Eclipse 3G test kit – 96 tests


In stock

ECLIPSE is a qualitative test, supplied in a flexible and handily format, for detection of antibiotics and inhibitors in raw, heated or powder milk from cow, sheep or goat. The ECLIPSE test kit contains 96 individual tests microtiter plate. Each well contains growth medium spread.


ECLIPSE is a test 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 spores and a pH indicator.

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.

ECLIPSE 3G tests are used with dry incubator Milkotester ET- W24. ECLIPSE 3G detects inhibitors from most used groups of antibiotics in animal husbandry – β-lactam, tetracycline, sulfamides, macrolides, aminoglycosides, lincosamides and others.
