These spin desalting columns are made of low protein binding PP and are compatible with a wide range of standard laboratory instruments and consumables. They provide >95% retention of salts and other small molecules.

• Higher protein recovery
• Minimal sample dilution
• No screening fractions for protein or waiting for protein to emerge by gravity-flow
• Easy-to-use with no cumbersome column preparation or equilibration

The Zeba 7K MWCO is recommended for processing proteins >7 kDa, and the Zeba 40K MWCO for processing proteins >40 kDa.
