General description
Blue and red litmus paper and phenophthalein strips are mixed-indicator tests designed for fast, accurate, and reliable pH solution testing.
Universal indicators
Cytiva′s acid-alkali litmus paper is impregnated with a mixture of pH indicators. They assume a color specific to sample pH upon contact with a sample. The convenience of using indicator papers for the rapid determination of pH values has a variety of applications in laboratories and industry.
These easy-to-use test papers facilitate a general test for acid or alkaline reactions. Change in color occurs around pH 5 to 8. Blue and red litmus paper reels are particularly recommended for educational use.
Phenophthalein reels
Phenophthalein white paper changes to pink at pH 8.3 and becomes red at pH 10. These pH indicator strips are useful for the determination of the neutralization point in weak acid/strong alkali reactions.
