The D263® family are borosilicate glasses produced with a down draw process by melting the purest raw materials. Different technical properties may be offered. D263® is the basic material for NEXTERION® coated and uncoated coverslips.
The manufacturing process used for this glass types results in two pristine, fire-polished surface that can be used without any additional polishing. All D263® glasses are highly chemically resistant materials with excellent transmission, low fluorescence, exceptional flatness and tight geometric properties.
D263® is manufactured using standardized processes and running a stringent quality control system. The uncoated type of this glass is available exclusively cleanroom cleaned (ISO class 5) and will be offered in standard and custom formats.
Chemical and Thermal Stability
D263® glass exhibits excellent chemical stability and durability. The glass provides an inert support for biomolecule immobilization and hybridization, and does not leach alkali ions over time.
A low coefficient of thermal expansion makes D263® glass remarkably resistant to high temperature levels. The glass is proven to stand up to high and fluctuating temperatures.
The low fluorescence of the glass offers exceptionally low background signals for all fluorescence detection methods, thereby maximizing the signal-to-background ratios.
All NEXTERION® substrates are cleaned using an automated ultrasonic cleaning line using multiple wash steps of varying pH levels, rinse steps and final drying stage.
After cleaning, the substrates will be either coated or, in the case of uncleaned substrates, packed up in plastic storage boxes which are sealed in air-tight laminated foil pouches under inert atmosphere in an ISO class 5 (Class 100) clean room. The glass may be used without any additional cleaning steps.
