Schott D 263® M Glass for Microscopy Cover Slips
Categories:	Ceramic; Glass; Optical
Material Notes:	The cover glass type D 263® M is a colorless borosilicate Glass which is produced by a SCHOTT specific down-draw method. It is available in different stock sheet sizes with thicknesses ranging from 0.1 mm to 0.21 mm. D 263® M is a perfect choice as cover glass for microscopic analysis and meets the requirements specified in ISO 8255-1 and DIN ISO 8255-1. The chemical composition of D 263® M ensures valid and reliable research results due to its low auto fluorescence and high chemical resistance. Application: Cover glass in microscopy for medical, biological and research work High luminous transmittance Colorless appearance Excellent cosmetic quality Easy to cut using the scribe and break method Excellent flatness Resistant to chemical attack Refractive index finely adapted to microscopes Low auto-fluorescence Easy to separate in automatic cover slippers due to protective coating Tight thickness control Resistance to environmental conditions ensure high durability Good cell growth Thickness for high-performance applications available Information provided by SCHOTT.
