Key Benefits
The BD 261190 Ferric Chloride Dropper Reagent offers superior accuracy, consistency, and ease of use for microbiological identification. Each single-use dropper ensures precise reagent volume and prevents cross-contamination. The reagents standardized 0.1N concentration guarantees consistent color development and reaction sensitivity, reducing interpretation errors. Its stable formulation provides a long shelf life and reliable results for routine biochemical and diagnostic testing, making it ideal for clinical, pharmaceutical, and teaching laboratories.
Compatibility and Applications
This reagent is specifically designed for use in the phenylalanine deaminase test, where it detects phenylpyruvic acid produced by enzymatic activity. When applied to inoculated phenylalanine agar, a positive reaction is indicated by the formation of a green color due to ferric ion complexation. The BD 261190 reagent is compatible with standard microbiological media and identification systems and is routinely used in clinical microbiology for differentiating Enterobacteriaceae, especially Proteus, Providencia, and Morganella species. It can also be used in educational and research settings for teaching biochemical differentiation.
Usage Guidelines
After incubation of the phenylalanine agar slant at 3537C for 1824 hours, add 45 drops of BD BBL Ferric Chloride Reagent directly to the slant surface. A green color appearing within 15 minutes indicates a positive test. No color change or a yellow result indicates a negative reaction. Use each dropper vial once to maintain sterility and reagent integrity. Store the reagent at 28C and protect from light to prevent degradation. Do not freeze or expose to high temperatures.
Certifications, Safety Standards, and Regulatory Approvals
The BD 261190 Ferric Chloride Dropper Reagent is manufactured in ISO 13485 and ISO 9001 certified facilities under Good Manufacturing Practice (GMP) standards. It complies with FDA and CE regulatory requirements for in vitro diagnostic (IVD) reagents. Each lot is quality-controlled for concentration accuracy, stability, and reactivity to ensure compliance with CLSI and USP microbiological testing standards.
Comparison with Competitor Products
Compared to generic biochemical reagents, BDs BBL Ferric Chloride Dropper Reagent offers unmatched precision, stability, and user convenience. Competitor reagents often require manual dilution or pipetting, increasing the risk of contamination and variability. BDs prefilled, sealed droppers eliminate preparation steps and provide standardized reagent delivery. Its superior shelf stability and consistent color reaction make it a preferred choice for laboratories performing routine biochemical identification and quality control.
Typical User Profile and Application Scenarios
The BD 261190 Ferric Chloride Dropper Reagent is used by clinical microbiologists, laboratory technologists, and research scientists in diagnostic, educational, and industrial laboratories. It is particularly useful in hospital microbiology labs for differentiating Enterobacteriaceae species, verifying phenylalanine deaminase activity, and confirming biochemical reactions in bacterial identification systems. Academic and pharmaceutical labs also use it for teaching and training purposes in microbial physiology and biochemical differentiation.
Best Practices for Use and Maintenance
Store the reagent at 28C, protected from direct sunlight and moisture. Always use fresh, unopened droppers to avoid contamination or reagent degradation. Shake gently before use if any sediment is observed. Discard dropper vials immediately after application. Avoid skin or eye contact; in case of accidental exposure, rinse thoroughly with water. Follow all biosafety and chemical safety procedures when handling reagents and microbial cultures.
Regulatory and Safety Information
The BD 261190 Ferric Chloride Reagent is intended for in vitro diagnostic use only and must be handled by trained laboratory personnel. It is classified as non-toxic when used as directed but may cause irritation upon contact. Always wear appropriate personal protective equipment (PPE), including gloves, lab coats, and protective eyewear. Dispose of used droppers and culture materials according to institutional biohazard and chemical waste disposal guidelines.
