D263® Family

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, resulting in two pristine, fire-polished surface that can be used without any additional polishing. All D263® glasses are highly chemical 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 as well as in custom formats.
  • Chemical and thermal Stability
    ® glass exhibits excellent chemical stability and durability. The glass provides an inert support for biomolecule immobilisation and hybridisation, 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.
  • Fluorescence
    The low fluorescence of the glass offers exceptionally low background signals for all fluorescence detection methods, thereby maximizing the signal-to-background ratios.
  • Flatness
    Exceptional flatness, tight thickness variation.
  • Roughness
    ≤1 nm RMS
  • Cleaning
    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.
  • Packaging
    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.
