Product Overview
Potassium phosphate, dibasic (K₂HPO₄) in ultrapure powder form is a high-grade biochemical reagent designed for precision in laboratory applications. This bioreagent-grade compound offers exceptional purity, minimizing contaminants that could interfere with sensitive experiments. Its fine, free-flowing powder form ensures easy dissolution and accurate dosing, making it ideal for preparing buffers, culture media, and analytical solutions. The dibasic nature of this phosphate salt provides excellent buffering capacity in the physiological pH range (6.0–8.0), which is critical for maintaining stable conditions in enzymatic reactions and cell culture systems. The ultrapure grade undergoes rigorous quality control to meet stringent laboratory standards, ensuring consistency across batches. Its low heavy metal content and minimal endotoxin levels make it suitable for demanding applications where trace impurities can compromise results. This product is packaged in a 500 g pack, offering an optimal balance between bulk savings and freshness for frequent lab use. The airtight, moisture-resistant packaging preserves the powder’s integrity, preventing clumping or degradation over time. Whether used in molecular biology, protein chemistry, or analytical testing, this dibasic potassium phosphate delivers reliable performance for researchers and technicians.
FAQs
1. What is the solubility of this dibasic potassium phosphate powder?
This ultrapure dibasic potassium phosphate powder is highly soluble in water, typically dissolving at a rate of 167 g/L at 20°C, forming a clear, colorless solution.
2. Can this product be used for cell culture applications?
Yes, the bioreagent grade and ultrapure quality make it suitable for cell culture media preparation, as it minimizes cytotoxic contaminants that could affect cell viability.
3. How should this powder be stored to maintain its purity?
Store the powder in a cool, dry place in its original airtight container, away from direct sunlight and moisture to prevent hydration or contamination.
4. Is this dibasic potassium phosphate compatible with other phosphate buffers?
Yes, it can be combined with monobasic potassium phosphate to create phosphate-buffered saline (PBS) or other custom buffer systems for specific pH requirements.
5. What alternatives exist if this grade is unavailable?
For less critical applications, reagent-grade or ACS-grade dibasic potassium phosphate can be used, though they may contain higher impurity levels affecting sensitive assays.
