Coated and uncoated glass substrates

Coated and uncoated glass substrates

We offer an extensive range of cleaned and coated substrates for research, diagnostics and many other life science applications.

The range includes standard products and functional coatings for DNA, protein and cell applications. We also develop bespoke formats, materials, coatings and markings for customers requiring customised solutions.

Glass substrate for diagnostics

Material

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® borosilicate glass

Standard formats include:

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

We offer substrates exactly adapted customer's special applications. Typical thicknesses for 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 evaluate your requirements.

Functional coatings

Coatings

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. Any of our functional coatings can be applied to just about any custom format. Coatings include:

  • Aminosilane
  • Aldehydesilane
  • Epoxysilane
  • 3D thin film/3D polymer (NHS ester)
  • Streptavidin

We also offer diagnostic partners with custom coating development.

Multiplex formats

Multiplex formats

Multi-well substrates allow parallel analyses of multiple biological samples against focused subsets of probes. The multi-well format permits a number of versatile assay designs such as multiplexed experiments, side-by-side comparisons or replicate experiments to be performed.

That is why we offer glass substrates partitioned by an ultra-hydrophobic patterning layer. The patterning material creates the individual wells that act as a hydrophobic barrier preventing cross contamination between the arrays. The well pattern may also serve as a registration aid for probe deposition. The hydrophobic patterning is available with most standard functional coatings.

Standard formats:

  • 16- or 48-well slide format
  • 96- or 384-well plate format

Customisation of the hydrophobic patterning can also be offered to separate the substrate into exactly the shape and number of wells your application is requires.

Glass customised marking

Markings

We offer customers the opportunity to customise their substrates with graphics, logos, company names, barcodes, reference marks, 2D 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. The markings are robust enough to withstand standard biomedical laboratory procedures.

Prescored glass diagnostic materials

Pre-scoring

To fulfil the demand of very small substrates, SCHOTT introduced the option of standard-sized substrates pre-scored into the final chip size. This solution allows  customers a comfortable and cost-effective handling in a convenient size which allows a separation at any step of the process chain. These substrates are available with all standard coatings as well as custom coatings.

Think big and we'll partner with you to make it happen.
