pH-Fix

pH-Fix is a high quality, color-fixed pH test strip. For many years it has been very popular among professional analysts as well as chemical laymen.

Benefits:

Long handle
It prevents fingers from coming into contact with the sample. This adds handling convenience and increases safety of operation.
Color-fixed reactive pads
To prevent bleeding, the pH-indicator is chemically bound to the cellulose fiber. This effectively protects the sample against contamination and enables measurements even in weakly buffered or strongly alkaline solutions.
Brilliant color chart
Four different color blocks for each pH-value (pH-Fix 0-14) enable highly precise pH-determination and make the application rapid and reliable.

PEHANON® - pH measurement in coloured samples

PEHANON® - pH measurement in coloured samples ® PEHANON is a special pH-test strips that unifies the pH-indicator and the reference colors on one strip and has the following advantages:
Any sample color has the same effect on both, the reference colors and the reactive pad. This ensures unadulterated readings in colored solutions. The user can be sure to get accurate pH-values.
An invisible hydrophobic barrier just above the top color field prevents capillary action of the test solution beyond. The handle will remain dry and clean whatever the sample is. Therefore the use of the strip is very safe.
pH-values can be determined without a separate color chart. Workers and machinists can use single strips instead of complete packs with color chart which makes ® PEHANON highly economic.
