The PTFE micro-/nanofiber composite filter was prepared on the surface of PTFE microfiber membrane by coating a very thin electrospun PTFE nanofiber membrane. The purpose of this nanofiber layer is to increase the filtration efficiency and hydrophobic properties of the composite fiber membrane, thereby improve the performance of the composite membrane.
13/2/2013 · Membranes: Expanded PTFE finds new markets. Figure 1: In depth filtration (left), particles penetrate the structure of the media and form a filter cake on the surface. In surface filtration (right), particles are collected on the surface of the membrane. Figure 2: Indicative results of comparative bag filter pressure drop of Donaldson’s ePTFE
High Performance Protection. We offer high purity filters for ultimate protection. Our high efficiency filter elements are rated up to 99.9999+ efficiency against 0.01 micron. Ideally suited for high purity compressed gas applications, these elements are available in several housing configurations and housing materials.
FAQs - FILTRATION What membrane filter pore size should I use for sterilization? Regardless of the membrane filter material, always use a 0.2 µm pore size membrane filter as the final filter for any sterilizing filtration. The 0.2 µm membranes used in Thermo
