	TCTP02500	Isopore Membrane Filter	70	Add to Cart
Air Flow Rate 69 L/min x cm²/psi Background Information The Isopore™ membrane is a polycarbonate, track-etched screen filter recommended for all analyses in which the sample is viewed on the surface of the membrane. Isopore™ membrane offers distinct advantages for the analysis of airborne contaminants and other particles using optical or electron microscopy. The Isopore™ membrane is composed of polycarbonate film, which has a smooth, glass-like surface for clearer sample observation. The unique manufacturing process of the membrane ensures a precise pore diameter and a consistent pore size for accurate separation of samples by size. Matched-weight filters are not usually required because of low, constant tar and ash weights.Features & Benefits:•Membrane structure retains particles on the surface, simplifying counting and analysis •Isopore™ membranes do not stain, resulting in low background interference •Non-hygroscopic, allowing for rapid drying and reduced sample analysis time •Translucent material does not require clearing for transmitted light microscopy; also available in brown variety Applications:Air Monitoring, Epifluorescent Microscopy, Chemotaxis Assays Catalogue Number TCTP02500 Chemistry Polycarbonate (PC) Diameter Biological Information Media Filter Code TCTP Filter Color White Filter Diameter (⌀) 25 mm Filter Surface Plain Filter Type Screen filter Flow Rate 69 L/min x cm²/psi Gravimetric Extractables < 1% Material Size polycarbonate, Hydrophilic, 10 µm, 25 mm, white, plain, 100 Maximum Operating Temperature 140 °C (possible reduction in flow rates may occur after autoclaving) Media Isopore® Pore Size 10.0 µm Porosity % 5%–20% Thickness 16 µm Trade Name Isopore Wettability Hydrophilic
