Product Description
Di-Potassium Hydrogen Phosphate Trihydrate, also known as potassium phosphate dibasic trihydrate, is a high-purity chemical compound widely used in laboratories for its buffering capabilities. This analytical-grade reagent is essential for maintaining stable pH levels in biological and chemical experiments. Whether you’re a student setting up a basic buffer solution or a researcher conducting advanced biochemical assays, this product ensures reliable results.
The P.A. (Pro Analysis) grade designation means it meets strict purity standards, making it suitable for sensitive applications where impurities could interfere with outcomes. The trihydrate form provides excellent solubility in water, allowing for easy preparation of solutions at various concentrations. Many researchers prefer this compound for its stability and consistency in performance.
In educational settings, this chemical serves as a fundamental component in teaching buffer systems and pH regulation. Its versatility extends to molecular biology, where it’s used in DNA extraction protocols and protein purification processes. The 250g pack size offers an ideal balance between quantity and shelf life, making it perfect for both small-scale experiments and regular laboratory use.

Key Applications in Laboratories
This versatile chemical finds applications across various scientific disciplines. In biochemistry labs, it’s commonly used to prepare phosphate-buffered saline (PBS) solutions, which are fundamental in cell culture and immunological studies. The compound’s ability to maintain physiological pH makes it indispensable in these applications.
Analytical chemists appreciate its role in spectrophotometric analysis and chromatographic techniques. The consistent quality of this P.A. grade product ensures reproducible results in quantitative analyses. For environmental testing laboratories, it serves as a component in water analysis protocols, particularly in determining phosphate levels.
In academic institutions, students working on practical experiments benefit from its predictable behavior in titration exercises and pH adjustment demonstrations. The compound’s stability at room temperature makes it safe for educational use while still providing professional-grade performance.
Safety and Handling Considerations
While di-potassium hydrogen phosphate trihydrate is generally considered safe for laboratory use, proper handling procedures should always be followed. Always wear appropriate personal protective equipment, including gloves and safety goggles, when working with chemical reagents. Store the product in a cool, dry place away from incompatible substances.
The compound is non-flammable and non-toxic at standard concentrations, but as with any laboratory chemical, avoid ingestion and direct contact with skin or eyes. In case of accidental exposure, rinse thoroughly with water and seek medical attention if irritation persists. Proper disposal methods should be followed according to local regulations for chemical waste.
Why This Product Stands Out
What sets this particular di-potassium hydrogen phosphate trihydrate apart is its combination of Merck’s rigorous quality control and eqipped’s customer-focused approach. The P.A. grade certification guarantees minimal impurities, which is crucial when working with sensitive analytical techniques or biological samples.
The trihydrate form offers practical advantages in solution preparation, as it dissolves readily without requiring excessive heating. This makes it particularly suitable for educational settings where students are learning proper laboratory techniques. The 250g packaging provides enough material for multiple experiments while maintaining freshness throughout its shelf life.
For researchers working on long-term projects, the consistency between batches ensures that experimental conditions remain uniform over time. This reliability is especially important in fields like molecular biology where even slight variations in buffer composition can affect results.
FAQs
Frequently Asked Questions
What is the difference between di-potassium hydrogen phosphate and mono-potassium phosphate?
Di-potassium hydrogen phosphate (K2HPO4) has two potassium ions and one hydrogen phosphate ion, making it more basic than mono-potassium phosphate (KH2PO4), which has one potassium ion and two hydrogen phosphate ions. This difference affects their buffering capacity at different pH ranges.
Can I use this product for food applications?
While di-potassium hydrogen phosphate is sometimes used in food processing, this P.A. grade product is specifically formulated for laboratory use and is not certified for food applications. For food-grade requirements, specialized products would be necessary.
How should I store this chemical to maintain its quality?
Store the product in its original, tightly sealed container at room temperature (15-25°C). Keep it away from moisture and direct sunlight. Proper storage ensures the chemical remains stable and effective throughout its shelf life.
What is the typical shelf life of this product?
When stored correctly, di-potassium hydrogen phosphate trihydrate typically has a shelf life of 2-3 years. Always check the expiration date on the packaging and inspect the product for any signs of degradation before use.
Can this product be used in DNA extraction protocols?
Yes, this high-purity di-potassium hydrogen phosphate is suitable for molecular biology applications including DNA extraction. Its analytical grade purity helps prevent contamination that could interfere with sensitive biological assays.
