摘要:
An agitator apparatus for a mixing vessel having a rotating member and one or more impellers coupled to the rotating member, at least one of the impellers being collapsible so that the collapsible impeller is movable from a collapsed orientation to a deployed orientation relative to the rotating member. A limiting member may be used to prevent the collapsible impeller from opening beyond its fully deployed orientation.

A probe assembly includes a tubular sleeve having a passage extending between a first end and an opposing second end. The tubular sleeve is movable between an extended position wherein the first end and the opposing second end are spaced apart and a collapsed position wherein the first end and the opposing second end are moved closer together. A connector is secured to the second end of the tubular sleeve, the connector having an opening extending therethrough that communicates with the passage of the tubular sleeve, a sealing layer removably covering the opening of the connector. An elongated probe has a first end and an opposing second end, the second end of the probe being positioned within the passage of the tubular sleeve, the second end of the probe being configured to pass through the opening of the connector when the sealing layer is removed therefrom.

摘要:
A method of mixing including providing a flexible container which comprises at least two components, assembling the components from outside the flexible container to form a centrally disposed magnetic driven shaft with at least one impeller, whereby the integrity of the flexible container is maintained, filling the flexible container having the centrally disposed magnetic driven shaft with one or more ingredients of the contents to be mixed; engaging a magnetic element of the centrally disposed magnetic driven shaft with an external magnetic drive element; analyzing the contents of the flexible container using at least one sensor or a sampling line on the flexible container; and draining the contents of the flexible container through a drain port at the bottom of the flexible container.
摘要:
A container with a flexible container wall, in particular a disposable bioreactor, with a container interior in which a a mixer is arranged at one end of a mixer shaft which is passed through the container wall and is drivable from the outside, wherein the mixer shaft and/or mixer is/are designed such that it/they are foldable and such that it/they can be stabilized from the outside.

A system and method for custom coloring sealant is generally provided with one or more dispensing cartridges, containing a quantity of low viscosity sealant base solution, which in some embodiments is as fluid, or more-so, as common latex paint. One or more such dispensing cartridges are secured within a cartridge case. A coloring agent is added to the dispensing cartridge. The system may then be agitated by hand or in a mechanical agitator, such as a commercial paint shaker, until a desired color is attained. The sealant thickener may then be added and mixed by similar agitation of the system to obtain a non-sag, high viscosity sealant. Embodiments of the cartridge case are provided for use with various mechanical agitators and dispensing cartridges.
摘要:
A flexible bioreactor intended for culturing cells in a liquid medium, the bioreactor comprising a flexible wall forming a fluid impermeable bottom wall of the bioreactor when in use, wherein flexible parts of said flexible bottom wall are interrupted by at least one rigid element of said flexible bottom wall, the rigid element and the flexible parts being connected fluid tightly, and wherein the rigid element comprises measuring means allowing for non-invasive monitoring of cellular activity in said bioreactor when in use.

A mixing apparatus including a kinetic energy source, a mixing tank, a pivot guide, and transfer shaft is used to drive a mixing paddle through a circular path within a tank without substantial shaft rotation. Sleeved and sleeveless mixing paddles are provided in combination with sealable mixing tanks. A volumetric compensation system responsive to tank wall deflection is used to maintain the internal volume of a mixing tank within predetermined limits. One mixing apparatus includes multiple mixing shafts and paddles coupled to at least one kinetic energy source. Methods for fabricating sleeved paddle-containing mixing apparatuses are further provided.
