Family business in fourth generation Since our modest beginnings in Thuringia’s Geraberg we have continually grown and developed: Out of a small glass grinding production to an internationally operating company. After the Second World War, Paul Marienfeld set up the production in Coburg, Bavaria. In the fifties of the last century we moved to Bad Mergentheim in Baden-Wuerttemberg.

Progress After decades of growth the area for our further company’s expansion became insufficient. In the year 2000, we built our new factory in Lauda-Königshofen which is approx. 40 km south of Wuerzburg. Here we dispose about sufficient space for further growth and are well prepared for the challenges and opportunities of the future.

Microscopy & accessories

Microscopy & accessories D 263TM M Cover glass D 263™ M is a clear borosilicate glass that is produced by a draw-down method. This allows for very thin thicknesses between 0.10 and 0.21 mm. D 263™ M is used as a cover glass for microscopic analyses and complies to the requirements of ISO 8255-1. The low autofluorescence and the chemical resistance are preconditions for reliable research results.
