Product Overview
Ammonium hydroxide (29% CMOS grade) is a high-purity, aqueous ammonia solution specifically formulated for critical laboratory and industrial applications. This reagent-grade solution ensures minimal metallic impurities, making it suitable for semiconductor manufacturing, photolithography, and other precision processes where trace contamination could compromise results. The 29% concentration provides an optimal balance between reactivity and handling safety, reducing the need for dilution in most applications. Its CMOS-grade certification guarantees compliance with stringent electronic-grade standards, ensuring reliability in microfabrication and advanced material synthesis. The solution is stabilized to prevent degradation during storage and transportation, maintaining consistent performance over time. Packaged in chemically resistant containers, this ammonium hydroxide solution meets the exacting requirements of research laboratories, quality control departments, and high-tech manufacturing facilities. Its versatility extends to general analytical chemistry where high-purity ammonia solutions are required for accurate titrations and pH adjustments.
FAQs
1. What is the shelf life of this CMOS-grade ammonium hydroxide solution?
When stored unopened in its original container at room temperature, this solution maintains its specified purity for 12 months from the date of manufacture.
2. Is this solution compatible with standard laboratory glassware?
The 29% concentration can be safely used with borosilicate glass, though prolonged exposure may require PTFE-lined containers for optimal storage.
3. What alternatives exist for applications requiring lower ammonia concentrations?
Diluted solutions can be prepared from this concentrate, or pre-diluted 10% and 5% ammonium hydroxide solutions are available for less demanding applications.
4. How should this solution be stored to maintain its CMOS-grade purity?
Store in a cool, well-ventilated area away from acids and oxidizing agents, with the container tightly sealed to prevent ammonia loss and contamination.
5. What documentation is provided with this product for quality verification?
Each batch includes a Certificate of Analysis detailing the impurity profile, concentration verification, and compliance with CMOS-grade specifications.
