BD 231641 - BBL Sensi-Disc Aztreonam 30mcg Precision Disk for Antimicrobial Susceptibility Testing, 10/BX

BD 231641 - BBL Sensi-Disc Aztreonam 30mcg Precision Disk for Antimicrobial Susceptibility Testing, 10/BX

The BD 231641 BBL Sensi-Disc Aztreonam 30mcg is a high-precision antimicrobial susceptibility testing (AST) reagent designed for standardized disk diffusion methods such as the Kirby-Bauer technique. Each sterile paper disk contains 30 micrograms of aztreonam, a monobactam antibiotic widely used for identifying susceptibility patterns in aerobic Gram-negative bacteria. Manufactured under BDs strict quality assurance system, these Sensi-Discs ensure consistent antibiotic diffusion profiles and reproducible inhibition zone results, supporting accurate clinical decision-making in microbiology laboratories.

Key Benefits

The BD 231641 Aztreonam 30mcg Sensi-Disc delivers reliable, reproducible performance for routine and complex AST workflows. Each disk provides a precise antibiotic concentration to ensure uniform diffusion, producing clear, interpretable zones of inhibition. The sterile, ready-to-use format reduces contamination risks and streamlines laboratory operations. With exceptional batch-to-batch consistency, these Sensi-Discs help clinicians identify effective therapies, support antibiotic stewardship initiatives, and enhance diagnostic accuracy.

Compatibility and Applications

BD 231641 Sensi-Discs are compatible with standard Mueller-Hinton agar and conform to CLSI (Clinical and Laboratory Standards Institute) and EUCAST (European Committee on Antimicrobial Susceptibility Testing) guidelines. They are used primarily to test Gram-negative bacteria including Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, and Enterobacter species. Aztreonam testing is particularly valuable for identifying beta-lactam resistance mechanisms and guiding therapy for infections involving multidrug-resistant Gram-negative organisms.

Usage Guidelines

Perform susceptibility testing following CLSI or EUCAST-approved protocols. Prepare a 0.5 McFarland bacterial suspension and evenly inoculate a Mueller-Hinton agar plate. Place the BD 231641 Aztreonam 30mcg disk onto the agar surface using sterile forceps or a disk dispenser. Incubate plates at 3537C for 1618 hours. Measure the inhibition zone diameter and interpret the result using the appropriate clinical breakpoints. Store disks at 28C in a dry environment and avoid exposure to heat or moisture.

Certifications, Safety Standards, and Regulatory Approvals

The BD 231641 Sensi-Disc is manufactured in ISO 9001 and ISO 13485 certified facilities and meets FDA and CE regulatory requirements for in vitro diagnostic use. Each lot undergoes strict quality checks for potency, diffusion uniformity, sterility, and stability in accordance with CLSI performance standards. BDs quality system ensures each disk delivers reliable, validated performance in clinical environments.

Comparison with Competitor Products

Compared to generic aztreonam disks, BD Sensi-Discs offer superior consistency, potency retention, and diffusion reliability. Competitors often show variability in antibiotic load or uneven drug distribution, causing inconsistent zone sizes. BDs proprietary manufacturing ensures uniform antibiotic impregnation, high stability, and predictable inhibition zone formation, making it a preferred tool for laboratories performing high-volume or precision-critical AST.

Typical User Profile and Application Scenarios

The BD 231641 disk is used by clinical microbiologists, laboratory technologists, infection-control specialists, and pharmaceutical researchers. Common use cases include routine AST panels, pathogen resistance profiling, outbreak investigations, and quality control testing in hospitals, public health labs, and research centers. Its reliability makes it essential for monitoring resistance trends involving Gram-negative bacteria.

Best Practices for Use and Maintenance

Use sterile forceps when handling disks and place them gently onto the agar surface to avoid embedding. Always allow refrigerated disks to reach room temperature before opening to prevent condensation. Use control strains such as Escherichia coli ATCC 25922 or Pseudomonas aeruginosa ATCC 27853 to verify performance. Discard expired or compromised disks, and dispose of used materials following institutional biosafety guidelines.

Regulatory and Safety Information

The BD 231641 Sensi-Disc is intended for in vitro diagnostic use by trained laboratory personnel. While the disk itself is non-hazardous, testing procedures involve live microorganisms that must be handled under biosafety level 2 conditions. Use appropriate PPE including gloves, lab coats, and protective eyewear. Follow all institutional, state, and federal regulations for disposal of microbiological waste.
