2. Consistency and Accuracy: Minimizes variability in disc diffusion tests for reproducible results.
3. Visual Interpretation: Facilitates detection of inoculum density, contamination, resistant mutants, beta-lactamase activity, and antibiotic interactions.
4. Flexibility: Supports a wide range of antibiotics and concentrations, adjustable to specific testing needs.
5. Durable and Reliable: Designed for consistent performance in demanding laboratory environments.

Disc Diffusion Method Advantages

• Comprehensive Results: Categorizes organisms into resistant, intermediate, and sensitive groups.
• Visual Insights: Provides a clear visual indication of critical factors such as contamination or beta-lactamase activity.
• Flexibility: Easily adaptable for testing various antibiotics and concentrations.

Usage Instructions

1. Preparation:
   • Load the dispenser with Oxoid Antimicrobial Susceptibility Discs (6 or 8 cartridges based on dispenser model).
   • Place a prepared 90mm media plate on the platform.
2. Dispensing:
   • Adjust the height of the dispenser as needed for even placement.
   • Activate the self-tamping mechanism to apply discs uniformly onto the media surface.
3. Incubation:
   • Incubate the plate under appropriate conditions based on the target organism and antibiotic.
4. Interpretation:
   • Measure zone diameters around the discs to evaluate bacterial susceptibility.

Storage and Maintenance

• Storage: Keep the dispenser in a clean and dry area when not in use.
• Cleaning: Clean thoroughly after each use to prevent contamination or damage.
• Maintenance: Regularly check the mechanism for wear and ensure proper alignment of disc cartridges.
