Agar Bacteriological (Agar No.1) 500g, Oxoid
Login to see pricesBrand:
Thermo ScientificTM OxoidTM
Agar Bacteriological (Agar No. 1, Oxoid) is a clear purified high gel strength bacteriological agar compatible with all culture media. This agar has low calcium (Ca) and magnesium (Mg) levels and has very high working gel strength (1.5% w/v).
Agar Bacteriological, Oxoid is compatible with all culture media. It can be formulated to either broth or agar of the same medium with very similar metal values. This characteristic is especially valuable in antimicrobial MIC studies where differences in mineral/metal content can profoundly influence the results. Due to the low mineral/metal content in Agar Bacteriological, Oxoid, it allows free diffusion of antimicrobial substances. As a result, it is a highly satisfactory agar for antimicrobial diffusion studies (disc diffusion susceptibility tests).
