Bullet Points:
1、0 – 14 PH Test Paper: Each pH strip is made of good quality litmus paper, won＇t bleed like normal litmus paper, can get fast, accurate and reliable results in just seconds.
2、Full PH Range: it can test from 0 to 14, pH 0-14 color chart for you quickly compare the test results with the 4 colors pH panels on the card board, to obtain your solutions＇ pH.
3、Easy to Apply: Test pH of a solution, you simply dip the pH strip into your solution, and the strip will change color immediately.
4、Wide Application: The PH paper test strips are good for detecting body acid alkaline pH level by testing urine, saliva; Also can be applied for schools, lab, drinking water, swimming pools, fish tank, hydroponics, aquariums, food, etc.
5、Lightweight Design: Each test paper strip size is 3.15 x 0.24 inch/ 8 x 0.6 cm, they are packed in a portable box, convenient for use and carry; Package includes 2 boxes, 100 pieces for each box.
Sample requirements:
1. Take 5-10ml of sample and take the supernatant to test after standing.
2. The test is carried out at room temperature around 25°C.
Testing method:
1. Immerse the reaction area of the test strip in the solution to be tested for 1-2 seconds, take out the test strip, and shake off the excess water on it.
2. After 1 minute, compare the color of the reaction zone of the test strip with the color of the color chart to determine the test value of solution to be tested.
3. The color comparison time should be controlled at about 30s, too long or too short will affect the reading.
Precautions:
1. When removing the test paper, do not touch reaction end of test paper, so as not to contaminate the test paper and affect test results.
2. After taking out the required number of test papers, keep the remaining test papers sealed and protected from light.
3. Try to keep the liquid to be tested as colorless or light-colored. Before testing the liquid with too dark color, it can be dehydrated with activated carbon adsorption. If the liquid to be tested is relatively turbid, let it stand for a period of time, and take the clear part for testing after it settles.
