A method in which a medium viscous to highly viscous fluid and/or a medium viscous to highly viscous suspension are/is mixed by means of an agitator device that is driven by a drive shaft, wherein

the fluid and/or the suspension are/is brought into a multi-dimensional flow by means of a close-clearance stirring blade (14) of the agitator device, and a flow resistance is minimized along a shaft direction in a shaft proximity.

A reactor for coating particles includes a stationary vacuum chamber having a lower portion that forms a half-cylinder and an upper portion to hold a bed of particles to be coated, a vacuum port in the upper portion of the chamber, a paddle assembly, a motor to rotate a drive shaft of the paddle assembly, a chemical delivery system to deliver a first fluid, and a first gas injection assembly to receive the first fluid from the chemical delivery system and having apertures configured to inject a first reactant or precursor gas into the lower portion of the chamber and such that the first reactant or precursor gas flows substantially tangent to a curved inner surface of the half-cylinder.

A mixing device and methods for making bone cement. A piston (156) of the mixing device is located in a first region (158) of a chamber (112) such that a mixing paddle (154) rotates to mix bone cement components at a first pressure to make a bone cement mixture. The piston (156) is moved passed an inlet opening (136) to be located within a second region (160) of the chamber (112) to compress the bone cement mixture to a second pressure greater than the first pressure to compress the bone cement mixture and make the bone cement. The bone cement may be transferred to a delivery device. The mixing device may include features that automatically initiate the compression and transferring phases after completion of the mixing phase, and further include features that automatically terminate the operational cycle. A three-step intuitive workflow utilizing the mixing device to improve efficiency in the surgical suite is also disclosed.

A mixing container with an internal mixing blade has an extraction funnel, a main housing, a rotatable base cap, a mixing blade and a gear mechanism. The extraction funnel has a first end with a maximum diameter and narrowing to a second end of a minimum diameter at a neck portion. The main housing includes a mixing chamber. The rotatable base cap with an internal gear is attached to and is rotatable relative to the main housing. The mixing blade has a plurality of prongs extending from a shaft. The prongs are in the mixing chamber and the shaft extends through an opening in the main housing to inside the rotatable base cap. The gear mechanism has at least one gear, each of the at least one gears is connected to or intermeshed with the internal gear of the base cap and the gear of the shaft end.

The present set of embodiments relate to a system, method, and apparatus for culturing cells within a cell culture vessel having a mixing element. The cell culture system includes a flexible portion and a mixing element disposed therein. The mixing element includes a suspended foldable portion. The system is configured to reduce shear stress on cells without compromising mixing efficiency. This reduction is accomplished by using a mixing element having a large surface area allowing for reduced rotational speeds. The system is collapsible for ease of transport and disposal. The flexible portion collapses and the foldable portion folds to minimize the volume of the system while not in operation.
