FAQs
1. What is the solubility of sodium phosphate dibasic 7-hydrate in water?
Sodium phosphate dibasic 7-hydrate is highly soluble in water, typically dissolving at a rate of approximately 85 g/L at 20°C, forming clear, colorless solutions suitable for buffer preparation.
2. Can this reagent be used for preparing phosphate-buffered saline (PBS)?
Yes, this ACS-grade sodium phosphate dibasic 7-hydrate is commonly used as a key component in PBS formulations due to its purity and consistent pH buffering capacity.
3. What is the typical shelf life of this product when stored properly?
When stored in a cool, dry place with the container tightly sealed, this reagent maintains its stability and specified purity for at least 3 years from the date of manufacture.
4. Is this product compatible with common laboratory glassware?
The crystalline form is non-corrosive to standard borosilicate glassware, though prolonged exposure to highly concentrated solutions may require inert containers for long-term storage.
5. How does the ACS grade differ from technical or food grades?
ACS grade meets stringent purity requirements established by the American Chemical Society, with maximum allowable impurities typically below 0.01%, unlike technical or food grades which have higher impurity tolerances.
