Square Coverslips, No. 1 Thickness, 18x18mm

Marienfeld Superior cover glasses feature excellent flatness and smooth surfaces, thanks to the best material. No cover glass made of soda lime glass matches the quality of Marienfeld's borosilicate glass coverslips. Even when archived for years, preparations keep their optical quality thanks to Marienfeld's noncorroding glass and the particularly low tolerance of the material thickness. Marienfeld's precise machining processes ensure that the coverslips have the exact size and that their edges are cut with high precision. All of Marienfeld's efficient processes include stringent, integrated quality control, ensuring high-quality coverslips that do not stick together.

Marienfeld's coverslips are ready for use and well suited for application in automated coverslippers. All these characteristics result in significant advantages for the user.

The coverslips are made of chemically resistant borosilicate glass D 263® M of the first hydrolytic class. They are absolutely colorless, perfectly clear, and suitable for fluorescence microscopy. They meet the requirements of EU Regulation 2017/746 on in vitro diagnostic medical devices (IVDR), with a CE-mark and batch number for comprehensive information and traceability. The thickness of the coverslips is no. 1 (0.13-0.16 mm), compliant with DIN ISO 8255.
