Description
High-Volume Gravity-Flow Desalting with CentriPure 1500 – Z25M
CentriPure 1500 – Z25M Columns are designed for efficient purification and desalting of proteins and nucleic acids in high-volume applications. These gravity-flow gel filtration columns are ideal for separating large biomolecules (such as antibodies, enzymes, or long nucleic acids) from smaller contaminants like salts, dyes, biotin, and other low molecular weight compounds. Their high recovery rate and >99.99% removal efficiency make them a powerful alternative to time-consuming dialysis or TFF.
The columns are packed with Zetadex-25 Medium, a cross-linked beaded dextran matrix developed by emp BIOTECH, optimized for rapid and reproducible separations. Designed to process up to 150 mL of sample in under 15 minutes, the column ensures minimal dilution and high throughput with consistent results across applications.
