HardyDisks™ Bacitracin 0.04 U Antimicrobial Susceptibility Test Discs

This cartridge contains 50 HardyDisks™ bacitracin differentiation discs designed for reliable antimicrobial susceptibility testing in clinical laboratory settings. Each disc contains approximately 0.04 units of bacitracin for precise microbial identification.

Professional Laboratory Testing Solution

Each cartridge features a spring-loaded metal disc dispenser that ensures smooth and reliable dispensing during testing procedures. This design minimizes handling time and maintains disc integrity throughout the testing process.

Manufactured to meet professional laboratory standards, these discs provide consistent performance for accurate microbial identification. Proper storage and handling ensure optimal results throughout the product's shelf life.
