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 of the possibility of the colour bleeding, even in strongly basic solutions, is avoided.
Measurement of pH value is possible even in unbuffered or very weakly buffered solutions since the sticks can be left in the solution until the final colour change is completed. CE marked versions available.
CE-mark for medical applications
Some pH-Fix test strips are tested and approved for medical applications and carry a CE-mark for in-vitro-diagnostics 98/79/EG or medical products 93/42/EWG. They meet the special demands of health care professionals and ensure safe results for medical pH-testing.
ISO 13485 certified
As a medical device manufacturer, MACHEREY-NAGEL is certified according to the medical device directive ISO 13485. We are among the few manufacturers that can offer pH-tests with CE-mark for professional use as well as for patient self testing.
Easy determination of body acidity
The urine pH-value generally reflects the personal diet but can also be influenced by a large variety of medications available from different manufacturers.
Checking pH of gastric juice
Aspirate obtained after placing a nasogastric tube must be acidic. The pH is checked to ensure the correct placement of the nasogastric tube prior to the administration of feed or medication.
pH-control during pregnancy
A change in vaginal pH-value is an indicator for bacterial infection. During pregnancy, such infection may untreated lead to premature birth.
Quick-check of dialyzer reuse
Acid containing reagents are used for the disinfection of dialyzers. pH-Fix 3.6€“6.1 is an easy and reliable tool to ensure, that the cleaning agent is completely rinsed out prior to the next use.
