Description

Carbol-Fuchsin is a vital histological and microbiological stain, a compound of basic fuchsin and phenol. Its primary value lies in its unique staining properties, particularly for acid-fast organisms and fungal elements, making it indispensable for diagnostic and research purposes. This product is essential for laboratories in the pharmaceutical, clinical diagnostics, and life science research sectors, as well as for educational institutions.

Application

• Ziehl-Neelsen Staining: The primary application for the microscopic identification of acid-fast bacilli, most notably Mycobacterium tuberculosis.
• Fungal Staining: Used in procedures like Kinyoun's stain to visualize fungi, including Cryptococcus and Nocardia species.
• Histological Staining: Employed in tissue section staining to highlight specific cellular structures and microorganisms.
• Bacterial Spore Staining: A key component in staining protocols to differentiate bacterial spores from vegetative cells.
• Quality Control in Microbiology: Used as a reference stain in clinical and industrial microbiology laboratories to ensure staining protocol accuracy.
• Educational & Research Use: A fundamental reagent in university teaching labs and life science research for microbiology and histology studies.

Quality Control

Our Carbol-Fuchsin is manufactured and tested to meet the stringent requirements of diagnostic and research applications. Each batch undergoes rigorous quality testing to ensure consistent staining performance, purity, and composition. While not typically compendial (USP/EP), our quality system ensures reliability for critical laboratory use. Certificates of Analysis (COA) detailing batch-specific results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Keep away from strong acids and organic solvents. Ensure the container is kept upright to prevent leakage.
