EverLUX® polyethersulfone (PES) filters are optimized for sterile filtration, prefiltration and clarification applications where exceptional capacity, low protein binding and absolute bacteria retention are required. This absolute-rated PES membrane filter is permanently hydrophilic. The EverLUX® membrane's tapered pore structure provides built-in prefiltration, allowing it to withstand higher particle loads without compromising flow rates. This extended capacity and service life can be directly translated into lower filtration costs. The EverLUX® filter is also available in discs, capsules, high-capacity UltraCap® and UltraCap® H.D. capsules.
