Round Borosilicate Glass Coverslips, Batch Number

Marienfeld Superior D 263® M borosilicate glass circular coverslips are designed for demanding microscopy applications, especially in research, in vitro diagnostics, and fluorescence techniques. Their manufacturing using Draw-down technology guarantees a completely homogeneous, colorless surface with optimal flatness, providing ideal conditions for precise and reproducible observation.

The material used is characterized by minimal autofluorescence, which makes them especially suitable for fluorescence microscopy techniques, avoiding interference and improving signal quality. Likewise, borosilicate glass offers high chemical resistance, maintaining its stability against aggressive agents and ensuring a long service life even under intensive use conditions.

Each unit incorporates batch identification, allowing for complete product traceability, an essential aspect in regulated clinical and analytical applications. The coverslips comply with ISO 8255-1 standard and are certified for use in in vitro diagnostics according to IVD directive 98/79/EC, guaranteeing reliability and regulatory compliance.

The polished edges finish and the dimensional precision obtained through mechanized processes ensure optimal fit and safe handling. Furthermore, the surface treatment prevents adhesion between pieces, facilitating their use in automated systems and robotic platforms.

They are supplied in a format of 1,000 units per reference, distributed in 10 boxes of 100 pieces, which optimizes material management in intensive use laboratories. Available in multiple diameters, they adapt to different applications and working methodologies.

These coverslips represent a premium solution for laboratories that require maximum optical quality, chemical stability, and traceability in their analytical processes.
