Ideal for epifluorescence and other microscopy applications requiring a contrasting background. The polycarbonate membrane is used to filter the sample and is then used directly for analysis. The dark membrane gives lower background fluorescence and improves the sensitivity of the test.
Black Nuclepore membranes
Membranes for use with Epifluorescence Microscopy
Nuclepore black dyed polycarbonate membranes are high performance membranes ideally suited for applications using epifluorescence microscopy. Black membranes greatly reduce background fluorescence, which results in improved microorganism and particulate visibility.
Using these membranes in combination with epifluorescence techniques, rapid enumeration of viable and non-viable microorganisms and particulate matter can be conducted in 30 minutes or less. Conventional culturing methods require incubation times of more than 24 hours. Use black track-etched membranes with epifluorescence techniques to achieve rapid, direct enumeration of microorganisms.
