100 PH indicator test strips 4.5-9paper litmus tester laboratory urine&salivH HF

Description

Features
：
1. Test amniotic fluid, principle (the general human vaginal secretions are acidic, while amniotic fluid is alkaline, pH 7 or higher
Use sterilized cotton to take vaginal secretions, apply to the color block, then compare the color card to find the closest color, and get the pH. If it is not discolored or the color below 6 is not amniotic fluid, the color above 7 is amniotic fluid.
2. Measure the vagina: use a sterile cotton swab to take the vaginal secretions, apply it to the color block, then compare the color card to find the closest color, and get the pH, the general vagina is weakly acidic.
3. Test cosmetics, the principle (because the skin's pH is about 6 is a weak acid, so the pH of the cosmetics is about 6 before it does not harm the skin (the test strip does not change color, the PH value is as shown in Figure 6, no discoloration is good cosmetics) Apply to the color block, then compare the color card to find the closest color, and get the pH
4. Measure the pH of the saliva: the saliva is applied to the color block, then the color card is compared to find the closest color, and the pH is obtained.
5. Measure the pH of the urine: Apply the urine to the color block, then compare the color card to find the closest color, and get the pH.

[Usage]:
The test specimens are prepared separately, and the color blocks are directly immersed in the liquid; 2 seconds to take out, remove excess water, and then compare the value on the color card <7 is acidic, pH = 7 is neutral, pH > 7 is alkali, the greater the alkalinity, the stronger the alkalinity, the stronger the acidity is.
Package included:
100 x PH Test Paper
Precautions for use:
During the test, first tear a small test page, use a glass rod, cotton swab or other sharp object to take a small amount of the object to be tested, drop it on the test page, see the color change, and then sort the color according to the corresponding color on the color palette. You can know the PH value.
