Proton-exchange membrane fuel cells (PEMFC), also known as polymer electrolyte membrane (PEM) fuel cells, are a type of fuel cell being developed mainly for transport applications, as well as for stationary fuel-cell applications and portable fuel-cell.
prefilter and a PVDF membrane. The hydrophilic PVDF membrane provides high flow rates and throughput, low extractables and broad chemical com-patibility. This membrane binds less protein than nylon or PTFE membranes. AF6-6C06-12 100/pk AF6-6C06-52
The advanced ptfe hollow fiber membrane offered by leading suppliers are made of sturdy metals, PVDF materials that assure long term durability and sustainability along with consistent performances. These ptfe hollow fiber membrane are equipped with 12 to 24 filling heads and are loaded with unique technologies such as brackish water treatment, seawater desalination, portable water treatment.
Can be made hydrophilic by pre-wetting with IPA. 7. 28 mm diameter. 8. Additional dimensions and membrane types are available. Please contact your local Phenomenex technical consultant or distributor for availability or assistance. 9. Larger quantity
2019/9/5 · Polytetrafluoroethylene (PTFE) microfiltration membranes (pores size of 0.1 μm, Φ50 mm) were provided by Haining Yibo Filtration Equipment Factory (China). 2.2. Grafting of PVDF with 4-VP. The grafting of 4-VP on PVDF was carried out by UV photo-preactivation/ thermally-induced grafting method.
This study was conducted in thermophilic conditions with the Polytetrafluoroethylene hollow fiber (PTFE-HF) membrane which was operated at 55 C. The reactor was operated at Organic Loading Rates (OLR) of 2, 3, 4, 6, 8, and 10 kg Chemical Oxygen Demand (COD)/m3·d to investigate the treatment performance and the membrane operation.
PTFE is an inherently hydrophobic membrane, excellent for filtration of organic-based, highly acidic or basic samples and solvents. Widely used in chromatography, it is especially well suited for the clarification of non-aqueous samples. Although this membrane

The advanced expanded ptfe membrane offered by leading suppliers are made of sturdy metals, PVDF materials that assure long term durability and sustainability along with consistent performances. These expanded ptfe membrane are equipped with 12 to 24 filling heads and are loaded with unique technologies such as brackish water treatment, seawater desalination, portable water treatment.
Metals extractables limit (µg/device) Particles in DIW (≥50 nm/10 mL) PTFE membrane 17 L/min <3.5 <4; Fe and Ca <0.5; Na <1.5; all other individual metals <0.3 <25 UPE membrane 8 L/min ≤30 <30 <50 PTFE membranes of a similar nominal pore This is a
2017/11/15 · The membrane with a high selectivity for Cu 2+ separation was prepared by pressure filtering BPEI-CQD/PPy/PSS solution through a polytetrafluoroethylene (PTFE) membrane. In this ESIP system, the directional uptake/release of Cu 2+ was realized by modulating the redox state of the membrane coupling with an external electric field.
MS ® mixed cellulose ester (MCE) membrane filters are composed of cellulose acetate and cellulose nitrate. Because MCE membrane is biologically inert, it’s widely used in analytical and research applications. MCE membrane filter is characterized by smoother and more uniform surface than pure nitrocellulose filter.
Ptfe Polytetrafluoroethylene(PTFE) - Phenex-PTFE membranes are inherently hydrophobic and excellent for filtration of 100 % organic or highly acidic or basic samples. Pes Polyethersulfone(PES) - Polyethersulfone membranes exhibit very fast-flow and ultra
Phenex syringe filters are designed for efficient and rapid filtration of almost any solution prior to analysis, and are optimized for superior flow rates and high throughput. Proper membrane and size selection are the keys to choosing the best product to maintain the integrity of your sample components as well as to protect your system from
