Easy and reliable 4.5-9 pH 100 Test Strips.

Non-bleeding indicator sticks for rapid reading of weakly buffered or strongly alkaline pH solutions.


  • Unlike conventional pH papers the indicator dyes used in these Hawksley 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
  • Hawksley indicator sticks are made from plastic enabling better handling
  • Suitable for use in solutions of low ionic strength
