Parker – PF Mega Filter membranes Mega-Pure PTFE membrane filter cartridges provide unsurpassed flow rate capability. Parker’s PTFE membrane cartridge outperforms all competitive cartridges of the same rating at a ratio of 2 to 1 or greater, thus reducing the number of cartridges and housings required.

Absolute Rated PTFE Membrane Filter Cartridge TefTEC cartridge filters are constructed with naturally hydrophobic PTFE membrane and polypropylene support layers and components. The HIMA retentive PTFE membrane offers superior hydrophobicity and water intrusion resistance compared to PVDF and polypropylene membranes, and the cartridge construction offers a cost-effective alternative to all

The nucleotide sequence of the major outer membrane protein gene (omp1) was determined for three geographically distinct lymphogranuloma venereum isolates which were serologically untypeable. The three omp1 sequences were hybrids of serovars L1 and L2

Centrifugal devices can replace traditional separation techniques, such as column chromatography, preparative electrophoresis, alcohol or salt precipitation, dialysis, and gradient centrifugation, when performing the following: Pall’s centrifugal devices simplify many common nucleic acid and protein sample preparation procedures.

2015/4/13 · Novel acid–base blend membranes for application in high-temperature polymer electrolyte membrane fuel cells (HT-PEMFCs) were synthesized and characterized. The acid–base blend membranes demonstrated high thermal and excellent chemical stabilities in terms of oxidative weight loss. Small changes in the molecu
