Strength: 540% Extra Pure
Basic Violet 10, widely known as Rhodamine B, is a brilliant, high-strength cationic dye. It is famous for its unique visual property: the powder appears as shimmering green crystals, but when dissolved in water, it produces an intensely bright, fluorescent pink/violet solution.
Ruvon's Rhodamine B 540% is the highest commercial strength available. It offers exceptional cost-efficiency because even a tiny amount creates a vivid color. It is primarily used in applications where brightness and visibility are paramount, such as paper dyeing, fluorescent pigments, and safety markers.
Guaranteed 540% concentration for maximum color yield.

Rhodamine B exhibits a physical phenomenon called Solid State Metallic Luster. The crystals absorb light in such a way that they reflect a metallic green sheen. However, when dissolved:
Used to dye crepe paper, tissue paper, and file covers where bright pink/red shades are needed.
The primary dye used to give mosquito repellent coils their distinct red/pink color.
Used in ballpoint pen inks, stamp pads, and bright fluorescent highlighters.
Used as a tracer dye in water systems, sewage lines, and industrial pipes to find leaks.
Dyeing of wool, silk, and acrylic fibers. (Less common for cotton due to poor light fastness).
Used to manufacture "Phosphotungstic Acid" (PTA) lakes for pink pigments.
Standard packing. Strong drums prevent crystal breakage and leakage.
Corrosion-free option for export markets.
Rhodamine B is a potent chemical dye.
Premium 540% Strength. The gold standard for Paper and Mosquito Coils.
