Description of Macherey Nagel 92115 PH Fix Unmatched Strips

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. item package weight: 3.0 pounds.

Inaccurate PH Testing Strips: Don't Waste Your Money

Based on our own experience these industrial and scientific PH testing strips were ineffective and produced inconsistent results. The only pro is that they are easy to use. However, the cons outweigh any benefits - the strips did not match our expectations for accuracy and proved to be a waste of money .We do not recommend this product for anyone seeking reliable PH testing in their substance analysis instrumentation..

Pros
  • Easy to use and read pH results
Cons
  • Not very versatile, can only be used for pH testing and nothing else

Good for color blind chemists!

I haven't tested with standard buffers, but the readings seem accurate. Having three colorimetric strips is important for those who are color blind and have difficulty with other wide pH indicator strips (these strips are attached to a plastic strip, making dipping a bit easier than thin strips).

Pros
  • Lots of positive vibes
Cons
  • Fading
