In addition, we can make the water-repellency surface of the PTFE (Polytetrafluoroethylene) hydrophilic by original processing technique . Poreflon™ hydrophilic membrane is most suitable for the filtration of the water solution. Poreflon™ Membrane is superior in weather resistance, a low dielectric characteristic like water-repellency.
2012/09/27 · A membrane of PTFE, commonly experimented as an effective solution to minimize the tissue adhesion in surgical reconstructive procedures 11–13 was used; composed of the inert biomaterial expanded, it features a microporous
2008/02/01 · Ocular patches are typical membrane-controlled reservoir systems. The drug, accompanied by carriers, is captured in a thin layer between two transparent, polymer membranes, which control the rate of the drug release ( Fig. 4 ). An annular white-coloured border is surrounding the reservoir for handling of the device.
Trace2 PTFE Membrane Syringe Filter, 25mm, 0.22μm, 100-pk Adding a syringe filtration step prior to injection not only helps to ensure more consistent and reliable results; it also helps protect delicate instruments and prolongs column life.
Aims: To evaluate the clinical efficacy of membrane tube implant made of expanded polytetrafluoroethylene (e-PTFE, Gore-Tex) membrane and silicone tube in treating refractory glaucoma. Methods: A retrospective chart review was performed on 43 eyes of 40 patients who underwent glaucoma tube shunt implant surgery using double layered e-PTFE membrane and silicone tube to
2021/02/15 · They were assembled inside a 15 cm long polytetrafluoroethylene (PTFE) tube (ID: 0.063″, OD: 1/8”, Thames Restek), in a tube-in-tube configuration, using two polyether ether ketone (PEEK) T-junctions (Upchurch) that sealed the
2021/01/27 · Membrane distillation has been successfully applied to concentrate fruit juice and herbal bioactive compounds in food and medicine, and to manage brine from gas, oil and desalination industries. Membrane distillation holds many
The permeability through a non-porous dense membrane is influenced both by the gas and the membrane properties, as well as by the thickness and diameter (i.e., area) of the membrane. In order to investigate the influence of membrane thickness on the permeability of H 2 , CO, CH 4 , ethanol, acetone and acetaldehyde, PFTE membranes were used with layer thicknesses of 10, 25, 35 and 50 µm and a
2020/11/17 · -Additional items for purchase include: A Flask Cap (glass stopper for a flask), and PTFE Joint Sleeves (used as a substitute for vacuum grease). We also sell a limited variety of membrane filters.-Each size of funnel and flask
