Why Use a Non-Bleeding pH Test Strip?

What exactly does it mean when we see non-bleeding test strips? Unlike common indicator papers, non-bleed is a patented technology whereby the test strips are chemically bound to the test pads. This safely prevents the dyes from bleeding into the sample which prevents contamination and allows you to continue with further analysis of the solution. You will notice that the non-bleed technology continues to work effectively even in highly alkaline solutions.

What benefits can you expect to see by using this technology?

• A safe and reliable pH determination becomes possible even in weakly buffered solutions as the strips can be immersed until the final reaction colour has developed
• As the test pads don’t bleed and mix, you can ensure an exact comparison to the colour scale
• Lastly, your sample is not contaminated by indicator dyes

With Westlab’s 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 the Westlab pH-Fix test strips is very easy, regardless of your experience or chemical background.
