The direct yeast and mold vial allows for a rapid detection of yeast and mold in a wide variety of food, nutraceutical and personal care/cosmetic products. The vial has broad inclusivity and an assay time of 48-72 hours for most applications. As yeast and molds grow in the broth medium, the carbon dioxide (CO2) produced diffuses through a membrane layer into a soft agar plug containing a dye indicator. The color change in the dye is read by the instrument. The membrane layer in the vial servers as a barrier, eliminating product interference with the reading window. Chloramphenicol, which is used for vial selectivity, is contained in the vial (rather than a separate supplement) to minimize end user exposure. The membrane layer in the vial serves as a barrier, eliminating product interference with the reading window.
