Fast Centrifugation Desalting for Oligonucleotides and Proteins
Desalting Centrifugation Column: MINI Formats (MWCO 10 nt/bp)
CentriPure MINI Desalting Columns with a 10 nt/bp molecular weight cut-off are ideal for the rapid removal of small molecules such as salts, dyes, and reaction byproducts from oligonucleotides and small biomolecules. Designed for sample volumes between 150 µL and 1 mL, these spin columns offer high recovery, fast processing, and compatibility with a wide range of downstream applications.
All CentriPure MINI 10 nt/bp columns are packed with Zetadex desalting resin and optimized for centrifugation workflows, offering quick and efficient buffer exchange or cleanup of oligonucleotide preparations. Whether you require dry resin for flexible equilibration or ready-to-use prehydrated formats, emp BIOTECH offers consistent performance and quality made in Berlin.
