Description
Non-dyeing pH strips for measuring pH in the range of 4.0-7.0
The package contains one hundred high-quality strips with paper tips coated with a special mixture of chemical compounds—indicators and dyes—that are covalently bonded to the cellulose of the indicator paper. This feature gives these strips a significant advantage over indicator papers because they are free from the problem of colored indicator leakage. The strips can be left in the measured solution for extended periods without contaminating the measured medium.
Special indicator: pH 4.0 - 4.4 - 4.7- 5.0 - 5.3 - 5.5 - 5.8 - 6.1 - 6.5 - 7.0
Package: 100 pieces
