Description
Ready-to-Use Desalting Resin for Size-Exclusion Purification
Zetadex-25 Fine, Hydrated in PBS / 0.02% NaN₃ (Product No. TM-0130) is a pre-swollen, ready-to-use gel filtration matrix based on cross-linked dextran. This fine-grade resin is designed for rapid desalting, buffer exchange, and removal of low-molecular-weight contaminants from proteins and nucleic acids. With a dry bead diameter of 20–80 µm, Zetadex-25 Fine is ideal for applications requiring efficient separation and high resolution without the need for resin preparation.
This hydrated format, suspended in phosphate-buffered saline (PBS) with 0.02% sodium azide for microbial stability, enables convenient use in gravity-flow protocols or automated liquid chromatography systems.

Why Choose Zetadex-25 Fine, Hydrated?
Zetadex-25 Fine (hydrated) offers the same performance reliability as its dry counterpart but adds convenience for time-sensitive workflows. Pre-hydrated in PBS and stabilized with sodium azide, the gel is ideal for routine desalting, enabling consistent results and fast column setup—without the need for preparation or conditioning steps.
