Ground Edges 90° and 45°

The incorporation of ground edges in MENZEL Microscope slides reduces the danger of cuts and infections to laboratory personnel.


Slides with 90º edges are manufactured using a wet grinding process which results in a high quality fine ground edge. These slides are available with or without clipped corners. The standard slides are without clipped corners.
