Duotest and Tritest pH Indicator Papers
Duotest indicator papers feature two reactive zones on the same strip, separated by a hydrophobic barrier that prevents the indicator reagents from mixing, while also providing greater mechanical stability.
Tritest indicator papers feature three reactive zones on the same strip, ensuring optimal color differentiation and secure reading of intermediate values. Tritest papers are designed for pH readings from 1 to 11 in 1-unit intervals. The Tritest L indicator paper also includes two hydrophobic barriers to separate the reactive zones. This ensures that the indicator reagents do not mix, even in strongly alkaline solutions, guaranteeing accurate readings.
The combination of different indicator reagents in a single paper allows for more accurate differentiation between different values, facilitating correct pH reading.
