Antibiotic susceptibility discs (AST discs) from Liofilchem, distributed by Kormay across Canada, for standardized disc diffusion testing (Kirby-Bauer method) in clinical microbiology, veterinary diagnostics, and pharmaceutical quality control labs. Each disc delivers a fixed antimicrobial concentration onto inoculated agar to determine bacterial susceptibility or resistance.
- Single-antibiotic and combination discs across major antimicrobial classes (beta-lactams, aminoglycosides, tetracyclines, macrolides, glycopeptides, and more)
- Supplied in cartridges of 50 discs for use with standard disc dispensers
- Includes newer agents (e.g. cefiderocol, eravacycline, omadacycline) alongside established antibiotics
- Suited to CLSI/EUCAST-based susceptibility testing workflows
Search by antibiotic name or abbreviation below, or contact Kormay to build a custom AST panel for your lab's testing protocol.
