Duotest Indicator Papers

Impregnated indicator papers with greater accuracy and improved ease of reading. Two complimentary indicator zones on one strip – separated by a white centre band – guarantee clear colour diffentiation and a more accurate estimation of intermediate pH values. The white centre band is hydrophobic and prevents that colours of the two indicator zones run into one another.
