Product Overview
This Puratronic™ grade barium nitrate delivers exceptional 99.999% purity on a metals basis, ensuring negligible trace metal contamination for critical laboratory applications. The crystalline powder form provides consistent solubility and reactivity, making it suitable for demanding chemical processes where impurity levels must be strictly controlled. Its high assay specification guarantees reliable performance in analytical procedures, while the Puratronic™ certification confirms adherence to rigorous quality standards for research-grade chemicals. The product maintains stability under standard laboratory conditions when stored properly, with minimal hygroscopicity compared to lower-grade alternatives. Its uniform particle size distribution enhances handling precision during weighing and dispensing operations. The absence of detectable metallic impurities (below 10 ppm for most elements) makes this grade particularly valuable for applications requiring ultra-low background interference. Compatible with most common laboratory solvents, this barium nitrate variant offers versatility across different synthesis protocols while maintaining its high purity profile throughout typical reaction conditions.
FAQs
1. What distinguishes Puratronic™ grade from standard barium nitrate?
The Puratronic™ designation indicates a metals purity of 99.999%, with individual metallic impurities typically below 10 ppm, compared to standard grades that may contain 100-1000 ppm of metal contaminants. This makes it suitable for applications where trace metal interference must be minimized.
2. Can this product be used for preparing optical glass formulations?
Yes, the ultra-low metallic impurity profile of this Puratronic™ grade makes it particularly suitable for optical glass manufacturing where even trace amounts of certain metals can affect the refractive index and transparency of the final product.
3. What is the typical moisture content of this crystalline powder?
When properly stored in sealed containers, this barium nitrate maintains moisture content below 0.1% by weight, though it may gradually absorb moisture if exposed to humid environments for extended periods.
4. Are there any special handling precautions beyond standard chemical safety?
While standard barium compound precautions apply, the ultra-high purity means there’s reduced risk of unexpected reactions from metallic impurities. However, the same toxicity considerations for barium compounds remain applicable.
5. How does the particle size distribution compare to reagent-grade alternatives?
This Puratronic™ grade features a more uniform particle size distribution (typically 90% between 50-200 microns) compared to reagent grades, which helps ensure consistent reaction kinetics and more precise weighing during laboratory procedures.
