Preservation of nematodes is a crucial element of research endeavors, and it
can be accomplished either temporarily or permanently. In order to conduct a rapid
examination, researchers may place a minute droplet of water onto a glass slide for
temporary observation. However, for the purpose of long-term preservation and
collection, permanent slides are requisite. Prior to studying nematodes under a
microscope for taxonomic purposes, it is necessary to first kill and fix them. This
method is particularly useful for taxonomic studies involving light, electron (SEM), or
transmission electron (TEM) microscopy.
