Grafco® Micro Cover Glasses: 22 x 22 mm, #2 (0.17 - 0.25 mm thickness), 1BX

Microscope cover glass is a very thin square piece of glass that is placed over a drop of liquid on a microscope slide. Because of surface tension, the liquid drop alone tends to sit in a thick dome. With a cover glass in place, the drop is flattened out, allowing the clinician to focus with high power very close to the specimen. The cover glass also confines the specimen to a single plane which reduces the amount of focusing necessary. The cover glass also protects the objective lens from immersion into the liquid. #1 cover glass is recommended for oil immersion or high resolution work. #2 is used for general applications.
