The NF-TVC vial is a general screening for total viable count and can be used for specification monitoring or sterility testing in food, nutraceutical and personal care/cosmetic products. The vial has broad inclusivity and an assay time of 22 hours for most applications. As organisms 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.
