Thermo Scientific Zeba Spin Desalting Columns and Plates
Overview
The Thermo Scientific Zeba Spin Desalting Columns and Plates are designed for rapid desalting and buffer exchange of protein samples using a centrifuge-based format. The A57762 configuration contains 25 spin columns with a 2 mL resin bed volume suitable for processing sample volumes from 300 to 800 µL. The proprietary size-exclusion chromatography resin is intended for proteins and macromolecules greater than 40 kDa while removing low molecular weight contaminants below 2 kDa. The polypropylene spin-column format supports efficient sample recovery with minimal dilution during processing.
