Water

Water (H₂O) is a polar, protic solvent known for its high dielectric constant, hydrogen-bonding ability, and capacity to dissolve a wide range of polar and ionic substances. Often called the "universal solvent," it plays a fundamental role in both natural and laboratory systems.

In the lab, water is essential as a solvent, diluent, and cleaning agent. Deionized and ultrapure water are used in sensitive applications such as HPLC, LC-MS, and biological assays, while purified water supports reagent preparation, rinsing, and sterilization.

Water, sterile, distilled

Supplier: G-Biosciences

Laboratory reagent grade, sterile distilled water for your laboratory needs. This water is purified by steam distillation and sterile filtered for use as a research laboratory reagent. The distilled water is low endotoxin <0.025EU/ml and low conductivity (<10uS). This water is ideal for the preparation of reagents, rinsing of glassware and plasticware, and various other laboratory and research applications. No toxic agents such as DEPC are included in the preparation of distilled water, eliminating interference with enzymatic analysis.

Water for LC-MS

Supplier: Agilent

A portfolio of LC/MS grade solvents that provides best-in-class acetonitrile, methanol and water. With newer LC/MS instruments having lower detection limits and regulations requiring ppb and ppt analysis of compounds, it is important to have LC/MS grade solvents that does not increase baseline noise. These InfinityLab Ultrapure LC/MS solvents have been developed by Agilent R&D and manufactured to have one of the lowest amounts of overall organic and metal contaminants in the industry. Our use of clear borosilicate bottles and smaller volumes (1L bottles) also increases the lot-to-lot quality by reducing the number of contaminants leaching from the bottle.
