June 21, 2022Sterlitech item 0QBV94400.315 has an oleophobic treatment that is no longer compliant with the new REACH standards that went into effect in late 2020. This membrane has been replaced with a QP944U membrane, which has a REACH-compliant oleophobic coating. It’s an oleophobic ePTFE membrane laminate, with a PTFE functional layer and polyester backer material.

June 17, 2022Eight cups, three liters, one gallon? Straight water or added vitamins and electrolytes? Everybody has an opinion on what it means to be hydrated. Drinking water every day helps regulate mood, keeps the body from overheating, and supports healthy skin and digestion. But staying hydrated without consistent access to clean drinking water can be a challenge.

June 17, 2022What is a hydrophilic PCTE membrane? Polycarbonate track-etched (PCTE) membranes are characterized by durability, low protein binding, controlled porosity, and surface smoothness. PCTE membranes come in hydrophilic and hydrophobic materials, which affects the membrane “wet-ability”. Wet-ability refers to the ability of a membrane to draw water into the pore structure. Hydrophilic PCTE membranes have a high “wet-ability”, which means that the water contact angle is less than 90 degrees. As a water droplet is drawn through the membrane by capillary action, the water contact angle decreases. Hydrophilic membranes are best used for applications with aqueous solutions such as cell culturing, biological assays, and sterilization.
