Product Overview

High-purity phenolphthalein indicator for acid-base titrations.

Detailed Description

Phenolphthalein Indicator supplier in Oman - Global Chemicals LLC provides high-quality phenolphthalein solution for analytical laboratories and educational facilities in Muscat, Sohar, Duqm, Salalah. Our phenolphthalein indicator changes from colorless (pH <8.2) to pink/magenta (pH >10) making it ideal for strong acid-strong base titrations. The 1% alcoholic solution is ready to use with just 2-3 drops per titration. Widely used in university chemistry labs, water testing facilities, pharmaceutical QC, and industrial analysis across Oman. Essential for teaching acid-base concepts and performing volumetric analysis. Phenolphthalein indicator solution (0.1% in ethanol or 1% in ethanol) is one of the most fundamental acid-base indicators used in Oman's teaching and industrial QC laboratories — the standard indicator for alkali titrations (strong acid vs strong alkali endpoint at pH 8.2–10.0). Used in caustic soda strength determination, cement alkalinity testing, acid-base titrations in food QC labs, carbonate/bicarbonate alkalinity analysis in water testing, and phenolphthalein alkalinity measurement per APHA Standard Methods. Global Chemicals LLC supplies phenolphthalein indicator in 0.1% ethanol solution (100mL, 500mL dropper bottles) and as powder/tablets for preparing fresh solutions. CoA and SDS available.
