LabChem® Eriochrome Black T-Nacl

LabChem® ERIOCHROME BLACK T-NaCl is Eriochrome Black T pre-triturated with sodium chloride, a traditional preparation method that dilutes the concentrated dye into an easily measured, consistently dispensable solid powder. Because Eriochrome Black T is intensely colored and effective in very small quantities, blending it with an inert salt carrier makes it far easier to weigh out a small, precise, reproducible dose. Its pre-mixed formulation improves consistency compared to weighing the pure dye.

It is commonly used as a convenient, pre-diluted solid form of the Eriochrome Black T indicator for EDTA titrations in water hardness determination. Its consistent formulation supports reliable, reproducible indicator dosing across testing sessions. This reagent should be handled, stored, and used according to established laboratory safety procedures and the manufacturer's instructions.
