Universal indicator paper is designed to determine the level of acidity of liquid media. It is thin paper strips with special impregnation. Upon contact with an acidic liquid medium, the indicator zone changes its color depending on the level of its acidity. Color is an indicator that helps determine the pH level on a scale of 0 to 12 units. The packaging has a color reference scale with which to compare the strip that has changed color under the action of the medium.
The use of pH test strips includes the following steps. The strip is moistened in the test solution for 1 second so that the indicator zone is completely immersed in the solution. Then the strip is removed, and the color of the indicator zone of the strip is immediately compared with the colored squares of the comparison scale on the side surface of the plastic tube. Assess the similarity of staining and determine the pH value.
In the cosmetics industry
With the help of litmus indicator paper, the correct combination of emulsifiers, stabilizers is determined in the production of creams, lotions, masks and other cosmetics.
Indicator paper for chemical production
Universal indicator paper for determining the pH level of process media and all other liquids and media.
Medicine and laboratory research
Litmus indicator paper is applicable in laboratory studies of urine, saliva and other medical tests.
Indicator paper in research activities
It is difficult to overestimate the role of litmus paper in scientific developments. Determining the pH of a solution, its acidity or alkalinity is necessary for any study.
In addition, you can buy indicator paper for microbiology and analytical chemistry.
Litmus indicator paper for determining the pH of pool water
Full preparation of water for the pool is possible only after determining the pH of the water. It is after determining acidic or alkaline water that further actions can be carried out: pH regulation, addition of disinfectants, algicides, flocculants, etc.
pH measuring range:0-12.
Number of strips in a tube:100 pieces.
Production:Czech Republic, Brno.
Designed to determine the pH in the range of 0-12 in increments of 1 pH unit. In this case, the error can fluctuate around "1" (units) for concentrated solutions and reach 3 in the case of determining the pH of weakly concentrated solutions (water, soil extracts, etc.).
