Containers for the production of a foamed sclerosant composition are provided. The containers includes a container body for foaming having one or more sidewalls extending between a top and a bottom of the container body, a foaming space being defined in an interior of the container body. Further, the foaming space contains a mixing component configured for rotating, particularly on the bottom of the container body, and including a magnetic part and a shape suitable for mixing. The container also includes a female coupling member for mating with a tip of a syringe, such that the syringe can be used for extracting the foamed sclerosant composition, and the container includes at least one opening which is covered by a gas-permeable barrier.

A magnetically-coupled liquid mixer has axial and radial directions, and comprises: a drive mount to be secured to a wall of a mixing tank and having a stationary closed-end cylindrical casing arranged in the axial direction and configured for protruding into the tank, a tank-external drive rotor having a rotatable first magnet array and configured to be inserted in the cylindrical casing, and an impeller configured for being rotatably-mounted on the cylindrical casing and having a plurality of radially extending blades and a second magnet array. The first and second magnet arrays in an assembled state of the mixer are configured for enabling rotary torque to be transferred from the drive rotor to the impeller by magnetic coupling between the first and second magnet arrays. An upper portion of at least one blade is curved/angled in an intended direction of rotation to help move liquid axially downwards during impeller rotation.

A mixing system for use in a process bottle for mixing its contents, the mixing system including a low volume magnetically-driven mixer mounted at the bottom of the bottle. The mixer may have vanes and lower grooves, or no vanes and grooves on both upper and lower faces. The mixer has a microsized three-dimensional solid inanimate body to enable insertion through relatively small mouth openings at the top of conventional reactor bottles. Methods of assembly are also disclosed which involve passing the microsized mixer through an open mouth of a process bottle and coupling the mixer with a bearing assembly at the floor of the bottle. The bearing assembly includes fixtures sealed around a hole in the floor of the bottle.

A magnetic mixing apparatus is disclosed. A magnetic mixing apparatus according to one embodiment of the present invention comprises: a shaft which passes through a driving motor unit and which is rotatably coupled to the driving motor unit; a first housing which is coupled to one side of the driving motor unit and which is provided outside a stirring container to accommodate an upper part of the shaft; a rotary rotor which is coupled to the end of the shaft at a stirring container side during normal operation and which has a first permanent magnet; and an impeller unit which is arranged inside the stirring container and which has a second permanent magnet magnetically coupled to the first permanent magnet during normal operation, wherein the first housing includes a magnetic separation rotary rotor support part formed to protrude inward so as to support, from the downward direction, the rotary rotor, which is down-driven so as to move downward from the shaft, when there is magnetic separation by which magnetic coupling is released through magnetic deformation of the first permanent magnet and/or the second permanent magnet.

A rotating mechanism of a handicraft is provided, including: a cover body for covering a water lamp handicraft; a support member, where an end is connected to the cover body, and an other end includes an outer rotating groove; a water stirring impeller, located between the cover body and the support member, a rotating body, sleeved on the support member and having an inner rotating groove corresponding to the outer rotating groove; and a ball ring, located between the outer rotating groove and the inner rotating groove, where the rotating body is rotatably connected to the support member through the ball ring.

A sparger assembly (700) for a bioprocessing system includes a base plate (710) and at least one aeration manifold (712, 714) removably connected to tire base plate. Each aeration manifold includes at least one inlet for receiving a gas and a plurality of gas outlet openings for delivering tire gas to a fluid within the bioprocessing system. An impeller assembly (740) fora bioprocessing system includes a hub and at least one blade (742) operatively connected to the hub. The at least one blade includes a first portion connected to the hub and extending generally vertically, and a second portion extending at an upward angle from tire first portion.
