Product Name – Cobalt(II) sulfate heptahydrate, Puratronic™, 99.999% (metals basis) Quantity/Pack Size – 100g, 25g Form – Crystalline powder Grade – Puratronic™ (99.999% metals basis) Application – Trace-metal analysis, high-precision synthesis, electroplating
Product Overview
Cobalt(II) sulfate heptahydrate in Puratronic™ grade delivers unmatched purity (99.999% metals basis), ensuring minimal interference in sensitive analytical procedures. This crystalline powder is meticulously processed to eliminate trace metal contaminants, making it indispensable for applications requiring ultra-low impurity levels, such as atomic absorption spectroscopy (AAS), inductively coupled plasma (ICP), and advanced material synthesis. The heptahydrate form provides consistent solubility in aqueous solutions, while its stable cobalt content guarantees reproducible results across experiments. Unlike standard grades, Puratronic™ cobalt sulfate undergoes rigorous multi-stage purification, including sublimation and zone refining, to meet the exacting demands of research and industrial laboratories. Its hygroscopic nature necessitates storage in airtight containers, but the sealed packaging preserves integrity until use. The product’s uniform particle size distribution further enhances dissolution rates, reducing preparation time for critical protocols. Whether used as a catalyst precursor, electroplating agent, or calibration standard, this high-purity reagent ensures accuracy without compromising performance.
FAQs
1. What is the difference between Puratronic™ and standard cobalt sulfate grades?
Puratronic™ grade undergoes additional purification steps to achieve 99.999% metals basis purity, eliminating trace impurities like iron, nickel, and copper that standard grades (typically 98-99%) may contain. This makes it suitable for applications where even ppb-level contaminants can skew results.
2. Can this product be used directly in electroplating baths?
Yes, but the solution requires pH adjustment and may need buffering agents depending on the target deposit properties. The high purity minimizes defects in the plated layer, but pilot testing is recommended to optimize bath composition for specific substrates.
3. How should I store opened packages to prevent hydration changes?
Transfer the contents to a desiccator with silica gel or store in a vacuum-sealed container. Exposure to ambient humidity can alter the heptahydrate’s water content, affecting molar concentrations in prepared solutions. Reseal the original packaging tightly if unused portions remain.
4. Are there alternatives for applications not requiring 99.999% purity?
For general laboratory use, ACS reagent grade (98-99% purity) cobalt sulfate heptahydrate offers a cost-effective alternative. However, it may introduce detectable metal impurities in trace analysis, making it unsuitable for high-sensitivity techniques like ICP-MS.
5. Does this product contain any additives or anti-caking agents?
No, Puratronic™ cobalt sulfate heptahydrate is free from additives, binders, or anti-caking agents. The crystalline structure is maintained purely through controlled precipitation and drying processes, ensuring no residual contaminants interfere with applications.
