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).

Oxoid Agar Technical (Agar No. 3) is a technical grade, high working gel strength agar (1.2% w/v) suitable for purposes where clarity and compatibility are not of prime importance or where the high mineral/metal content has cultural advantages.
