My Experiments 
The Thermo Scientific™ Oxoid™ Tobramycin Antimicrobial Susceptibility Discs are precision-manufactured paper discs used for the in vitro determination of bacterial susceptibility to tobramycin via the disc diffusion method (Kirby-Bauer). Tobramycin, an aminoglycoside antibiotic, is commonly used to treat Gram-negative infections including those caused by Pseudomonas aeruginosa, Escherichia coli, and Klebsiella species.
Each 6 mm disc is pre-impregnated with either 10 µg or 30 µg of tobramycin and delivered in robust spring-loaded cartridges designed for accuracy, ease of use, and compatibility with disc dispensers. The discs are individually sealed in foil blister packs with desiccant to maintain a moisture level of less than 2%, ensuring extended shelf life and performance stability.
Key Features
- Available in 10 µg and 30 µg concentrations for testing flexibility
- Designed for AST using manual disc diffusion (Kirby-Bauer) methods
- Accurate and reproducible zone readings for clinical decision-making
- 6 mm paper discs sealed in spring-loaded, shatterproof cartridges
- Clear labeling and end-of-cartridge indicators for easy monitoring
- Complies with CLSI, EUCAST, BSAC, DIN, and SFM guidelines
- Desiccant-sealed cartridges ensure <2% moisture for long-term stability
- For in vitro diagnostic use only
Packaging Format
- 50 discs per cartridge
- 5 cartridges per pack (250 discs total)
- Supplied in individually sealed foil blister packs
