Gentian Violet, 1% Aqueous (also known as Crystal Violet) from LabChem Inc. is a high-purity biological stain and pH indicator. This water-based formulation is a cornerstone of microbiology, serving as the primary stain in the Gram stain procedure to differentiate Gram-positive bacteria. Because it is an aqueous solution, it is particularly useful for staining delicate biological samples where alcoholic solvents might cause unwanted dehydration or structural artifacts.

Description

Overview

Features:

Gram Stain Essential: Functions by infiltrating the peptidoglycan layer of bacterial cell walls, forming a deep purple complex that identifies Gram-positive organisms.
Gentle Staining: The aqueous matrix prevents the rapid cell shrinkage and dehydration associated with alcohol-based Gentian Violet stains.
pH Sensitivity: Acts as a pH indicator, transitioning from green/yellow at highly acidic levels (pH 0.0) to blue/violet as the pH increases (pH 2.0).
Microbiological Utility: Beyond staining, it can be used as a selective agent in culture media to inhibit the growth of most Gram-positive bacteria while allowing Gram-negatives to thrive.

Safety & Regulatory Information:

WARNING! Potential Health Hazard: Gentian Violet is a powerful dye and a suspected carcinogen (classified under CA Prop 65). It can cause serious eye irritation and is toxic to aquatic life.

Personal Protection: Wear nitrile gloves, a lab coat, and splash goggles. Gentian Violet will cause persistent purple staining on skin, clothing, and laboratory surfaces.
Stain Removal: If skin contact occurs, wash immediately with soap and water. Persistent stains can often be lightened with a 70% isopropyl alcohol wipe or a very dilute bleach solution, followed by thorough rinsing.
Storage: Store at room temperature (15°C to 30°C) in a tightly closed container. Protect from direct sunlight and keep away from strong oxidizing agents.
