Fast Centrifugation Desalting for Longer Oligonucleotides and Proteins
Desalting Centrifugation Column: MINI Formats (MWCO 20 nt/bp)
CentriPure MINI Desalting Columns with a 20 nt/bp molecular weight cut-off are optimized for the removal of low-molecular-weight contaminants such as salts, dyes, and unreacted reagents from larger oligonucleotides and proteins. Ideal for 150 µL to 1 mL samples, these spin columns support efficient desalting, buffer exchange, and sample cleanup in high-throughput molecular biology and protein workflows.
All CentriPure MINI 20 nt/bp columns are packed with Zetadex gel filtration resin and engineered for consistent centrifugation performance. Choose from pre-swollen, pre-packed formats or non-hydrated resin for flexible equilibration with your preferred buffer.
