Fast Centrifugation Desalting for Oligonucleotides and Proteins
Desalting Centrifugation Column: MINI Formats
CentriPure MINI Desalting Centrifugation Columns provide rapid and reliable purification of oligonucleotides, nucleic acids, and proteins by removing salts, dyes, and other low molecular weight impurities. Designed for small sample volumes, these spin columns ensure high recovery, minimal non-specific binding, and compatibility with common downstream applications.
MINI Spin Columns (MWCO 10 nt/bp) — For 150 µL to 1 mL samples – ideal for short oligonucleotides and small peptides
MINI Spin Columns (MWCO 20 nt/bp) — For 150 µL to 1 mL samples – suitable for longer oligonucleotides and larger proteins
All CentriPure MINI columns are optimized for centrifugation workflows and are available in pre-swollen, pre-packed, or dry resin formats — simplifying buffer exchange and desalting across research and diagnostic workflows.
