General product information
High quality borosilicate glass – The solid foundation behind NEXTERION® Microarray Slides from SCHOTT
BOROFLOAT® 33 glass exhibits excellent chemical stability and durability. The glass provides an inert support for biomolecule immobilization, and hybridization, and does not leach alkali ions over time. For this reason, borosilicate glasses are highly suited to microarraying applications.
Flatness is an extremely important characteristic for microarray slides, as microarrays are typically printed with pins that have to come into contact with the slide surface to deposit probes. BOROFLOAT® 33 is manufactured by a float glass process to produce an exceptional flatness of ≤50 μm and a high quality surface finish. "Flatness" is defined by SCHOTT as the accumulated overall possible thickness deviation. This includes warp, intra-slide thickness deviation, and inter-slide thickness tolerance.
All uncoated and coated slides are cut to size using an innovative laser system to obtain precise, and highly accurate cut edges with no micro-cracks. A laser beam precisely heats the glass followed by a jet of cold liquid. This thermally induced tension causes a fissure in the glass. This results in the highest possible quality cut, in terms of edge quality and strength. Laser cut edges have a high strength that resists subsequent fragmentation or chipping. This helps to ensure the microarray slide surface remains free of particle contamination.
