Marienfeld Superior™ Cover Glass

D 263® M Cover Glass for Microscopy

D 263®M is a clear borosilicate glass that is produced by a draw-down method. This permits the production of very thin glass thicknesses between 0.10 and 0.21 mm.

D 263®M is used as cover glass for microscopic analyses and complies to all requirements of ISO 8255-1. Its low autofluorescence and high chemical resistance are preconditions for reliable research results.

Due to the protective coating and outstanding quality of material it is easily separable, and therefore well-suited for automated cover slipping.

Applications: Light and fluorescence microscopy, especially in medical and biological science.

Features

High spectral transmission
Refractive index optimized for microscopes
Virtually colorless
Low autofluorescence
Excellent optical and cosmetic qualities
Good chemical resistance to environmental conditions
Long durability in archived samples
Low flatness deviations
Complies precisely with set thickness tolerances
Low alkali content enables cell growth
Good wettability on both glass surfaces
Protective coating facilitates automated glass separation in coverslippers
