Cover glasses for microscopy 22x40 mm, No. 1 are precision coverslips made from chemically resistant borosilicate glass D 263® M of the first hydrolytic class. Measuring 22 mm by 40 mm and supplied in thickness No. 1, they provide a clear, uniform optical surface for high-quality microscopic examination of specimens. The glass offers excellent chemical resistance and dimensional stability, supporting reliable preparation of slides in routine and specialised laboratory work. These cover glasses from manufacturer Marienfeld are intended for applications in accordance with EU Regulation 2017/746 on in-vitro diagnostic medical devices (IVDR). Each unit carries the CE mark together with a batch number, ensuring full identification and traceability. Packaging comprises one ounce per hinged box, with ten ounces in the outer carton; bulk quantities of 250 ounces are available, subject to a minimum order of ten ounces. Suitable for pathology, cytology, histology and general microscopy workflows where consistent optical quality and regulatory alignment are required.

Questions about Microscope cover glasses 22x40 mm, No. 1
What is this article?
Microscope cover glasses 22x40 mm, No. 1 is the article on this page. Luminix Health distributes Marienfeld for laboratory use. It sits in Microscope slides & cover glasses, inside Microscopy & histology, in Lab instruments.
A slide is the glass a specimen sits on. A cover glass is the thin sheet over it, of a thickness the objective was designed for. A cover glass of the wrong thickness softens the image. Charged and plain slides hold sections differently.
A light microscope forms an image with glass lenses and transmitted or reflected light. A stereo microscope is the lower-magnification instrument for dissecting and for looking at a surface. Fluorescence needs a light source and filters matched to the dye. Histology is the preparation that makes a tissue readable: fixation, a cassette, a section, a stain. The objective's magnification and numerical aperture decide the resolution. The slide and the cover glass decide whether the section sits in the focal plane. Stains and dyes as substances are identified on PubChem. Papers on the methods are on PubMed.
