Oct 30, 2020 · The Porex Virtek PTFE helps provide sufficient airflow while protecting devices from dust and moisture. To address ongoing concerns around potentially harmful perfluorooctanoic acid (PFOA) and PFOA-related compounds, Porex, a specialist in porous polymer solutions, is offering Virtek PTFE, a 100% pure PTFE membrane, and Oxyphen’s family of track-etched membranes, which includes Unique-Mem
Filter membranes with higher porosities also have more surface area for binding or adsorption, the adhesion of particulates from a gas, liquid, or dissolved solid to the membrane surface. Types of membrane filter materials include polytetrafluoroethylene (PTFE), Porex® PTFE, cellulose acetate, nitrocellulose, and nylon.
May 16, 2019 · Porex said it designed the Virtek venting and filter component from its proprietary, medical-grade, 3D-sintered PTFE hydrophobic membrane. The filter, which is made up of particles fused together through heat and pressure, does not require supporting layers (or a scrim), unlike expanded PTFE film.
Porex® PTFE membranes are available in custom width rolls to accommodate automated assembly equipment for disposable disc filters. Standard disc thickness ranges from 0.5mm to 3.5mm, so Porex® PTFE discs are also suitable for use as column support in chromatographic separations. Typical laboratory applications include: Clarification of HPLC solvents
Feb 22, 2022 · PTFE Membrane Filter disc membrane - Membrane Solutions PTFE membrane with supporting layer polyester or polypropylene can effectively filtrate microorganism and other particulates; Membrane Solutions PTFE membrane is available in different diameters, pore size and packing depend on your quantity; can be customized to meet your application
Porex is a micro-expanded PTFE product that allows gasses to permeate but has a high barrier for liquid water. This material is perfect for vents, gas/liquid separation membranes, etc. It is not a Proton Exchange Membrane (PEM) material like Nafion and is a non-conductive insulator.
POREX® Virtek™ Medical PTFE materials and filters, used in multiple applications, are engineered for medical device functionality and reliability, and available with wide ranging capabilities in flow and filtration. These filters can be designed with optimal airflow, bacterial filtration efficiency (BFE) and fluid barrier features. POREX’s unparalleled material science, engineering and manufacturing expertise, combined with internationally recognized quality and regulatory standards and
Genuine Porex ™: Faster, better & cost-effective functional components. POREX ® Protection Vents used in sealed devices allow pressure equalization due to temperature changes and minimizes condensation while keeping dust, dirt, and liquid moisture out. Porex microporous polytetrafluoroethylene (PTFE) membrane is UL 94 V0 -
For Porex Virtek PTFE membrane, this value is 260 °C continuous. Other key characteristics: Porex Virtek PTFE membrane is an extremely versatile material that is used in numerous markets and applications. Other application-specific characteristics can include filtration efficiency, moisture vapor transmission rate, Gurley number
POREX PTFE or PE Protein Precipitation Membranes help remove contaminating lipids, salts and proteins from samples prior to LC-MS/MS and increases efficiency through elimination of time-consuming centrifugation and transfer steps. Ideal for 96 well plate applications. SPE Frits and Automation Filters Send Inquiry Get Price
Porex offers customized solutions to meet requirements of – Medical devices from hospital central vacuum systems to arterial syringes, urine bags, catheters, and surgical adhesive applicators; Media retention filters used in the production of dialysis systems, drug delivery devices like Inhalers, nebulizers, spray pumps etc. Porous plastic
Aug 21, 2015 · POREX® materials and filters are available in sheet and complex three-dimensional structures, in a wide variety of advanced porous media configurations including porous plastics, microporous PTFE, porous polymeric fiber, porous glass fiber membrane, porous composites and functionalized and bio-activated porous media.
While air can pass through the PTFE membrane to enable degassing or venting, the PTFE membrane can filter particles as small as 0.1 micron using depth filtration while resisting fluid ingress. With numerous medical and industrial approvals and certifications, Porex Virtek PTFE membrane is up to the most demanding challenges.
POREX VIRTEK® PTFE MEMBRANE Comparison to Pall® Versapor® R & Versapor® membranes If you need an alternative to the discontinued Pall ® Versapor R or Versapor ® membrane, make the switch to POREX Virtek membranes for added benefits that were not possible with Pall Versapor. The changing global healthcare environment requires
Our POREX Virtek ® reusable filters function in two ways: as a vent to allow pressure equalization during the sterilization process, and as a filter barrier to bacteria during subsequent storage. These reusable filters, comprised of sintered polytetrafluoroethylene (PTFE), are engineered and designed to withstand repeated sterilization cycles as well as deliver substantial performance, convenience, and cost savings over traditional single-use paper and textile filter materials.
