Malachite Green Extra Pure is a synthetic dye of exceptional purity, recognized for its intense green coloration and versatile laboratory uses. It is commonly used as a biological stain, especially in microbiology for identifying and differentiating bacterial species, and in histology for staining cell structures. Additionally, Malachite Green serves as an effective fungicide and antiparasitic agent in aquaculture and laboratory testing. Its high purity ensures reliable performance in analytical applications, including redox titrations and as a pH indicator in specific chemical reactions. Its vivid color and chemical stability make it a valuable reagent in both teaching and professional research settings.
Malachite Green Extra Pure
Primary Uses
- Biological Stain:
- Widely used as a histological stain in microscopy for staining bacterial spores, fungi, and cytoplasmic structures.
- Microbiological Identification:
- Functions as a selective dye in culture media (e.g., Lowenstein–Jensen medium for Mycobacterium tuberculosis).
Secondary Uses
- Aquatic Pathogen Studies:
- Utilized in research for controlling fungal and protozoan infections in fish, though its use is regulated.
- Indicator Dye:
- Occasionally used as a pH or redox indicator in certain specialized chemical tests.
- Demonstration of Dye Adsorption:
- Used in educational experiments to study adsorption, dye uptake by tissues, or dye removal from water.
