FAQs

What is bromocresol purple indicator 0.04% (w/v) used for?

Bromocresol purple indicator 0.04% (w/v) is commonly used in laboratory applications for pH determination, analytical chemistry, and biochemical testing. It is especially useful for monitoring pH changes in the acidic to neutral range, providing a clear visual indication during titrations and reaction analysis.

What does a 0.04% (w/v) concentration mean?

A 0.04% (w/v) concentration means the solution contains 0.04 grams of bromocresol purple per 100 milliliters of solution. This standardized concentration ensures consistent color intensity and reliable pH response, supporting reproducible results across laboratory and analytical procedures.

What color change does bromocresol purple provide?

Bromocresol purple transitions from yellow at approximately pH 5.2 to purple at higher pH levels. This distinct color shift allows users to easily detect pH changes within the working range, improving accuracy and visibility during titrations, assays, and routine laboratory testing.

How is this indicator supplied and packaged?

This indicator is supplied as a ready-to-use liquid solution in a 125 mL poly bottle. The liquid format eliminates preparation steps, supports accurate dispensing, and reduces contamination risk, making it convenient for routine laboratory workflows and repeated analytical use.

What documentation and handling guidance are included?

The product is supplied with a Safety Data Sheet outlining hazard information, handling instructions, and regulatory considerations. This documentation supports safe use, proper storage, and compliance with laboratory safety standards in research, analytical, and educational environments.
