EMD Millipore is the Life Science business of Merck KGaA, Darmstadt, Germany 		Products:   Isopore™ Polycarbonate membrane for microscopy and visual analysis

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. Isopore membranes do not stain resulting in low background interference. Clearing is not necessary for most transmitted light microscopy. Matched-weight filters are not usually required because of low, constant tar and ash weights. Isopore membranes are non-hygroscopic, which permits rapid drying and reduced sample analysis time.

We offer Cyclopore and Nuclepore polycarbonate membranes. The membranes are available in black or white color, with hydrophobic or hydrophilic surfaces, and in a range of pore sizes, diameters, and pore densities.

Polycarbonate track-etched membrane filters are made from a thin, microporous polycarbonate film material. These thin films have discrete pores that are formed through a combination of charged particle bombardment (or irradiation) and chemical etching. This process allows for increased control over the polycarbonate film membrane’s pore size and density. Pore sizes are well-defined and the membranes are biologically inert. Track-etched polycarbonate membranes are typically used for applications such as microscopy, particulate analysis, and environmental testing (air and water monitoring).
