Abstract
The present disclosure relates to improved magnetic mixing assemblies and mixing system. The magnetic mixing assemblies can provide improved mixing action, ease of use, and low friction. The mixing assemblies can be adapted for use with a wide variety of containers including narrower neck containers and flexible containers.
Claims20
A magnetic impeller comprising:
- a rotatable element comprising a magnetic element and a post;
- an overmolded ring disposed about a perimeter of the rotatable element and sealing two base portions of the rotatable element together while encapsulating the magnetic element within the rotatable element;
- a plurality of blades, wherein the plurality of blades comprise first and second blades capable of rotation with the rotatable element to maintain their relative positional relationship, wherein the first blade is disposed above the second blade;
- and a plug adapted to retain the plurality of blades on the post,
- wherein the magnetic impeller is adapted to mix a fluid retained within a vessel, wherein the magnetic impeller is decoupled from the vessel.
2 more elements
A magnetic impeller comprising:
- a magnetic element;
- a rotatable element comprising a post and enclosing the magnetic element, wherein the rotatable element has a proximal end, an opposite distal end, and a contact flange disposed on a surface of the distal end, the contact flange comprising at least two ribbed portions an overmolded ring disposed about a perimeter of the rotatable element and sealing two base portions of the rotatable element together while encapsulating the magnetic element within the rotatable element;
- and
- a plurality of blades comprising first and second blades capable of rotation with the rotatable element to maintain their relative positional relationship, wherein the first blade is disposed above the second blade, and a plug adapted to retain the plurality of blades on the post, wherein the magnetic impeller is adapted to mix a fluid retained within a vessel.
1 more element
A mixing assembly comprising:
- a modular cart system comprising a first cart and a second cart,
- a magnetic impeller disposed within the vessel, the magnetic impeller comprising:
- a rotatable element;
- an overmolded ring disposed about a perimeter of the rotatable element and sealing two base portions of the rotatable element together while encapsulating a magnetic element within the rotatable element, wherein the overmolded ring further comprises a post;
- a plurality of blades comprising first and second blades capable of rotation with the rotatable element to maintain their relative positional relationship, wherein the first blade is disposed above the second blade;
- and
- a plug adapted to retain the plurality of blades on the post,
- wherein the magnetic impeller is decoupled from the vessel, and
- the second cart adapted to receive a magnetic drive selectively adapted to drive the magnetic impeller, wherein the first cart is adapted to couple with the second cart so that the magnetic drive is in a proper location for driving the magnetic impeller.
