The monohydrate form provides stable handling characteristics while maintaining the compound’s chemical integrity. Its high assay purity makes it particularly suitable for use as an analytical standard or in synthesis protocols where metallic contamination must be minimized. The product’s tightly controlled specifications ensure batch-to-batch consistency, eliminating variability in experimental outcomes. Packaged in sizes optimized for both small-scale research and larger analytical workflows, this calcium oxalate monohydrate represents the gold standard for purity in its class, offering researchers confidence in their results without concerns about metallic interference.
FAQs
1. What is the significance of the “excluding 25ppm max alkali earths” specification?
This specification indicates the product has been specially purified to remove alkali earth metals (like calcium, magnesium, etc.) down to a maximum of 25 parts per million, which is crucial for applications sensitive to these particular contaminants.
2. How does the Puratronic™ grade differ from standard laboratory grades?
The Puratronic™ designation represents an ultra-high purity level (99.9985% metals basis) with significantly lower trace metal impurities compared to standard laboratory grades, making it suitable for the most demanding analytical applications.
3. What is the typical shelf life of this calcium oxalate monohydrate?
When stored in its original, tightly sealed container at room temperature and protected from moisture, the product maintains its specified purity for at least 24 months from the date of manufacture.
4. Are there any special handling precautions for this high-purity material?
While generally stable, this high-purity material should be handled in a clean environment using appropriate labware to prevent contamination, and standard chemical handling precautions should be observed.
5. What documentation is provided with this product?
Each package includes a certificate of analysis detailing the actual purity levels and impurity profile, along with safety data sheets and handling recommendations specific to this high-purity grade.
