pH-FIX TEST STRIPS, NON-BLEEDING
Features

• In contrast to conventional pH papers, the indicator dyes of pH-Fix strips are substantially bound to the cellulose fibres, therefore colour-bleeding, even in strongly basic solutions, is avoided.
• Measurement of pH value is possible even in unbuffered or very weakly buffered solutions, since the sticks can be left in the solution until the final colour change is completed.
• Test samples are not contaminated by the indicator dyes.
• Colours of the individual colour fields cannot run into each other, allowing for a more precise comparison with the colour scale.
• Recently developed indicator dyes guarantee a sharp differentiation between the individual pH values and a clear and easy comparison to the colour scale.
• Four different pH papers measuring 6 x 5mm, are bonded onto a 6 x 85mm plastic strip. The strips are sufficiently long to avoid contact between the fingers and the test sample.

PEHANON® pH TEST STRIPS
For coloured solutions and suspensions.
Features

• The indicator and colour scale are combined on a single pH paper strip for fast, convenient and accurate reading of pH value.
• No need to compare colour against a separate scale.
• Allows pH measurement of coloured solutions and suspensions, since the colour of the test solution acts on the comparison scale in the same manner as on the indicator field.
• The PEHANON® series covers the entire pH range from 0 to 12, with one universal strip and 13 narrow ranges which overlap, giving a comprehensive choice to suit every application.
• The indicator zone (unprinted field) is in the centre of the strip, the comparison fields above and below same. The strip is submerged in the solution for about three seconds so that all colour zones are wetted. The centre field changes colour according to the pH value of the solution and is then compared against the colour field bearing the corresponding pH value imprint.
• An invisible hydrophobic barrier just above the top colour field prevents capillary action of the test solution beyond that point, so corrosive, toxic or otherwise noxious liquids do not come in contact with fingers.
• Dimensions 11 x 100mm, pk/200.
