D 263™ M Cover glass

D 263™ M Cover glass

D 263™ M Cover glass

D 263™ M is a clear borosilicate glass that is produced by a draw-down method. This allows for very thin thicknesses between 0.10 and 0.21 mm. D 263™ M is used as a cover glass for microscopic analyses and complies to the requirements of ISO 8255-1. The low autofluorescence and the chemical resistance are preconditions for reliable research results.

Applications

Light and fluorescence microscopy, especially in medical and biological science
