The Gram Negative Vial is a general screening vial for gram negative organisms in personal care and cosmetic products. The vial has an assay time of 24 hours for most applications. The vial uses a selective media and antibiotic supplement. As organisms grow in the broth medium, the carbon dioxide (CO2) produced diffuses through a membrane layer in to a soft agar plug containing a dye indicator. The membrane layer also serves as a barrier, eliminating product interference within the reading window. The color change in the dye is read by the instrument
