محلول بافر آمونیوم برای pH 11-10

Ammonium Buffer Solution for Complementary pH 10–11 is a high-purity, pharmacopeial-grade solution used in pharmaceutical and analytical laboratories for pH adjustment, method complementing, and calibration procedures in alkaline conditions, particularly in analyses involving ammonia and metal–complex formation.

🏭⚗️ Production
Produced under strictly controlled conditions to ensure high purity, accurate pH range, and minimal contamination. The solution is formulated using precise concentrations of ammonium salts and ammonia to achieve a stable complementary pH range of 10–11 and is supplied in sealed, chemically resistant containers to prevent contamination, evaporation, and CO₂ absorption. Quality is verified according to pharmacopeial and analytical standards for pH accuracy and stability.

🔬 Properties
A clear, colorless aqueous solution with a defined alkaline pH range of 10–11. Stable under proper storage conditions but may exhibit pH changes upon exposure to air, CO₂ absorption, contamination, or extreme temperatures. Exhibits a characteristic mild ammoniacal odor.

🧪 Applications
Used in pharmaceutical, environmental, and analytical laboratories as a complementary buffer for pH adjustment and calibration in alkaline ranges. Ideal for complexometric titrations (such as EDTA titration of metal ions), spectrophotometric analyses, and methods requiring controlled ammoniacal pH environments. Suitable for applications where stable high-pH buffering is essential for accurate and reproducible measurements.

⚠️ Safety
Alkaline and may cause irritation to skin, eyes, and respiratory system. Avoid ingestion and inhalation of vapors. Wear appropriate protective gloves, goggles, and lab coat when handling. Store in a cool, dry place in tightly sealed containers, away from acids and incompatible materials. Dispose of according to laboratory and environmental safety regulations.
