	RW0309000	Reinforced Membrane Filter	103	Add to Cart
Background Information Reinforced prefilter membranes can be used to remove contaminants from a variety of liquids and gases. The filters have a high dirt-holding capacity and a low pressure drop, which makes them ideally suited for reducing contaminant levels in advance of sterilizing-grade filters. Unlike traditional prefilter materials that contain asbestos or fiberglass, our reinforced prefilter membranes are made from non-shedding materials. These filters retain contaminants on the surface of the cellulose membrane.Features & Benefits:•Prefilter with high dirt-loading capacity for greater throughput •Non-shedding substrate will not unload fibers downstream Applications:Prefiltration Ahead of Sterilizing-Grade Filters Catalogue Number RW0309000 Chemistry Mixed Cellulose Esters (MCE)Polyester Web Filter Code RW03 Filter Color White Filter Diameter (⌀) 90 mm Filter Surface Plain Filter Type Screen filter Flow Rate 50 mL/min x cm² Material Size 100 Maximum Operating Temperature 70 °C Pore Size 0.2 µm Porosity % 75% Thickness 200 µm Wettability Hydrophilic
