Product Overview

The Durapore® 0.45 μm PVDF Membrane Filter is engineered for laboratories requiring high filtration efficiency with minimal sample loss. Its hydrophilic PVDF membrane enables rapid filtration of aqueous solutions while maintaining excellent recovery of proteins and biomolecules due to its extremely low adsorption characteristics.

Unlike cellulose nitrate or nylon membranes, Durapore® PVDF offers superior durability, chemical resistance, and low extractable levels, making it suitable for critical laboratory applications where sample integrity is essential.

Key Features
