Agilent’s DXT, nominal Mw 20,000 Da, is a high-purity dextran polymer designed for use in advanced life science research applications. With a defined average molecular weight of 20,000 Daltons, this polysaccharide serves as an essential standard or matrix in various analytical and preparative workflows, including size exclusion chromatography SEC, gel filtration, and osmometry. Its consistent molecular profile enables accurate calibration of chromatographic columns and precise assessment of molecular size distributions in proteins, peptides, and other biopolymers. This dextran is ideal for laboratories working on biomolecule characterization, bioprocess development, and quality control.

Optimized for solubility and stability in aqueous solutions, it can be readily integrated into protocols requiring inert matrix materials or viscosity modulation. It is fully compatible with Agilent’s suite of chromatography systems such as the 1260 Infinity II and 1290 Infinity II, as well as with major third-party liquid chromatography platforms. In addition, it complements other molecular weight standards and can be combined with Agilent consumables and reagents to support comprehensive workflow integration. The product undergoes rigorous quality testing to ensure batch-to-batch consistency and reliability, making it an indispensable component for accurate molecular weight determination and reproducible analytical results.
