Phenol Red
Phenol Red has several laboratory uses:
- pH Indicator: It is primarily used as a pH indicator in laboratory solutions. Its color change from yellow to red helps scientists and researchers determine the pH level of a solution visually.
- Cell Culture: In cell biology and microbiology, Phenol Red is often added to cell culture media to monitor pH changes. It helps maintain optimal pH conditions for cell growth and viability.
- Environmental Monitoring: It is used in environmental sciences to assess pH levels in water bodies and aquatic environments. Changes in its color indicate variations in pH, which can be critical for understanding environmental health.
- Medical Diagnostics: Phenol Red is also employed in medical diagnostics, particularly in urine tests. It can indicate changes in urinary pH, which may be indicative of certain health conditions or metabolic processes.
- Chemical Analysis: In chemical laboratories, Phenol Red can be used in titrations and other analytical techniques where pH monitoring is necessary for accurate results.
