Uncoated slides
Nexterion® Glass B and Glass D
|
SCHOTT provides two different types of uncoated glass slides, Nexterion®
Glass B (BOROFLOAT® 33) and D (D263T), for customers looking to apply their
own functional coatings. Both glass materials are borosilicate glasses with high
chemical resistance, excellent transmission, low fluorescence, and exceptional
flatness and were specially selected by SCHOTT Microarray Solutions as the
optimal glass types for microarray related applications. The naturally pristine
glass surfaces can be used without any additional polishing steps and all the
slides are laser cut to minimize particle contamination.

Autofluorescence Nexterion® Glass D
and Glass B vs. competitors
|
Nexterion® Glass B is a highly chemically resistant borosilicate glass that is
produced by melting the purest raw materials. The microfloat process is used
for manufacturing this glass type, resulting in a pristine, fire-polished surface
that can be used without any additional polishing.
This process allows the production of glass substrates with tight geometric
properties. In addition, the fluorescence is particularly low in the range of
Cy3™ and Cy5™ emission wavelengths (570 nm and 670 nm), making
Nexterion® glass slides the perfect substrate solution for microarray applications.
|
Nexterion® Glass D
|
Nexterion® Glass D is a high quality borosilicate glass produced by melting
the purest raw materials. It is manufactured by a special down-draw production
process that results in fire-polished surfaces that can be used without any
additional processing.
The Nexterion® Glass D production process allows SCHOTT to offer glass
substrates with extremely tight geometric properties. In addition, the fluorescence
is particularly low in the range of Cy3™ and Cy5™ emission wavelengths
(570 nm and 670 nm).
|

Three levels of cleanliness
|
Uncleaned
These slides are cleaned using deionised water and a conventional washing
system with brushes.
SCHOTT recommends uncleaned slides if the user intends to subject the slides
to a thorough cleaning procedure prior to further processing.
Ultrasonically cleaned
SCHOTT offers uncoated slides that are ultrasonically cleaned. The slides are
subjected to a 100% quality control process to validate the dimensional tolerances.
To remove all particles, debris, and surface contaminants the slides are
ultrasonically cleaned under alkaline conditions.
SCHOTT recommends ultrasonically cleaned slides if a basic cleaning procedure
is used prior to further processing.
Cleanroom cleaned
SCHOTT’s highest grade of uncoated slides are ultrasonically cleaned and
quality controlled, as detailed in the ultrasonically cleaned section above. In
addition, the slide storage boxes used to transport the slides are sealed in
protective foil pouches under an inert atmosphere in a class 100 cleanroom
environment. The slides can be used immediately from the sealed boxes
without subjecting them to a cleaning process.
Cleanroom cleaned slides are recommended if users intend to coat the slides
without carrying out any cleaning steps.
