SPI Pore™ Black Polycarbonate Track Etch Membrane Filters
A few words about epifluorescence microscopy
Epifluorescence microscopy allows the direct observation and total
enumeration of viable and non-viable organisms in less than 30 minutes as
compared to traditional culturing methods that may require incubation times
of up to 72 hours. Traditional culturing methods also underestimate the
total number of microorganisms in a sample due to the selective nature of
the media employed, lack of detection of non-viable microorganisms, and
failure to count microorganisms that are present as aggregates or
associated with particles. The need to count the total population of
microorganisms may be important since the presence of large numbers in some
samples may be significant, regardless of viability.
The SPI-Pore Black Polycarbonate Track Etch Membrane Filters are known
worldwide for their high quality and uniformly black background when viewed
this way.
