High-Recovery Gel Filtration for Oligonucleotide and Protein Desalting

Desalting Columns: Gravity flow MWCO 20 nt/bp

CentriPure Z50M columns provide rapid, gravity-based purification and desalting of proteins larger than 25 kDa and oligonucleotides longer than 20 bp. Packed with Zetadex-50 Medium resin, they enable consistent performance for downstream workflows such as oligonucleotide synthesis, PCR cleanup, and buffer exchange.

Available in a variety of formats from 1 mL to 10 mL sample capacity, these pre-filled, ready-to-use columns simplify purification without centrifugation or dialysis. Each batch is quality controlled to ensure high recovery, minimal loss, and excellent reproducibility across research, diagnostic, and production environments.

For smaller oligonucleotides and peptides, see:
