Overview

Rose Bengal Powder is a synthetic xanthene-class dye widely used in microbiology, mycology, histology, and laboratory research. It is recognised for its strong staining properties and its ability to selectively influence microbial growth when incorporated into culture media under controlled laboratory conditions.

In microbiology, Rose Bengal is most commonly used as a selective dye component in fungal culture media, where it enhances visual contrast and helps suppress excessive bacterial growth, improving the isolation and enumeration of yeasts and moulds. Its intense coloration and reliable solubility also make it suitable for general laboratory staining and research workflows.

Ausamics Rose Bengal Powder is supplied as a high-purity laboratory-grade dye, offering consistent colour strength, solubility, and batch-to-batch performance.
