100 PH indicator test strips 4.5-9 paper litmus tester laboratory urine saliva U

ITEM NAME:100 PH indicator test strips 4.5-9 paper litmus tester laboratory urine saliva U Features ï ¼Å¡ 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. There are many, as long as the aqueous solution can be measured, not enumerated Specification: Brand new Box Size: approx. 87*67*11mm Conversion: 1cm=0.39inch/1 inch=2.54cm PH range: 4.5-9.0 Quick and easy to use. Easy to carry. Great product to measure and inspect Saliva and Urine. [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 includ.You can know the PH value. Test amniotic fluid, principle (the general human vaginal secretions are acidic, while amniotic fluid is alkaline, pH 7 or higher. PH range: 4.5-9.0. 100 x PH Test Paper. 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. ).
