Xylenol orange tetrasodium salt in ACS Reagent grade water, Sigma-Aldrich®

Supplier: SIGMA ALDRICH MICROSCOPY
Description: Xylenol orange tetrasodium salt is a fluorochrome acid dye with complexing and chelating properties that make it useful as an indicator in the spectrophotometric detection and assay of metal ions such as calcium, cadmium, bismuth, zinc, lead, and mercury. Its tetrasodium salt especially is used as an indicator in metal titrations. It changes color from yellow to red between pH 6.4 to 10.4. It has six potentially anionic substituents, one being sulfonate, and is anionic under staining conditions and during most laboratory applications.

Test Kit for free fatty acids

Catalog Number: (1.17046.0001)
Supplier: Merck
Description: Free fatty acids present in an oil or fat sample react with a pH indicator, the colour of which changes depending on the concentration of the free fatty acids. The concentration of the free fatty acids is measured semiquantitatively by visual comparison of the reaction zone of the test strip with the fields of a colour scale. The units of measurement are milligrams of KOH necessary to neutralise the free fatty acids in 1 g of fat sample.
