MColorpHast PH Indicator 4.0 7.0 Universal Mcolorphasttm 100 test strips
The pH value is a measure of the acidic or basic character of different substances in aqueous solutions. The pH value of a sample can be determined on site using pH indicator strips. They can be used immediately. pH test sticks are suitable for one-time use. They are therefore easy to use and can be carried out safely by chemical laypeople. The long plastic handle protects the user from contact with the sample. This enables a safe examination without contamination. pH indicator strips from Merck have up to 4 different indicator fields that cover the entire specified pH range. The brilliant color scale is optimally coordinated in position and color with the test fields on the strip. The result: a quick, easy and reliable determination of the pH value. The colors of the individual color fields do not run into each other. This ensures an exact comparison with the color scale. Application: Hold the test strip in the medium to be measured for a few seconds. Examples of pH values: pH=0 Battery acid pH=1 Stomach acid pH=2 Citric acid pH=3 Cola pH=4 Tomatoes pH=5 Coffee, black pH=6 Milk pH=7 Water CO2-free pH=8 Sea water pH=9 Dissolved baking soda pH=10 Dissolved digestive tablets pH=11 Ammonium salt solution pH=12 Soapy water pH=13 Bleach pH=14 Pipe cleaner Illustration may differ from the original Test strips - Test - Strips - Roll - Paper - Indicator - pH
