The convenience of using HiIndicator papers for the rapid determination of pH values has led to
many applications in laboratories and industry. These pH papers are made with special indicator
dyes that change color at specified pH value.

Somewhat uneven colour of the strips is of no consequence. The colour obtained on use is
indicative of the correct pH.

Application : Analytical chemistry, biology & various laboratories and industries etc.

Direction for use : Tear off strip of indicator paper and insert it for a few seconds into the
solution to be tested. With highly viscous or stained liquids and with suspensions, drip the
substance onto the indicator paper. Compare the wet paper with the colour scale. For papers
where liquids are dripped, compare the reverse side. Possible discolouration of the dry new
papers may be caused by their high sensitivity. This does not impair the efficacy of the Indicator
papers for pH determinations.

The so-called indicator error may occur with very weakly buffered or unbuffered solution and
can be compensated for up to a point in the following manner. : - The strip can be made to adhere
to the inner wall of the a test tube, which can then filled to the upper edge of the paper with the
fluid to be tested. After 1/2 to 1 minute, the colour of the paper may be compared with the scale
through the glass of test tube.
