Soleris® Direct Pseudomonas Vial

The Direct Pseudomonas Vial (PD-109) is a screening vial for the detection of Pseudomonas species. The Direct Pseudomonas Vial (PD-109) with the addition of the supplement (S2-PSI) is specific for the detection of Pseudomonas aeruginosa. The vial has an assay time of 20 hours for most applications. This vial utilizes CO2 for detection. The vial contains a selective medium and an antibiotic supplement is added to the vial. 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 serves as a barrier, eliminating product interference with the reading window.
