COMET Incubator – Test Principle

ECLIPSE test is based on the growth inhibition of the Geobacillus stearothermophilus bacterium. In a specific culture medium and under suitable conditions, the spores of this bacterium germinate and multiply, acidifying the medium, producing a colour change in the culture medium from blue to yellow. If the milk sample contains an antimicrobial concentration higher than the test detection limit, the bacterial growth is inhibited and therefore the colour change of the medium will not occur.
