Abstract: The sterilized-flexible bag like disposable container for mixing of buffer/fluid/solid medium in pharmaceutical/biotechnological sterile liquids, comprises lockable openings (2, 3, 4) for introducing and discharging of the medium, and sensors (5, 6, 7, 8) for measuring pH value and/or conductivity and/or temperature of the mixture. The sensors are arranged in an interval to the neighboring sensor. Two sensors are arranged in the first part of the container. One of the sensors is arranged in a third part of the container, in which an agitator (13) is arranged. The sterilized-flexible bag like disposable container for mixing of buffer/fluid/solid medium in pharmaceutical/biotechnological sterile liquids, comprises lockable openings (2, 3, 4) for introducing and discharging of the medium, and sensors (5, 6, 7, 8) for measuring pH value and/or conductivity and/or temperature of the mixture. The sensors are arranged in an interval to the neighboring sensor. Two sensors are arranged in the first part of the container. One of the sensors is arranged in a third part of the container, in which an agitator (13) is arranged and another sensors are arranged in the third part at a distant from the agitator. One of the sensors is arranged in a middle part of the container. A higher number of sensors are arranged in an area with low turbulence flow than in an area with high turbulence flow. The sensors are attached in a container wall (17) by a sensor support, which adjoins a rear sub-surface or back surface turned away to the sensor at an inner wall of the container. The sensor support with a central piece is passed into the container wall through an opening and is fixed at the wall through a clamping part that is connectable with the central piece. The container wall is climbed between the rear sub-surface of the sensor support and a contact surface of the clamping part, which is turned to an external wall of the container. The sub-surface lies at the inner wall of the container wall in tight manner. The clamping part is engaged and boltable with the central piece. The sub-surface or the contact surface exhibits ring-shaped tightening portions that interfere transversely to the container wall. The tightening portions of the sensor support and the clamping part are co-coordinated on each other. An electrical or optical connection of the sensor to sensor-electronics or control unit (14) takes place at outside of the container by the central piece of the sensor support. The sensor support exhibits an electronic or optical transmitter unit, which is connected with the sensor. The transmitter unit wirelessly communicates with reception unit arranged outside of the container. The sensor support exhibits another central piece at its back surface, and the central piece is positively surrounded by a projection of the container. An independent claim is included for a procedure for mixing of medium in a container.
