The Dukal Corporation-9021 Cover Glass is a premium laboratory cover slip engineered to protect biological specimens and secure fluid mounts on standard microscope slides. Manufactured from high-clarity, non-corrosive glass, it ensures optimal light transmission and crisp optical clarity for microscopic analysis, histology, and cellular pathology. Featuring a standard #1 thickness (0.13 mm to 0.16 mm), this cover slip provides the ideal balance of thinness and structural integrity required for precise focal plane alignment under compound and high-magnification microscopes. Packaged in a 2 oz container, the 13mm x 17mm rectangular dimensions are suited for staging micro-samples, tissue sections, and microbiological smears across clinical diagnostic and educational laboratories.
