Thermo Scientific™ Zeba Spin Desalting Columns (40K MWCO) contain a size-exclusion chromatography resin that provides excellent protein desalting performance in a centrifuge format for 5μL to 4mL samples.

Thermo Scientific Zeba Spin Desalting Columns, 40K MWCO, 5 mL are polypropylene devices containing a
proprietary high-performance size-exclusion chromatography resin that provides an excellent protein desalting and recovery in a centrifuge format.
Features of Zeba Spin Desalting Columns, 40K MWCO, 5 mL:
• High recovery—low-binding resin maximizes protein recovery
• Fast—no screening of fractions or waiting for protein to emerge by gravity-flow
• Easy-to-use—no cumbersome column preparation or equilibration
• Flexible—available in spin columns and filter spin plates for a range of needs

• Economical—comparable performance at lower cost than other commercially available resins
Dilute (25 µg/mL) protein samples can be successfully processed to achieve greater than 90% retention (removal) of salts and other small molecules (< 2000 MW) while maintaining and good recovery of proteins and other macromolecules (> 40,000 MW).

Available Formats:
• Spin Columns—75 µL, 0.5 mL (microcentrifuge), 2 mL, 5 mL, 10 mL columns
• 96-well Spin Plates—pre-dispensed 96-well filter plates, compatible with centrifugation for manual or automated purification. The plates enable fast, consistent well-to-well and plate-to-plate reproducibility for small-scale, high-throughput separations.
