Abstract: A specimen retaining method and slide apparatus for use with microscopes to view protozoans and similar organisms in liquid cultures. The slide assembly has a rigid rectangular base made of optically clear plastic, having a shallow well for holding the liquid culture, and a thin flexible coverslip of similar shape made of optically clear plastic placeable in the slide base to cover and retain the liquid. The base has a perimeter railing that holds the coverslip in place over the well and to prevent its disturbance when handled. The well is rectangular, oriented along the length of the base. Flat ledges extend inward from these railings to support the coverslip and to define the depth of the well. The well contains narrow ridges of height corresponding to the well depth with small liquid-distribution gaps along them to support the coverslip. These ridges constrain the specimen(s) in the liquid compartments.
