Methyl Orange works as pH indicator and finds suitability in titrations as it provides for changing color at pH of mid-strength. We can offer it in tamper proof finish in both standard as well as customized packaging support that meets the industrial standards.

Applications :
Used in –

• Dyeing industry
• Printing textiles industry

Methyl Red is used for conducting mixed-acid fermentation where it contains peptone, glucose, and phosphate buffer. It also produces desired acid for overcoming buffering capacity of broth that causes decrease in pH results. Further, organisms perform other types of fermentation also cannot overcome buffering capacity of broth.

Applications :
Suitable for conduction tests involving –

• Indole
• Methyl-Red

A pH indicator is a halochromic chemical compound that is added in small amounts to a solution so that the pH (acidity or basicity) of the solution can be determined visually. 

Alkali Blue is a synthetic dye used as a biological stain and analytical indicator. It produces a blue coloration and is commonly used for staining cells, tissues, and certain biological structures, providing clear contrast for microscopic observation. 

Azure A is a cationic (basic) thiazine dye, structurally related to methylene blue. It is widely used in histology, cytology, hematology, and microbiology as a stain and pH indicator. Azure A has high affinity for acidic components of cells, such as nucleic acids and mast cell granules.

Methyl Red is a widely used azo dye that functions as both a pH indicator and a biological stain. It is especially known for its role in acid-base titrations and in microbiology for the Methyl Red (MR) test to identify bacterial fermentation pathways. Its sharp and distinct color transition makes it one of the most reliable weak acid indicators.

Thymolphthalein is a phthalein dye used as an acid-base (pH) indicator. When it is designated as "ACS Grade," it means the chemical meets the stringent specifications set by the American Chemical Society (ACS) for use in analytical and research laboratories. This ensures a high level of purity and consistency.

Phenol Red Sodium Salt (the sodium salt of phenolsulfonphthalein) is a widely used acid–base indicator and pH-sensitive dye. The sodium salt form enhances water solubility, making it highly suitable for biological, clinical, and analytical applications. It is especially popular in cell culture media and diagnostic assays because of its distinct color transitions in the physiological pH range.
