The present invention relates to a magnetic mixer capable of minimizing mixing of foreign substances, which are generated in components of the magnetic mixer, of a liquid to be mixed, having a simple structure for cleansing a structure supporting an impeller shaft, and capable of securing a sufficient output when a large-scale mixing system with an impeller shaft is configured; and a mixing system including the same.

A method for controlling fluid ratio accuracy during a dual flow injection with a powered injection system is described. The method includes predicting a first capacitance volume of a first syringe comprising a first medical fluid and a second capacitance volume of a second syringe comprising a second medical fluid with a first capacitance correction factor and a second capacitance correction factor, respectively, selecting a ratio of the first medical fluid and the second medical fluid to be administered to a patient in the dual flow injection, determining a relative acceleration ratio of a first piston of the first syringe and a second piston of a second syringe based on the predicted first capacitance volume and the predicted second capacitance volume, wherein the relative acceleration ratio is selected to maintain the selected ratio of the first medical fluid and the second medical fluid during the dual flow injection, and injecting a mixture of a first medical fluid and a second medical fluid having the selected ratio with the powered injection system.

The present disclosure relates to a container (1) for mixing paint comprising a paint cup (2) comprising a base portion (3) and sidewall portions (4) enclosing a receptacle volume (5), and having an opening (6) opposite to the base portion(3); a rotatable mixing element (17) disposed in the receptacle volume (5); and a coupling means (19) for operatively connecting the rotatable mixing element (17) to an actuator (30) configured to drive the rotatable mixing element (17).
