The Agilent ZORBAX StableBond 300 C18 column, featuring a 2.1 x 50 mm dimension and a 3.5 µm particle size, is engineered for robust and efficient reversed-phase liquid chromatography. Its specially bonded C18 phase and 300 Å pore size make it highly suitable for the analysis of large biomolecules such as peptides, polypeptides, protein digests, and synthetic oligonucleotides. The StableBond silica offers exceptional stability under low pH conditions, delivering reliable performance and reproducible separations for acidic mobile phase environments.

This column is ideal for workflows in proteomics, pharmaceutical analysis, complex mixture characterization, and biomarker discovery. Researchers benefit from its consistent peak shapes and high resolution, which are essential for qualitative and quantitative applications. The design ensures minimal protein adsorption and excellent column life, making it suitable for method development and high-throughput analyses.

It is compatible with major HPLC and UHPLC systems, including Agilent 1100, 1200, and Infinity Series, as well as comparable chromatographic instruments. The column integrates seamlessly with other ZORBAX columns and Agilent sample preparation products to support comprehensive analytical strategies across research, QC, and regulated laboratory environments.
