Camlab 1138921 pH-Fix Indicator Paper Test Strips, pH 0.0-14.0 with CE-mark, 6mm x 85mm (Pack of 100)

• 【Sensitive】- These strips can measure pH in unbuffered or very weakly buffered solutions as the sticks can be left in the solution until the final colour change is completed.
• 【CE-marked】- CE-marked for in-vitro-diagnostics 98/79/EG or medical products 93/42/EWG. These are CE-marked for professional use as well as patient self testing.
• 【Colour-fixed】- The indicator dyes for the pH sticks are bound to the cellulose fibres, meaning the possibility of the colour bleeding, even in strongly basic conditions, is avoided.
• 【ISO 13485 certified】- These pH test strips are certified according to the medical device directive ISO 13485.
• 【Body acidity determination】- These strips can be used to test body fluids such as urine, gastric juice, saliva and vaginal pH.

Product Description In contrast to conventional indicator papers the indicator dyes of pH-Fix sticks are substantively bound to the cellulose fibres (DE-PS 24 36 257). As a result the possibility of the colour bleeding, even in strongly basic solutions, is avoided. Directions Immerse the strip in the solution until the final color change is completed. Use to test body fluids such as urine for pH measurement.
