	AN0604700	Polypropylene Prefilter	88	Add to Cart
Background Information Millipore polypropylene filters are constructed of 100% virgin polypropylene media. They are ideally suited for general clarifying and prefiltration applications including solvents, deionized water and bioburden reduction. They also provide broad thermal compatibility.The prefilters provide high particle retention, high dirt holding capacity and low pressure drop. They are designed for filtration of organic solvents, but they can also be used - once properly wetted with alcohol - for the filtration of aqueous solutions.Features & Benefits:•Compatible with aggressive solvents •Prefilters have high dirt-holding capacity Applications:General Prefiltration and Clarification, Suitable for Organic Solvents Catalogue Number AN0604700 Chemistry Polypropylene (PP) Filter Code AN06 Filter Color White Filter Diameter (⌀) 47 mm Filter Surface Plain Filter Type Depth filter Material Size 100 Maximum Differential Pressure, bar (psid) 5 bar (75 psid) Maximum Operating Temperature 90 °C Pore Size 0.6 µm Porosity % 35% Thickness 150 µm Wettability Hydrophobic
