Pehanon pH 1,8 - 3,8 test strips unify pH indicator and reference color chart on one strip. Any sample color has the same effect on both, the reference colors and the reactive pad, allowing unadulterated pH reading even in colored solutions. measuring range: 1.8-2.1-2.4-2.7-3.0-3.2-3.5-3.8

pH-Fix 7.5-9.5 indicator strips with chemically bound indicators are the bench mark for pH testing with test strips. The fixation prevents bleeding and therefore contamination of the sample. measuring range: pH 7.5-7.9-8.2-8.4-8.6- 8.8-9.1-9.5

Potassium iodate starch paper test paper allows the rapid detection of sulfite and sulfur dioxide. The paper is used in food analyzing laboratories.

pH-Fix 4.0-7.0 indicator strips with chemically bound indicators are the bench mark for pH testing with test strips. The fixation prevents bleeding and therefore contamination of the sample. measuring range: pH 4.0-4.4-4.7-5.0-5.3-5.5- 5.8-6.1-6.5-7.0

Large indicator pad for easy matching to the color chart and precise pH determination Indicator dye is fixed to the test strip to reduce the risk of dye bleed into the sample Long sturdy handle protects the user from contact with the sample Easy-to-read color chart exactly matches both color and...

pH-Fix 5.1-7.2 indicator strips with chemically bound indicators are the bench mark for pH testing with test strips. The fixation prevents bleeding and therefore contamination of the sample. measuring range: pH 5.1-5.4-5.7-6.0- 6.3-6.6-6.9-7.2

CO2 Indicators are intended to be used in conjunction with carbon dioxide generating systems used for the growth of bacterial cultures. The CO2 Indicator signify that the carbon dioxide concentration in the atmosphere is 3% or greater in jar or pouch incubation systems. BD products are intended for...

Individual pads on a polystyrene strip. These are packaged in the PopTop vial which is molded with a desiccant liner for protection from moisture.

The Reflectoquant® Ammonium test includes test strips and all necessary additional reagents and is suitable for determination potentially harmful pollution in surface and ground water, which are caused by ammonium compounds. Depending on the pH level ammonia is formed, which is a potent toxin...

Pehanon pH 1,0 - 12,0 test strips unify pH indicator and reference color chart on one strip. Any sample color has the same effect on both, the reference colors and the reactive pad, allowing unadulterated pH reading even in colored solutions. measuring range: 1-2-3-4-5-6-7-8-9-10-11-12
