture into the bioreactor bag.

A submersible agitator device for circulating drinking water includes a submersible motor including a cylindrical housing, from one end of which there extends a shaft, a hyperboloid agitator mounted on the shaft, a frame with a plurality of supports extending along the housing and connected to the housing, wherein the supports have radially outwardly angled bend portions, which extend over a peripheral edge of the hyperboloid agitator body in order to support the frame on a base, and a flow-guiding element, which is annular in plan view and which is mounted on the bend portions of the supports.

A heating and stirring device is described herein that comprises a base configured to removably attach to one of a beverage container and a beverage container lid, the base containing a power supply, a controller, and a motor, and an agitator having a body and a length with a first end portion configured to be supported by the base, and a second end portion, wherein the first terminal end is configured to be outside of the beverage container and the second end portion is configured to be inside of the beverage container. Corresponding systems and methods also are disclosed.

A system and method for stirring molten material such as glass are provided. To prevent sagging of a cover of a stirring system, a portion where deformation or sagging may significantly occur is suspended by a suspension system, so that local sagging and deformation of the cover is suppressed. As a result, a crack which may occur in the cover is suppressed, and therefore, contamination of the molten material is likewise suppressed.

The invention relates to a mixer insert having a support rod element and at least one vortexing element and a rotary drive connection structure, wherein the mixer insert, for insertion into a tubular passage element, and together therewith, is adapted to a device for mixing at least two fluid components to be placeable by means of the rotary-drive connection structure in drive connection with a driveshaft of the device, when the mixer insert is inserted into the passage element and the passage element is placed in fluid-tight flow connection with at least two component feed lines of the device, characterized in that the rotary-drive connection structure has a bore hole having a bore hole wall which are adapted to a thread on the driveshaft in such a manner that the bore hole, for producing the drive connection, can be screwed onto the thread, wherein the bore hole wall is shaped by the thread. The invention also relates to such a device for mixing and also to a system of such a device and such a mixer insert.
