Patent ID: 8123397

Claim:
A disposable container for the mixing of media comprising a flexible mixing vessel ( 1 ) having a vessel wall ( 17 ) with an inner surface ( 10 ) facing into an interior of the vessel ( 1 )and at least one stirrer within the vessel ( 1 ), the vessel ( 1 ) having at least one closable opening ( 2 , 3 , 4 ) for introduction and/or removal of the media directly into an open, main body portion of the vessel ( 1 ), a first sensor ( 5 ) for measurement of at least one parameter of the mixture, and at least one second sensor ( 6 ) for measurement of the same parameter arranged at a distance from the first sensor ( 5 ), the first sensor ( 5 ) being located in an area of one third ( 9 ) of the vessel ( 1 ) which is located furthest away from the opening ( 3 ) for the introduction of the media, and the second sensor ( 6 ) is located in an area of one third ( 11 ) of the vessel ( 1 ) in which the opening ( 3 ) for introduction of the media is located for measurement and comparison of the parameter at more than one location of the vessel ( 1 ), and further characterized in that each of the sensors ( 5 , 5 ′) is attached to the inner surface ( 10 ) of the vessel wall ( 17 ) via a sensor mount ( 511 , 513 , 514 ), the sensor mount ( 511 , 513 , 514 ) having a rearward surface element ( 518 ) resting against the inner surface ( 10 ) of the vessel wall ( 17 ) and forming a seal, the sensors ( 5 , 6 , 7 , 8 ) being embedded in a surface of the sensor mount ( 511 , 513 , 514 ) facing away from the rearward surface element ( 518 ) whereby the seal between the rearward surface element ( 518 ) and the inner surface ( 10 ) of the vessel wall ( 17 ) ensures sterility in the interior of the container.
