June 22, 2022Ammonia nitrogen (TAN), a major pollutant in wastewater, consists of non-ionized ammonia (NH3) and ammonium ions (NH4 +), which are pH- and temperature-dependent. To determine its presence in water is important because of its harmful effects on both humans and aquatic organisms.

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.

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.
