摘要： A mixing apparatus (1) for mixing a fluid and/or solid. The mixing apparatus includes a mixing container (100) having an interior in which the fluid and/or solid can be arranged. A feed-through passage (10) extends through a container wall (101) of the mixing container. A drive shaft (50) is fed through the feed-through passage, to drive a stirring element (30) arranged at least partly in the interior of the mixing container. The stirring element is used to mix the fluid and/or solid arranged in the mixing container. A drive-side shaft end (51) of the drive shaft couples the drive shaft to a drive (120) arranged outside of the mixing container. An adjustable seal (70) seals off the feed-through passage. A setting apparatus (80) is provided to switch the adjustable seal into at least two sealing operation states having different sealing effects.
