pH Indicator Strips
The test strips contain indicator dyes that are covalently bound to the reagent papers and then adhered to plastic strips. Contamination of the solution is therefore prevented even in strong alkaline solutions or from long immersion in weak buffered solutions.
- pH range 1-14, 4 pads
- Non-bleeding – does not contaminate the solution or cross-contaminate neighbouring colour zones
- Length of the plastic strip protects fingers from contact with liquid
- Wide and narrow pH ranges available
