The Direct Lactic Acid (DLA) Vial detects lactic acid microorganism contamination in food products. When carbon dioxide (CO2) is released by growing lactic acid bacteria, the CO2 produced diffuses through a membrane layer into a soft agar plug containing a dye indicator. The colour change in the dye is read by the Soleris® instrument. The membrane layer also serves as a barrier, eliminating product interference with the reading frame.
