	AP1002500	Absorbent Pad	35	Add to Cart
Background Information Cellulose support pads are used to reinforce filters in Millipore's monitors for contamination analysis. When saturated with growth medium, they can also be used for culturing microorganisms on membranes.To increase flow rate and throughput, our woven mesh spacers can be placed between filters in a serial filtration to prevent the downstream screen filter from "blinding" the upstream filter pores. Features & Benefits•Avoid membrane damage during high pressure or fast flow conditions •Spacers enable you to combine multiple stages of filtration into a single process step, saving time Applications:Air Monitoring, Environmental Monitoring, Aerosol Contamination Monitoring Catalogue Number AP1002500 Chemistry Cellulose Fiber Filter Code AP10 Filter Color White Filter Diameter (⌀) 25 mm Filter Surface Plain Filter Type Depth filter Flow Rate 5.8 mL/min x cm² Material Size 100 Pore Size Not Applicable Wettability Hydrophilic

	PP2502500	Polypropylene Net Filter	100	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 PP2502500 Chemistry Polypropylene (PP) Filter Code PP25 Filter Color White Filter Diameter (⌀) 25 mm Filter Surface Plain Filter Type Net filter Material Size 100 Maximum Operating Temperature 100 °C Pore Size 25.0 µm Thickness 360 µm Wettability Hydrophobic
