Isopore membranes should be handled carefully using appropriate forceps, such as Millipore forceps (Catalog No. XX6200006P). Avoid touching the membrane with fingers. Membranes should be used with the shiny side up.

General description
Filter Code: GTTP
Filter Type: Screen filter
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

I use it often to filter cells. I was just wondering if it matters which side of the filter I use? Are we supposed to use it the way they come in the box? So that the top of the filter is always used as the part to put the cell suspension on?
