Universal indicator paper Tritest L
For determination of pH value.
Roll length 5 m, 14 mm width. With 3 colour zones and 2 hydrophobic zones. The zones are separated by a hydrophobic barrier, which effectively prevents mixing of the reaction colours and increases mechanical stability.
Plastic container with 1 roll of indicator paper and colour scale....
