BD 231660 - Sensi-Disc Ampicillin/Sulbactam 10g Antibiotic Susceptibility Testing Disc, 10/BX
The BD 231660 Sensi-Disc Ampicillin/Sulbactam 10g is a high-precision antimicrobial susceptibility testing (AST) disc used in the standardized Kirby-Bauer disk diffusion method. Manufactured by BD (Becton Dickinson), this product is designed to evaluate bacterial susceptibility to the synergistic antibiotic combination of ampicillin and sulbactam. Each disc contains 10g of the combined agents (2:1 ratio), allowing for the accurate detection of beta-lactamaseproducing organisms and assessment of resistance mechanisms. The discs are packaged in moisture-resistant cartridges to ensure stability, potency, and reliability for consistent results in clinical and research microbiology laboratories.

Key Benefits
The BD Sensi-Disc Ampicillin/Sulbactam 10g offers exceptional accuracy and reproducibility for antimicrobial susceptibility testing. Its precisely controlled antibiotic concentration ensures standardized diffusion and clear inhibition zones. Each batch undergoes rigorous quality testing to meet CLSI (Clinical and Laboratory Standards Institute) performance criteria for potency, uniformity, and sterility. The inclusion of sulbactam, a potent beta-lactamase inhibitor, enhances the efficacy of ampicillin by overcoming enzymatic resistance, providing clinicians with reliable data for selecting effective therapeutic options. BDs superior quality control ensures optimal shelf life and consistent results across all test runs.
Compatibility and Applications
This Sensi-Disc is designed for use in the Kirby-Bauer disk diffusion testing procedure on Mueller-Hinton Agar (MHA) plates. It is suitable for use in hospital, clinical, pharmaceutical, and research laboratories for evaluating the susceptibility of Gram-negative and Gram-positive organisms to ampicillin/sulbactam. The BD 231660 is particularly effective for testing members of the Enterobacteriaceae family, as well as Haemophilus spp., Neisseria spp., and Staphylococcus spp. The discs are compatible with BD Sensi-Disc dispensers, ensuring convenient handling and precise placement on agar plates for consistent results.
Usage Guidelines
Prepare a 0.5 McFarland bacterial suspension and inoculate a Mueller-Hinton Agar plate uniformly using a sterile swab. Using sterile forceps or a BD Sensi-Disc dispenser, place one BD 231660 Ampicillin/Sulbactam 10g disc on the inoculated agar surface. Incubate the plate in an inverted position at 352C for 1618 hours under aerobic conditions. After incubation, measure the diameter of the inhibition zone around the disc in millimeters and interpret results according to current CLSI or EUCAST breakpoints. Dispose of all materials according to institutional biosafety and hazardous waste disposal policies.
Certifications, Safety Standards, and Regulatory Approvals
The BD 231660 Sensi-Disc Ampicillin/Sulbactam 10g is manufactured in ISO 13485certified facilities following Good Manufacturing Practices (GMP). It is FDA-cleared and CE-marked for in vitro diagnostic (IVD) use. Each lot undergoes stringent quality control testing for potency, stability, sterility, and diffusion uniformity. The discs are traceable to recognized international standards to ensure compliance with CLSI and EUCAST methodologies. BDs production and packaging processes guarantee consistent performance and long-term storage stability under recommended conditions.
Comparison with Competitor Products
Compared to other antibiotic discs, BD Sensi-Discs are recognized for their superior consistency, precision, and durability. Competitor discs may exhibit variability in antibiotic concentration, resulting in inconsistent diffusion zones. BDs proprietary disc manufacturing and packaging technology minimizes potency loss and ensures accurate diffusion characteristics. The inclusion of a moisture-resistant cartridge provides extended shelf life and reliable storage. Laboratories worldwide choose BD Sensi-Discs for their proven reproducibility and compliance with international AST standards.
Typical User Profile and Application Scenarios
This product is used by clinical microbiologists, laboratory technologists, and researchers involved in antimicrobial resistance testing and epidemiological studies. It is essential in hospital microbiology labs for guiding empiric therapy and infection control, as well as in research and pharmaceutical quality control for monitoring antibiotic efficacy. The BD 231660 Sensi-Disc is also valuable in public health institutions performing surveillance of antibiotic resistance trends and beta-lactamasemediated resistance mechanisms.
Best Practices for Use and Maintenance
Store the discs at 28C in their original, sealed moisture-protective packaging. Before opening, allow the discs to equilibrate to room temperature (2025C) to prevent condensation. Use aseptic technique during handling and placement. Avoid prolonged exposure to air or humidity, as this may reduce disc potency. Always use fresh, quality-controlled Mueller-Hinton Agar plates and standardized inoculum densities for accurate results. Regularly check the expiration date and discard any expired discs. Maintain records of quality control performance using reference strains recommended by CLSI, such as Escherichia coli ATCC 25922.
Regulatory and Safety Information
This product is intended for professional laboratory use only. All microbial isolates should be handled as potentially infectious materials under Biosafety Level 2 (BSL-2) precautions. Personnel must wear appropriate personal protective equipment (PPE), including gloves, laboratory coats, and eye protection. Decontaminate all used materials through autoclaving or incineration before disposal. Refer to the products Safety Data Sheet (SDS) for detailed handling, storage, and disposal information. BD ensures that all Sensi-Disc products comply with global safety, quality, and environmental regulations for diagnostic microbiology.
