pH indicator strips, colour bonded, Whatman™
Can be used for the rapid determination of pH values and has led to many applications in laboratories and industry.
- Instant pH readings
- Accurate for a wide range of routine pH testing
- Convenient and portable for field use
Individual plastic support strips carry four different segments of dye-impregnated indicator papers. The resulting combination of colour 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.
