About us 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-Koenigshofen which is approx. 40 km south of Wuerzburg....

Cover glasses thickness No. 1 Marienfeld Superior cover glasses feature an excellent flatness and smooth surfaces thanks to the best material. No cover glasses made of soda lime glass match the quality of our borosilicate glass coverslips. Even when archived for years preparations keep their optical quality thanks to our noncorroding glass and the particularly low tolerance of the material thickness. Our precise machining processes make sure that our coverslips have the exact size and their edges are cut with high precision. All of our efficient processes include a stringent, integrated quality...

Precision cover glasses thickness No. 1.5H (Tol. ± 5 pm) for high performance microscopes Modern high-performance microscope objectives are designed to be used with cover glasses of a thickness of 170 pm. The quality of the cover glass, in particular the compliance with the nominal thickness, has thereby a crucial impact on the imaging quality. Variations of thickness reduce the image contrast and result in image defects, most notably in spherical aberration. We produce high-precision cover glasses with thickness No. 1.5H featuring an exceptionally accurate thickness of 170 pm ± 5 pm. This new...

Microscopy & accessories Microscopy & accessories Histofluid mounting medium Histofluid is a water-clear adhesive of acrylic resins dissolved in xylene. It hardens fast and due to its optical properties suits perfectly well for embedding microscopic preparations. Shortly after having covered a preparation it can already be examined and filed. Histofluid may also be used to firmly lock and seal bottle caps. Further advantages are: •• •• •• •• •• •• •• •• •• long storing or temperature changes do not cause fissures or deformations in Histofluid layers does not turn yellowish when being exposed...
