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.

The typical glass types used for life science products include:

• BOROFLOAT^® 33 borosilicate glass
• D263 family borosilicate glass

If another type of material is required for your application, please contact us.

In addition to the standard life science formats, such as:

• SBS-compliant microplate
• Microscope slide
• Coverslip formats in a range of shapes, dimensions and thicknesses

We offer our customers substrates exactly adapted to their special application. Typical thicknesses for NEXTERION^® substrates range from 0.1 mm up to 2 mm. Custom-sized products can be produced in rectangular, square or round formats. If special tolerances are required, we will be pleased to check if we can meet your requirements.

Please contact us for further information.

Applying thin-film coatings to glass substrates is another SCHOTT core competence. Production takes place in an ISO class 5 clean room environment. 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 Hydrogel and 3-D Polymer (NHS ester) and
• Streptavidin

NEXTERION^® also offers its diagnostic partners to develop a custom coating or to coat the substrates with coating chemicals developed by clients.

Please contact us for further information.

SCHOTT can offer customers the opportunity to customize their substrates with graphics, logos, company names, barcodes, reference marks, 2-D matrix codes, etc. 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 glass substrates. The markings are robust enough to withstand standard biomedical laboratory procedures.

• Laser-bonded foil method produces robust surface markings in black.
• A method of printing with hydrophobic ink can be used to produce graphics, logos and 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.

For your special marking, please contact us.

To fulfil the needs of very small substrates, SCHOTT has introduced the option of standard-sized substrates pre-scored into the final chip size. To separate at that step of the process chain, the final chip size is needed.

Advantages:

• Available with NEXTERION^® standard coatings as well as custom coatings
• Comfortable and cost-effective processing in standard size for the customer (no adaption of standard processing equipment required, e.g. spotting, hybridization)
• Cost-effective production, storage and handling by manufacturing with standard production equipment
• SCHOTT offers support for breaking equipment
