pH-Fix
pH-Fix – Unmatched pH test strips

pH-determination quick, easy, safe

With pH-Fix test strips, you can test the pH value quickly and easily directly at the point of interest. The strips are ready to use at any time and don’t need any calibration, set-up or maintenance. Therefore, pH determination with pH-Fix test strips is very easy, regardless of your experience or chemical background.

Safe analysis by long plastic handle

The long plastic handle safely protects you from coming into contact with the sample. Thus, testing toxic, dangerous or aggressive substances is safely possible.

Several test pads for exact results

pH-Fix indicator test strips feature up to 4 different indicator pads that cover the whole pH range from 0–14. You can chose from a total of 14 different measuring ranges to find the ideal strip for your application. The brilliant color scale is optimally matched and aligned to the test pads on the strips, resulting in quick, easy and safe pH determination.

No bleeding due to color bounded indicator dyes

In contrast to common indicator papers, the indicator dyes in pH-Fix test strips are chemically bound to the test pads. This patented technology safely prevents bleeding of dyes into the sample, even in highly alkaline solutions. Your sample is not contaminated by indicator dyes. Consequently, you can use the solution for further analysis.

The special non-bleeding technology provides additional benefits for you:

• Even in weakly buffered solutions, a safe and reliable pH determination becomes possible,
as the strips can be immersed for a long time until the final reaction color has developed

• The colors of the individual test pads don’t bleed and mix, which assures exact comparison
to the color scale

• Your sample is not contaminated by indicator dyes

Redesigned packages for easy handling

Smart corner

The corner prevents jamming of test strips when closing the cover. The user enjoys a maximum of comfort. By simply skew hold the test strips fall into the smart corner and don´t get jammed. The classic flat box can be concluded easily.

PlopTop tubes - clever packaging for our best seller

The specially engineered PlopTop tubes can be opened and closed with just your thumb. Thus, working with pH-Fix becomes even more comfortable and easier. Design and material guarantee a high degree of stability. The tube is virtually unbreakable and stands firmly on any surface. As the tube is higher than the length of the strips, jamming of test strips when closing the tube are effectively prevented. Thus, you can easily close the tube at any time.

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.
