A filtration method involving a membrane filter for the collection and subsequent microscopic examination of weighed, treated samples is presented. The filter and the sample collected upon it are both mounted for microscopic examination. The filter permits sufficient light passage for identification of spores and pollen upon its surface. This method permits a more accurate transfer of weighed samples from centrifuge tubes to microscope slides.
