Non-bleeding indicator sticks for rapid reading of weakly buffered or strongly alkaline pH solutions.
Advantages:
Unlike conventional pH papers the indicator dyes used in these Camlab test sticks are fixed to the cellulose fibre pads, thus eliminating colour bleeding
Can be left in weakly buffered solutions until the final reaction colour is obtained
High pH readings can be easily read as the test colours are separated far enough apart on the strip
Camlab indicator sticks are made from plastic enabling better handling
Suitable for use in solutions of low ionic strength
