Product Overview
Basic Fuchsin LR is a synthetic rosaniline-based dye widely recognized for its intense magenta color and exceptional staining properties in laboratory settings. This LR-grade variant ensures moderate purity, making it suitable for general staining applications where high precision is not critical but reliability remains essential. The powdered form allows for easy dissolution in water or alcohol, enabling uniform staining solutions for histological and microbiological preparations. Its chemical stability under standard lab conditions ensures long shelf life when stored properly in airtight containers away from direct light and moisture. The dye’s affinity for acidic components in cellular structures makes it particularly effective in differential staining techniques, though its LR grade distinguishes it from analytical-reagent counterparts by balancing cost-efficiency with functional performance. Compatibility with common lab solvents and buffers further enhances its versatility, though users should verify specific protocol requirements for optimal concentration and pH adjustments. As a staple in educational and research labs, Basic Fuchsin LR serves as a foundational reagent for visualizing cellular and bacterial components with clarity.
FAQs
1. What is the difference between Basic Fuchsin LR and AR grades?
LR grade offers moderate purity suitable for routine lab work, while AR grade meets stricter analytical standards for research requiring higher precision and minimal impurities.
2. Can this dye be used for Gram staining procedures?
Basic Fuchsin is not typically used in Gram staining, which relies on crystal violet as the primary stain. However, it may serve in alternative staining protocols for specific bacterial structures.
3. How should Basic Fuchsin LR be stored to maintain stability?
Store in a cool, dry place in a tightly sealed container, protected from light and moisture to prevent degradation of the dye’s color intensity and staining efficacy.
4. Is this product compatible with ethanol-based solutions?
Yes, Basic Fuchsin LR dissolves readily in ethanol, making it suitable for alcohol-based staining solutions commonly used in histological preparations.
5. What safety precautions should be taken when handling this dye?
Wear gloves and protective eyewear, as Basic Fuchsin can cause skin and eye irritation. Work in a well-ventilated area to avoid inhaling fine particles during weighing or mixing.
