Method and apparatus for monitoring biofilm formation

摘要

This invention relates to an apparatus ( 10 ) for monitoring biofilm formation on a surface ( 12 ). The apparatus ( 10 ) comprises a disk-shaped member ( 14 ) which provides said surface ( 12 ); and a sensor ( 16 ) for measuring biofilm formation on a measuring zone ( 18 ) of the surface ( 12 ). A plurality of bodies ( 29 ) are mounted on the surface ( 12 ) of the disk-shaped member ( 14 ) so that biofilm formation on different materials can be observed. The apparatus ( 10 ) includes a housing ( 22 ) wherein the member ( 14 ) is located. A body of liquid ( 24 ), such as water, is disposed inside the housing ( 22 ) and fills the housing ( 22 ) only partly. The member ( 14 ) is continuously moved into and out of the liquid ( 24 ) by being rotated about its central axis ( 30 ).
