Product Name – Buffer solution, pH 7.413 ± 0.010 (secondary standard) Quantity/Pack Size – 500 ml Form – Liquid Grade – Secondary standard Application – pH meter calibration, lab accuracy
Product Overview
This pH 7.413 ± 0.010 buffer solution is a secondary standard designed for precise pH meter calibration in laboratory settings. Formulated to maintain stability and consistency, it ensures reliable measurements across experiments. The solution adheres to strict quality control, offering a narrow tolerance range (±0.010) for high accuracy. As a secondary standard, it is traceable to NIST (National Institute of Standards and Technology) primary standards, making it suitable for routine lab calibrations where precision is critical. The liquid form allows for easy handling and dispensing, while the 500 ml pack size provides sufficient volume for repeated use without frequent replenishment. The buffer is chemically stable, minimizing degradation over time when stored under recommended conditions. Its neutral pH (7.413) aligns with physiological conditions, making it particularly useful in biochemical and life science applications where maintaining a near-neutral pH is essential. The solution is free from contaminants, ensuring interference-free results in sensitive analytical procedures.
