Contains reagents formulated in small, lightweight polyethylene tubing that doubles as a container and test tube.
The simple ratio of the reagent prevents deformation and simplifies operation, allows you to measure the concentration of concentrations of 1 digit lower than the test paper.
By pulling out the line of the tube tip without needing to adjust the pH adjustment, you can simply drill a hole in the tube tip and inhalate the sample into an eyedropper type to see the results.
If used in business activities, please dispose properly in accordance with each relevant law. Otherwise, we recommend that you dispose of the tube as a "burning waste"
