25 mm 0.45 µm Polycarbonate Membrane Filters (100 pcs)

Alpha Laboratories’ polycarbonate membrane filters are manufactured from polycarbonate film using track-etch technology. They have a smooth, flat surface that has a uniform capillary pore structure and a narrow pore size distribution, which enables high particle retention and visibility on the membrane surface. The high flow rates and excellent thermal and chemical resistance of track-etched polycarbonate membrane filters make them a suitable choice for precise particle detection and fractionation in many corrosive fluids. They have very low extractables, making them suitable for a wide variety of other applications including biological cell analysis, water microbiology, environmental analysis, fluid clarification, cytology, parasitology, bioassays, and epifluorescence microscopy. These polycarbonate membrane filters are supplied as 25mm diameter discs with a 0.45µm pore size and a 0.25mm membrane thickness. Water flow rate is 33ml/min/cm² and air flow rate is 7.5L/min/cm². They are equivalent to Whatman™ Nucleopore™ track-etched polycarbonate membrane filters. Alpha Laboratories’ polycarbonate membrane filters are plain, white, and supplied non-sterile in a box of 100 discs.
