Product Overview
This Puratronic™-grade anhydrous calcium sulfate delivers exceptional purity (99.993% metals basis), making it indispensable for applications where trace impurities can compromise results. The anhydrous form ensures stability and consistency in moisture-sensitive reactions, while the ultra-low metal content minimizes interference in analytical techniques. Its fine powder form allows for precise weighing and homogeneous mixing in formulations. The material undergoes rigorous quality control to meet the exacting standards of advanced research environments. Unlike technical-grade alternatives, this product eliminates background contamination risks in spectroscopic, chromatographic, or electrochemical analyses. The Puratronic™ designation guarantees lot-to-lot consistency, with comprehensive certificates of analysis provided for each batch. Its inert nature makes it compatible with most organic and inorganic matrices, while the high assay ensures reliable stoichiometric calculations in synthetic protocols.
FAQs
1
What is the difference between Puratronic™ and reagent-grade calcium sulfate?
Puratronic™ grade undergoes additional purification steps to achieve 99.993% metals basis purity, while reagent grade typically contains higher levels of trace metals and other impurities that could interfere with sensitive analyses. 2
Can this product be used in moisture-sensitive applications?
Yes, the anhydrous form is specifically processed to remove all water content, making it suitable for reactions where hydration would be problematic, though proper storage is required to maintain this property. 3
What is the typical particle size distribution for this powder?
The material is milled to a fine powder with most particles falling in the 1-10 micron range, though exact distribution may vary slightly between batches as noted in the certificate of analysis. 4
How should this be stored to maintain its purity?
Store in a tightly sealed container under inert gas if possible, in a cool, dry environment away from direct sunlight and moisture sources to prevent hydration or contamination. 5
Is this product compatible with standard laboratory glassware?
Yes, it can be safely used with borosilicate glass and most common lab plastics, though we recommend verifying compatibility with any specialized equipment or particularly aggressive solvents in your protocol.
