Diphenylcarbazide Indicator Solution, 1% Alcoholic
Manufacturer: LabChem Inc.
Diphenylcarbazide, 1% Alcoholic from LabChem Inc. is a high-precision indicator solution formulated for the colorimetric determination of hexavalent chromium (Cr6+). By pre-dissolving the indicator in an ethanol matrix, this reagent provides immediate reactivity and stable performance, eliminating the labor and safety risks of manually dissolving powdered diphenylcarbazide.
Description
Features:
- Exceptional Sensitivity: Reacts specifically with hexavalent chromium in acidic solutions to produce a vivid red-violet color complex (detectable at 540 nm).
- Standardized Protocol Support: Optimized for use in wastewater monitoring, soil analysis, and industrial hygiene protocols following EPA and OSHA guidelines.
- Time-Efficient: Pre-mixed solution reaches maximum color development in approximately 5 to 10 minutes, facilitating rapid throughput for batch analysis.
- Solubility & Stability: Formulated in alcohol to prevent the indicator from precipitating out of solution, a common issue with aqueous-only preparations.
Safety & Regulatory Information:
DANGER! Highly Flammable & Reproductive Hazard: This product contains ethanol and is a flammable liquid. It also contains chemicals known to the State of California to cause birth defects or other reproductive harm.
- Personal Protection: Wear acid/solvent-resistant gloves, safety goggles, and a lab coat. Handle only in a well-ventilated area away from heat, sparks, or open flames.
- Storage: Store in a cool, "flammables" safety cabinet. Amber glass packaging is used to protect this light-sensitive reagent from oxidation; it should be discarded if the solution turns brown.
- Handling: Avoid inhalation of vapors. Ensure an emergency eyewash station and safety shower are in the immediate vicinity.
