The present invention is in the field of polymer interlayers and multiple layer glass panels comprising polymer interlayers, and, more specifically, the present invention is in the field of wedge shaped polymer interlayers. The indirect evaporative heat exchange section includes a series of serpentine tubes, and an evaporative liquid is passed downwardly onto the indirect heat exchange section. The first period is longer than 1 ms and the first period plus the third period is longer than five times the second period. The system thereby enables sorting the selected microscopic objects.
