Custom products and
coating solutions
The manufacture of special technical glasses is one of the SCHOTT group’s
core competencies. SCHOTT produces an extremely wide range of technical
glasses, including fused silica, borosilicate, and optical glasses. In addition,
SCHOTT has extensive experience in high technology glass processing, and
coating technologies. SCHOTT Microarray Solutions can take full advantage
of the extensive in-house facilities to offer customers, glass substrates in
formats tailor-made for specific life science applications. Customization may
range from simply supplying a unique barcode sequences on a standard
Nexterion® slide, to a custom coated substrate for a microfluidics application.
The production and quality control systems used for manufacturing custom
products conform to the ISO 9001-2000 standard.

Custom coatings
|
Applying thin-film coatings to glass substrates is another SCHOTT core competence.
Production takes place in a class 100 clean room environment at the
SCHOTT facility in Jena, Germany. Extremely high quality standards are maintained
for surface finish, flatness, parallelism and absence of surface defects.
The coating technologies available include:
• Dip coating
• Chemical vapor deposition (CVD)
• Sputter deposition
• Solvent based reactor method
• Spin coating
Any of the standard Nexterion® functional coatings can be applied to just
about any custom format. The coatings include:
• Aminosilane
• Aldehydesilane
• Epoxysilane
• 3-D thin film polymer-NHS ester
• Nitrocellulose
• Inorganic coatings such as gold, and other metallic coatings
SCHOTT Microarray Solutions is also able to coat glass substrates with coating
chemistries developed by clients.

Logos, fudicial marks and barcodes
|
SCHOTT can offer customers the opportunity to customize their slides and
glass substrates with graphics, logos, company names, barcodes, reference
marks, or 2-D matrix codes. These markings may be added at any location
on, or within the glass surface, and may feature a combination of items, for
example a company logo plus a sequential barcode.
SCHOTT can offer a number of methods for marking the glass substrates. The
markings are robust enough to withstand standard biomedical laboratory
procedures.
- Laser-bonded foil method produces robust surface markings in black,
or other colours.
- A method of printing with hydrophobic ink can be used to produce
graphics, logos, as well as multi-well patterns.
- Laser ablation process produces robust marks on the surface of the glass.
- Laser-induced internal marking, introduces markings by the creation of
micro-cavities within the glass.

Glass types and formats
|
The SCHOTT group produces several hundred different types of glass. The
range of glass thicknesses available is very wide, ranging from 30 µm up
to 254 mm (depending on the glass type). Substrates may be laser cut into
the final size, or partially diced to allow the later separation of individual
components.
The typical glass types used for life science products include:
BOROFLOAT® 33 borosilicate glass
D263T borosilicate glass
B270 optical glass
BK7 optical glass
Fused silica (quartz) wafers
Standard life science formats:
SBS compliant microplate
Microscope slide
Coverslip formats in a range of
shapes, dimensions, and thicknesses
Custom formats:
Rectangular
Square
Round
|
Advanced glass processing
|
Along with more traditional glass processing methods, such as cutting, grinding,
polishing and water jet cutting, SCHOTT has invested heavily in new
technologies, such as ultrasonically enhanced drilling for high precision circular
holes 400 µm up to 3 mm. Sand blasting permits the creation of round
and rectangular holes, caverns and channels, 100 µm up to 1.5 mm in glass
substrates.
