POREX Virtek Medical PTFE membranes are 100% pure PTFE, maintaining the purity of PTFE along with its natural chemical resistance and other material benefits. Our portfolio of Medical PTFE membranes is performance tested and specifically designed for medical-surgical device applications with optimal airflow, bacterial filtration efficiency (BFE) and fluid barrier features.
PTFE membranes are hydrophobic in nature and are effective barriers for microbes and particulate matter. Hydrophilic PTFE membranes are also available. The high titer reduction and water intrusion pressures allow the membrane to repel high surface tension liquids while venting gases.
Types of membrane filter materials include polytetrafluoroethylene (PTFE), Porex® PTFE, cellulose acetate, nitrocellulose, and nylon. Compared to expanded PTFE (ePTFE), Porex® PTFE offers advantages in terms of production, performance, product range, and cost.
POREX Virtek™ sintered PTFE membrane is UL 94 V-0 and UL 746C listed, tested to meet all IP ratings, and can meet NEMA or other test standards. Robust sintered porous structure (safe to handle) Minimizes condensation and prevents the entry of dust, dirt, water and other contaminants.
Porex and Oxyphen offer PFOA-free membranes. 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
0.22 micron filter with PTFE Membrane media for Nitrogen gas filtration Features and Benefits Naturally hydrophobic PTFE membrane with excellent porosity, high flow rate; Absolute rating, filtration efficiency≥99.99%, Up to 0.01 micron in gas sterile filtration
The POREX Virtek PTFE vent/filter can be used for thousands of autoclave sterilization cycles. “Life-saving and health betterment procedures often leave patients vulnerable to HAIs, which can have a devastating emotional, financial and medical impact; at times, these infections can even lead to death,” said Michael Lei, Porex’s commercial leader for greater China.
Filtration membrane with hydrophilic PTFE membrane, ensure highly corrosive and oxidizing liquids and organic solvents. Biologically Inert, Chemically Resistant PTFE Media Uniform Pore Size Throughout Membrane for High Contaminant Retention Capacity and Flow Rates
Membrane Filters, PTFE Whatman’s range of membrane filters with advanced technical specifications are the preferred choice for a wide range of applications. The membrane filters offer accurately controlled pore size distribution and higher strength and flexibility, which ensure reproducibility and
Porex provided its Virtek venting and filtering solution made from medical-grade sintered PTFE hydrophobic membrane. A medical technology company sought to develop a new container for surgical instruments that could be used in autoclave sterilization.
The FS series gas sterilization filters have been developed to benefit from technological advances within the manufacturing of PTFE membranes. The sterile filter housing material uses 304BA Stainless Steel and the element uses HIGH FLOW TETPOR II, made by Parker Domnick Hunter. This new generation of filter sets the standard with an unrivalled combination of efficiency, flow rate and strength
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, % reflectivity, and dielectric properties that may be required for your application.
