Durapore® Membrane Filter, 0.22 µm Pore size, Hydrophilic PVDF, 100 mm Membrane, Merck KGaA (CAT#: STEM-L-3346-LKN)

Durapore® Membrane Filters feature high flow rates and throughput, low extractables and broad chemical compatibility. Compared with nylon, nitrocellulose or PTFE membranes, Hydrophilic Durapore membranes have much lower protein binding to minimize interaction with your sample and maximize recovery. A variety of pore sizes (both hydrophilic and hydrophobic) are available to meet a wide range of your application needs.
