Indicator paper, Duotest
Roll length 5 m, 10 mm width. With two colour zones. Plastic box with 1 roll of indicator paper and colour scale. Duotest indicator papers combine two different indicator zones on a single strip. The zones are separated by a hydrophobic barrier, which effectively prevents mixing of the reaction colors, simplifying and precisely assigning the pH value.
Indicator papers without colour scale
Simple, completely impregnated indicator papers without colour scale. For orienting measurements and adjustments in different pH ranges.
LLG-Universal indicator paper, rolls
For the determination of pH values. Plastic dispensing reel with 1 roll of 5 m.
Special test papers
Most of our special test papers are semi-quantitative. They have a high-quality colour chart that allows quick and easy determination.
Test papers, lead acetate
The test paper allows the quick and easy detection of hydrogen sulphide. This gas occurs in the processing of raw oil. It is toxic even in low concentrations. Therefore, critical points are carefully checked. Sulphide containing solutions also give a positive reaction. Lead acetate is toxic and the test paper needs to be declared as hazardous. The technically equivalent Sulphide test paper is a non-toxic and safe alternative.
