Eriochrome® Black T, Dry Form in NaCl
Manufacturer: LabChem Inc.
Eriochrome Black T, Dry Form in NaCl from LabChem Inc. is a pre-blended, stable indicator mixture designed for the determination of Total Water Hardness. By dispersing the metallochromic dye in a sodium chloride (salt) carrier, LabChem provides a reagent that avoids the rapid degradation common in liquid EBT solutions. This dry format is the standard for APHA 2340 C and ASTM D1126 methods, ensuring a sharp color transition from wine-red to blue at the titration endpoint.

Lead Times May Vary.
Features:
- Enhanced Shelf Life: Unlike aqueous solutions that expire within weeks, this dry mixture remains stable for 36 months, making it ideal for low-frequency testing.
- Simplified Handling: The NaCl carrier acts as a diluent, allowing for easier measurement of small amounts of indicator without the risk of "over-dyeing" the sample.
- Sharp Endpoint Differentiation: Provides a clear, unmistakable color shift from wine-red (metal-bound) to pure blue (endpoint), critical for accurate Calcium and Magnesium quantification.
- Field & Lab Versatile: Excellent for use in mobile field kits and educational laboratories where liquid reagent stability is difficult to manage.
Safety & Handling:
NOTE! Minimal Hazard: This mixture is generally classified as non-hazardous under GHS standards (Health: 1, Flammability: 0).
