Product Overview
ULTREX® II Ultrapure Water Reagent is engineered to meet the most demanding laboratory requirements, delivering Type I water purity with a resistivity of 18.2 MΩ-cm at 25°C. This reagent-grade water undergoes advanced purification processes, including reverse osmosis, deionization, and ultrafiltration, ensuring ultra-low total organic carbon (TOC) levels (<5 ppb) and endotoxin-free quality (<0.03 EU/mL). Its exceptional purity makes it ideal for applications where even trace contaminants can compromise results, such as high-performance liquid chromatography (HPLC), molecular biology, and cell culture. The water is packaged in high-density polyethylene (HDPE) containers to prevent leaching and maintain integrity during storage. Unlike conventional distilled or deionized water, ULTREX® II undergoes rigorous quality control, including testing for bacteria, nucleases, and particulate matter, guaranteeing consistency across batches. Its neutral pH and absence of interfering ions ensure reliable baseline stability in analytical techniques, while the sealed packaging minimizes exposure to atmospheric CO₂ and particulates. Whether used as a solvent, rinse agent, or blank in spectroscopic analysis, this ultrapure water eliminates variables that could skew experimental outcomes, providing researchers with a dependable foundation for reproducible results.
