Marienfeld

It is all about quality and precision, made in Germany.

​

Features

• high spectral transmission

• refractive index optimized for microscopes 

• virtually colorless appearance

• low autofluorescence

• excellent optical and cosmetic quality

• good chemical resistance to environmental conditions facilitates long durability in archiving samples

• low flatmess deviations

• complies precisely with the set thickness tolerances

• low alkali content enables cell growth

• good wettability on both glass surfaces

• protective coating facilitates automated separation of individual cover glasses in coverslippers

​

As authorized partner of Marienfeld coverglasses for researchers in United States, Neuvitro is the leading manufacturer among the world to providing professional coating of Marienfeld coverglasses on a variety of diameters (12mm, 18mm, 25mm for different culture plates) with the broadest coverage of coating substrates, such as PDL, PLL, PLO, Collagen, Gelatin, Laminin, Fibronectin, PDL+Laminin, PDL + Fibronectin, PLO+Laminin, PLO+Fibronectin, PDL+Laminin+Fibronectin, etc.

​

D 263® M is a clear borosilicate glass that is produced by a draw-down method. This permits the production of very thin glass thicknesses between 0.10 and 0.21 mm.

D 263® M is used as a cover glass for microscopic analyses and complies to all requirements of ISO 8255-1. Its low autofluorescence and high chemical resistance are preconditions for reliable research results.
