Bromocresol green sodium salt 0,04% in aqueous solution, Sigma-Aldrich®

Catalogus nummer: (318701-500ML)
Leverancier: SIGMA ALDRICH MICROSCOPY
Omschrijving: Bromocresol green is a sulfonephthalein dye. It is mainly used for measuring serum albumin. In acidic conditions, bromocresol green interacts with albumin, thereby resulting in an increase in absorbance at 630 nm. The change in absorbance is linked with the concentration of albumin. Bromocresol Green is also a pH indicator, changing from yellow (pH 3.8) to blue color (5.4). It is widely used as a colloidal pigment.

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

Leverancier: SIGMA ALDRICH MICROSCOPY
Omschrijving: 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.
