The patented pH-Fix technology stands for a high quality, color-fixed pH test strip system. For many years chemists as well as inexperienced users have appreciated pH-Fix's optimal usability, reliability, and precision. The long handle prevents fingers from coming into contact with the sample. It adds handling convenience and increases safety of operation. This allows a high standard of "workplace safety" when testing aggressive solutions. To prevent bleeding, the pH-indicator is chemically bound to the cellulose fiber. Unlike classic pH papers, pH-Fix effectively protects the sample against contamination and enables measurements even in weakly buffered or strongly alkaline solutions. Four different color blocks for each pH-value (pH-Fix 0-14) ensure highly precise pH-determination and make the application rapid and reliable.

Manufacturer: HACH Brand: Hach Company

The most widely used disinfectant for drinking water, chlorine is also important for sanitizing swimming pools, cooling towers, other industrial equipment, and in the treatment of municipal wastewater. Its measurement and control are vital for both safety and economic reasons. Chlorine exists in water as "free" chlorine (hypochlorite) or "combined" chlorine (chloramines). With Hach Water Quality Test Strips, technicians in the field can test many samples in only a few minutes and make immediate evaluations on-site. No measuring, set-up, clean-up, or chemical handling are necessary. Hach test strips are also used in laboratories all over the world for pre-test screening-to detect the presence of materials that might interfere with lab testing. Contains 50 tests. *This product has not been evaluated to test for chlorine and chloramines in medical applications in the United States.
