Introducting Two New Application Notes:

Evaluation of Pall Metricel® Black PES membrane Filter for Legionella pneumophila and anisa by Direct Membrane Filtration Method

In the two new Application Notes we present methodology and data performed by a third-party laboratory that demonstrates Pall Metricel Black (PES) membrane has superior performance over two competitive black nitrocellulose membrane filters. Better performance is seen in the number of colonies recovered and morphology of the colonies with respect to the gridlines and colony distortion.


Legionella testing laboratories want to provide the most accurate test results to maximize public health protection. These application notes provide justification to evaluate Pall Metricel Black (PES) membrane in place of black nitrocellulose membrane.
