ASTM Reagent Water is a highly purified water meeting ASTM standards, used in pharmaceutical and analytical laboratories for preparation of reagents, standard solutions, and high-precision analytical experiments requiring minimal ionic or organic contamination.
🏭⚗️ Production
Produced by multi-stage purification processes including distillation, deionization, and/or reverse osmosis under strictly controlled conditions to achieve ASTM-grade water purity. Supplied in chemically resistant, tightly sealed containers to prevent contamination and maintain quality. Quality is verified according to ASTM specifications for conductivity, resistivity, total organic carbon (TOC), and microbial limits.
🔬 Properties
A clear, colorless, odorless liquid with extremely low ionic content, minimal dissolved gases, and negligible organic impurities. Chemically stable under proper storage conditions. Exhibits excellent solvent properties for analytical and pharmaceutical use.
🧪 Applications
Used in pharmaceutical and analytical laboratories for preparation of reagents, buffers, and standard solutions. Ideal for high-precision titrations, spectroscopy, chromatography, and any procedure requiring contamination-free water. Ensures reproducibility and accuracy in sensitive laboratory experiments.
⚠️ Safety
Non-toxic and non-hazardous; standard laboratory precautions should be observed to prevent contamination. Store in a cool, dry, tightly sealed container. Dispose of according to laboratory protocols if contamination occurs.
