Ultrapure Sodium Phosphate Dibasic Anhydrous for Laboratory Research – Sodium phosphate dibasic anhydrous is widely used in laboratory settings for buffer preparation, pH regulation, and biochemical reactions. This high-purity reagent ensures consistency in research applications where phosphate buffering is required.
Ideal for Buffer Preparation & pH Control – With a controlled pH range of 8.4 - 9.6 in a 1% aqueous solution, this reagent is essential for biochemical research, molecular biology, and analytical chemistry.
Low Heavy Metal & Impurity Levels – Contains ≤ 1 ppm lead, ≤ 1 ppm arsenic, and ≤ 10 ppm fluoride, minimizing contamination risk in sensitive experimental conditions.
RNase- & DNase-Free for Molecular Biology Applications – Each batch is rigorously tested to confirm the absence of RNase and DNase, ensuring suitability for DNA, RNA, and protein studies.
Used in Analytical & Biochemical Research – Sodium phosphate dibasic anhydrous is frequently used in buffer systems, protein crystallization, and pH stabilization processes.
