consistency in current and next-generation medical devices. 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
Membrane Solution’s advanced PTFE membranes (pore size:0.03-5μm) achieve the perfect combination of high flow rate,high retention and cost-effective. Material characteristics of MS®PTFE membrane include small diffusion flow and more pores in any given area. MS®PTFE membrane for filtration including hydrophobic membrane and hydrophilic
Vyon® Sintered Porous Plastics. Our Vyon ® sintered porous plastic materials offer excellent chemical compatibility, exceptional strength and are resistant to most acids, bases, many organic chemicals and temperatures up to 110ºC (230ºF). Produced in both sintered porous polyethylene and polypropylene, materials are available in: Roll. Sheet.
Vyon® composite is a unique blend of our base porous plastics and additives or materials of interest such as carbon black. In addition, Porvair Sciences offers customers the ability to develop ‘clever’ composites. These are blends containing chemically active agents immobilised within the Vyon® structure.
Whatman PTFE membrane filters from Cytiva's business are chemically stable and inert, making them suitable for use with aggressive organic solvents, strong acids, and alkalis. Order Product. ×. Select Model. ID. Product Name. 28415319. PTFE Membrane, TE Range (TE 35), 0.2 µm pore size, 25 mm circle (50 pcs) 28415320.
A nonwoven polyester web, a PTFE membrane (0.02 micron pore size) and a sheet of paper were interwoven on a 3 inch O.D. metal core such that the polyester web and the PTFE membrane were contacted to each other only on one surface to form a roll 7 inches in diameter. The roll was heated at 210° C. for four hours in a circulating hot air oven.
The reinforcement of the hydrophobic PTFE membrane by a Polyester fleece assures the full mechanical stability of the PTFE membrane for specified applications after gamma sterilization. Midisart® BV is integrity testable. Quality Control. Each individual element is tested 100% for housing and membrane sealing during manufacture.
Pore size:13mm 0.22μm syringe filter ptfe, 100pcs FEATURE - The ptfe syringe filter withstand the autoclave process several times, hydrophobic PTFE membrane with Polypropylene(PP) housing Excellent unit-to-unit and lot-to-lot reproducibility and consistency, inlet female luer, outlet male slip luer
Air and gas sterilization make use of the hydrophobic characteristics of PTFE membranes and their ability to stop aqueous aerosols. Usual pore sizes are 0.2 μm and 0.5 μm. Sterile venting of vacuum manifolds, fermentation vessels, and sterile filtrate tanks and containers utilize PTFE 0.2 μm membranes. WTP and TE membrane ranges:
The membrane is firm enough to filter oil from the water. Polymer provider teams up with Chinese firm over sterile Porex has engineered this porous venting/filtering component using its proprietary medical-grade sintered PTFE hydrophobic membrane.
Absolute pore size ratings typically refer to the largest pore size of a membrane and it is expected that all pores will be equal to or smaller than the absolute rating. For the polycarbonate track-etch (PCTE) and polyester track-etch (PETE) membrane filters, porosity is the percent of the total surface area occupied by the pores; it typically
Choosing the right membrane is critical to the success of the liquid sterile filtration within your process. You must be sure to choose the right pore size, media material, and membrane specifications in order to optimize your yields, process economics and product viability.
