BD 231544 - Sensi-Disc Rifampin 5mcg Antimicrobial Susceptibility Testing Disc

BD 231544 - Sensi-Disc Rifampin 5mcg Antimicrobial Susceptibility Testing Disc

The BD 231544 Sensi-Disc Rifampin 5mcg is a high-quality antimicrobial susceptibility testing (AST) disc used to evaluate bacterial sensitivity to rifampin. Manufactured under BDs strict quality controls, each disc delivers a precise 5mcg dose of rifampin to ensure consistent diffusion and accurate zone-of-inhibition results. This product is widely used in clinical microbiology laboratories for routine susceptibility testing of organisms where rifampin is a relevant therapeutic agent.

Key Benefits

The rifampin 5mcg Sensi-Disc provides uniform antibiotic potency and consistent diffusion characteristics, supporting reliable AST results. BDs advanced manufacturing process reduces disc-to-disc variability and ensures stable antibiotic activity throughout the shelf life. The cartridge-style packaging protects discs from moisture, environmental exposure, and contamination, ensuring optimal performance during testing.

Compatibility and Applications

BD Sensi-Disc Rifampin discs are compatible with:

• Mueller Hinton agar and other approved AST media
• Standard Kirby-Bauer disc diffusion methods
• BD Sensi-Disc dispensers for fast and accurate placement

They are used primarily to assess susceptibility in organisms including Staphylococcus aureus, Neisseria meningitidis, and other pathogens where rifampin plays a role in treatment or prophylaxis.

Usage Guidelines

Prepare a standardized inoculum and apply it evenly to a Mueller Hinton agar plate. Using a sterile forceps or BD disc dispenser, place the rifampin 5mcg disc onto the agar surface. Incubate the plate as recommended by CLSI or EUCAST guidelines. Measure inhibition zones and interpret results according to the most current AST standards. Keep discs sealed when not in use and allow cartridges to reach room temperature before opening.

Certifications, Safety Standards, and Regulatory Approvals

This product is manufactured under ISO 9001 and ISO 13485 certified quality systems. It meets FDA and CE requirements for in vitro diagnostic (IVD) use. Each production lot undergoes rigorous testing for antibiotic potency, diffusion accuracy, pH stability, and expected performance using certified control organisms.

Comparison with Competitor Products

Compared with generic rifampin discs, BD Sensi-Discs provide more precise dosing, reduced batch variability, and more reliable inhibition patterns. Competitor discs often show inconsistent potency or degradation over time, which can affect AST accuracy. BDs protective cartridge packaging offers added assurance against moisture loss and contamination, further improving reliability.

Typical User Profile and Application Scenarios

This disc is commonly used by:

• Hospital and clinical microbiology labs
• Public health and reference laboratories
• Academic institutions conducting antimicrobial resistance studies
• Diagnostic laboratories performing routine Kirby-Bauer susceptibility testing

Best Practices for Use and Maintenance

Store cartridges tightly sealed at recommended temperatures to maintain potency. Avoid exposing discs to moisture or excessive heat. Use clean, dry dispensing tools and return the cartridge cap immediately after removing discs. Verify performance with routine QC testing using approved control strains. Dispose of used discs and plates according to biohazard guidelines.

Regulatory and Safety Information

For in vitro diagnostic use only. Handle all bacterial isolates under biosafety level 2 conditions. Wear appropriate PPE, and follow facility protocols for disposal of culture materials and testing components.
