pH Indicators 0-14 6x80 mm
The convenience of using indicator papers for the rapid determination of pH values has led to many applications in laboratories and industry.
Strips type CF (color bonded dye system)
Individual plastic support strips carry four different segments of dye-impregnated indicator papers. The resulting combination of color differences gives an extremely clear and accurate visual pH value. All the dyes are chemically bonded to the paper and cannot be leached into solution; problems associated with contamination of the sample and resultant anomalous readings are avoided.
Strips type CS (integral comparison chart)
Each test strip has a central segment of indicator dye and, printed alongside, eight or more different color segments marked with corresponding pH values for matching purposes.
The pH test value can be read off by direct comparison of the test strip color and the color bars. Excellent for colored solutions, when any changes in the color of the paper stock are automatically canceled out.
Dispensers type TC (triple color band)
The strip has three separate indicator dye, color bands. The individual combination of color change resulting from each test is compared with the color-coded comparison chart printed on the dispenser, giving improved speed and accuracy in reading.
Dispensers type SR (standard range)
A full range and some narrow ranges in this popular pH indicator dispenser.
The book format is particularly suitable for educational and industrial use.
In schools, they are economical because the amount of paper per student can be carefully controlled.
