Thermo Scientific™ Oxoid™ Cloxacillin CX Antimicrobial Susceptibility Disks

The Thermo Scientific™ Oxoid™ Cloxacillin Antimicrobial Susceptibility Disks are high-quality, easy-to-use paper disks designed for manual antimicrobial susceptibility testing (AST) using the disk diffusion (Kirby-Bauer) method. These disks are impregnated with 5 micrograms of cloxacillin, a penicillinase-resistant β-lactam antibiotic, and are primarily intended for veterinary diagnostic applications. They support reliable phenotypic determination of microbial susceptibility profiles, especially for β-lactamase-producing Gram-positive cocci such as Staphylococcus aureus.

Each disk is housed within a shatterproof, spring-loaded cartridge, with clearly labeled end indicators for ease of use, reducing the risk of contamination or error. The cartridges are individually sealed with a desiccant, ensuring long-term stability and potency by maintaining moisture levels below 2%.
