Filter loading into the stacked filter cassette
Loading of the stacked filter cassette with Nucleopore filters should be done in a dust-free environment. Ideal is the usage of a clean bench with laminar air flow. Since two stacked filter cassettes have been distributed to the Member States participating in this project, it is recommended to load new filters in the spare stacked filter cassette in the laboratory and to exchange the cassettes in the field therefore avoiding cross-contamination.
Figures 6 and 7 show images of the assembled and disassembled stacked filter cassette, respectively.
