Cytiva's Whatman™ Nuclepore™ Black Track-Etched Polycarbonate Membrane Filters

Nuclepore™ black dyed polycarbonate membrane filters by Cytiva's Whatman™ are high performance track-etched membrane filters ideally suited for applications using epiflourescence microscopy. Black membranes greatly reduce background fluorescence which results in improved micro-organism and particulate visibility. Using these membranes in combination with the epicount method rapid enumeration of viable nonviable microorganisms and particulate matter can be conducted in 30 minutes or less. Conventional culturing methods require incubation times of more than 24 hours. Polycarbonate track-etched membrane are dyed black with irgalan black . Flat smooth surface assures surface capture of microorganisms and particles . Extremely low non-specific absorption. Applications include potable ultrapure water food and dairy wine and clinical electronics. Diameters available: 2.5cm & 4.7cm. Pore Sizes Available: 0.2, 0.4 & 0.8µm.
