Isopore Membrane Filter

32031602

NB.24

Filter Code: TTTP
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
Filter Type: 表面滤膜
