eclipse-50The ECLIPSE 50 kit is a broad-range screening test designed for the qualitative detection of antibiotics in milk.

The method has been validated following the ISO 1369:2003(E) and is based on the inhibition of microbial growth. It is supplied in a microtiter plate format where each well contains agar medium spread with Geobacillus stearothermophilus.

When the plate is incubated at 65ºC spores germinate and cells grow producing acid and changing the agar pH. Variations of pH will produce changes of the agar colour from blue (purple) to yellowish. When milk samples contain inhibitors at higher concentrations than the detection limit, microorganisms will not grow and neither colour changes will be observed.
