2015/10/8 · The concentration of phosphate in surface and oligotrophic waters is sometimes below the detection limit of conventional analytical methods. In this work, a membrane extraction method using a hydrophilic PTFE (H-PTFE) membrane filter was developed to detect trace level phosphate. Phosphoantimonyl-molybdenum
Description Filter air and gasses, even at low differential pressures. Sartorius PTFE (Polytetrafluorethylene) Membrane Filters are permanently hydrophobic with low adsorption and excellent chemical compatibility. Choose from four pore sizes in a variety of diameters.
Waters offers Pall Life Sciences laboratory filters for sample and solvent filtration, including: HPLC sample filters in syringe filter format. Solvent filters in membrane disc format. Solvent filtration apparatus. A wide selection of membrane types and pore sizes to deliver the right lab filter for any sample type, and a broad range of device
Fluorofil™ ePTFE Membrane Cartridge Filters. Fluorofil™ cartridges are manufactured using a highly hydrophobic ePTFE membrane. The enhanced ePTFE membrane offers exceptionally high gas flow rates at low pressure differentials. Fluorofil™ cartridges are recommended for sterile gas filtration and venting applications.

2017/2/15 · The PTFE 2 membrane has a support made of non-woven polyester with almost twice the thickness of the other PTFE membranes and low porosity of 37%. Although the thickness of active layer for PTFE 3 is about three times that of PTFE 1, PTFE 3 exhibited higher MD coefficient because it had about 50% higher bulk porosity and about 14% larger pore size.
Membrane distillation (MD) is an emerging thermal-based membrane technology that has the capacity to treat a wide range of feed waters, including high salinity brines and wastewater. Compared with pressure-driven processes, MD has the following advantages: low electrical energy consumption, complete removal of non-volatile solutes and ambient operating pressures.

Biopharmaceutical. Our disposable polymeric cartridge filters are constructed from FDA approved materials carrying the CFR 21 number for biological safety and our materials of construction meet USP Class VI-121°C plastics. Designed and manufactured for robustness, our sterilising grade polymeric membrane filters are fully validated providing
2017/7/18 · This study investigated the influence of membrane property and feed water organic matter quality on the permeate flux and water quality during gravity-driven membrane (GDM) filtration. GDM filtration was continuously carried out over 500 days at hydrostatic pressure of 65 mbar in dead-end mode without any back-flushing or membrane cleaning. Three ultrafiltration (UF) membranes
