Product Overview

Ammonium hydroxide, 20% ULTREX® II Ultrapure reagent is a high-purity solution designed for demanding laboratory applications where trace metal contamination must be minimized. This reagent-grade ammonium hydroxide is manufactured under stringent quality controls to ensure consistency and reliability in critical procedures. The ULTREX® II designation guarantees ultra-low levels of impurities, making it suitable for sensitive analytical techniques, including atomic absorption spectroscopy (AAS), inductively coupled plasma (ICP), and other trace analysis methods. The 20% concentration provides an optimal balance between reactivity and handling safety, while the ultrapure grade ensures minimal interference in experimental results. Packaged in a high-density polyethylene (HDPE) bottle, this solution maintains its integrity during storage and transport. Whether used for sample preparation, pH adjustment, or as a solvent, this ammonium hydroxide solution delivers the precision required for advanced research and quality control applications.

FAQs

1. What is the shelf life of this ammonium hydroxide solution?

When stored in its original, tightly sealed container at room temperature, this solution remains stable for up to 24 months from the date of manufacture.

2. Is this solution compatible with glassware?

While it can be used with glassware, prolonged exposure may cause etching. For long-term storage, HDPE or PP containers are recommended.

3. Can this be used as a substitute for standard reagent-grade ammonium hydroxide?

Yes, but its ultrapure grade makes it more suitable for applications requiring minimal trace metal contamination, which may not be necessary for general use.
