Description

Lactophenol Cotton Blue is a vital histological and microbiological staining solution, specifically formulated for the visualization of fungal elements and other biological structures. Its primary value lies in its ability to provide clear, high-contrast differentiation of cell walls and chitinous components against a stained background, which is critical for accurate microscopic analysis. This product is essential for professionals in clinical diagnostics, mycology research, and industrial quality control laboratories who require reliable and consistent staining performance for identification and enumeration purposes.

Application

• Fungal Identification in Clinical Mycology: Standard staining agent for direct microscopic examination of skin, hair, nail scrapings, and tissue samples to diagnose dermatophyte and other fungal infections.
• Environmental and Food Safety Monitoring: Used in the analysis of air, surface, and product samples for the presence of mold and yeast contaminants.
• Research and Academic Laboratories: A fundamental tool for studying fungal morphology, life cycles, and taxonomy in pure culture.
• Veterinary Diagnostics: Employed in the examination of animal specimens for fungal pathogens.
• Pharmaceutical and Cosmetic Quality Control: Part of microbial limit testing protocols to detect and identify fungal contamination in raw materials and finished products.
• Preparation of Permanent Microscopic Slides: The lactophenol component acts as a clearing agent and mounting medium, preserving fungal structures for long-term observation.

Quality Control

Our Lactophenol Cotton Blue is manufactured under controlled conditions to ensure batch-to-batch consistency and performance reliability for diagnostic and research applications. Each lot is tested for critical parameters including staining intensity, pH, and clarity to meet in-house specifications designed for optimal microscopic results. A Certificate of Analysis (COA) detailing these quality attributes is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store at room temperature (15-25°C) in a cool, dry, and well-ventilated area. Keep away from strong alkalis and incompatible organic solvents. The solution is light-sensitive; prolonged exposure to light may degrade the staining properties.
