Camlab 1138923 pH Fix Indicator Paper Test Strips, 2.0 9.0, 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.
