Abstract

Slide for the microscopic evaluation of liquid specimens comprising a base plate, at least one evaluation chamber and a cover foil. The evaluation chambers have a specimen application zone and an evaluation area. A capillary gap is located between the evaluation zone and the cover foil. An improved slide compared to known devices was achieved by using a foil to cover the evaluation chambers and by spacers which ensure a defined thickness of the capillary gap.
