Potassium phosphate Dibasic (Powder)

Description

Potassium Phosphate Dibasic (Powder) Catalog B2010694 (100 g)

Potassium Phosphate Dibasic (KHPO) is a versatile, high-purity inorganic salt extensively used as a buffer component, pH stabilizer, and reagent in molecular biology and chemical workflows. Supplied as a 100 g powder (Catalog B2010694), this biotechnology-grade reagent offers exceptional consistency and solubilitymaking it ideal for preparing phosphate buffers, culture media, enzyme assays, and chemical reaction systems.

Characterized by its buffering capacity in the physiological pH range (~7.28.2), this salt supports a stable environment while minimizing ionic variation. It is routinely employed in lactic dehydrogenase assays, propagation of bacterial cultures, and creating phosphate-buffered solutions for analytical and preparative applications. Manufactured under strict purity control and processed with ultrapure water and sterile filtration, it facilitates reproducible results and minimizes interference in sensitive assays. The powder format allows precise weighing and solution preparation, while room-temperature stability adds convenience to everyday lab use. Custom bulk packaging is also available to support long-term or high-throughput processes.

Why researchers choose this product:

• High-purity, biotech-grade potassium phosphate dibasic ensures reliable buffering and assay performance
• Ideal for pH stabilization, buffer formulation, and enzyme reaction workflows
• Room-temp stable powder format allows accurate weighing and solution reproducibility
• Prepared under ultrapure conditions with filtration for minimized contamination
• Available in bulk for extensive research and production needs

Indication for Use:
This product is intended for Research Use Only (RUO). It is not for diagnostic or therapeutic applications.
