CentriPure 2 – Z25M Desalting Column, for 200 µL Samples

Description

CentriPure 2, a 200 µL Desalting Column

The CentriPure 2 desalting columns are pre-packed gravity-flow columns optimized for rapid desalting and buffer exchange of nucleic acids and proteins. Using size-exclusion chromatography, these columns remove low-molecular-weight substances such as salts, dyes, and unincorporated labels while retaining target macromolecules.

Features:

• Gravity-flow format
• MWCO: ~5 kDa (nucleic acids <10 bp)
• Resin: Zetadex®
• Pre-packed and ready to use
• Sold in packs of 2 or 50 columns

Applications:

• Desalting and buffer exchange of DNA, RNA, and proteins
• Removal of small molecules prior to enzymatic reactions or labeling
• Sample prep for downstream molecular biology workflows

Specifications:

• Column format: Z25M
• Sample volume: a 200 µL desalting column, for sample sizes 150-300 µL
• Flow method: gravity — no centrifuge required

CentriPure 2 columns offer consistent, high-quality purification with minimal dilution and fast processing, making them ideal for small-volume workflows.
