Description
Cover glasses for microscopy 24x50 mm, No. 1 are precision cover slips made from chemically resistant borosilicate glass D 263® M of the first hydrolytic class. With dimensions of 24 mm by 50 mm and No. 1 thickness, they deliver reliable optical performance for routine and specialised light microscopy. Each hinged-lid box holds 100 pieces, with 1,000 pieces supplied per outer carton, supporting efficient stock handling in busy laboratories. Produced by Marienfeld, these cover glasses are intended for applications under EU Regulation 2017/746 for in-vitro diagnostic medical devices (IVDR); they carry the CE mark and a batch number to ensure full traceability and documentation. The borosilicate glass 3.3 composition provides high chemical resistance and dimensional stability when exposed to common laboratory reagents and mounting media. Suitable for histology, cytology and general microscopy workflows, the glasses are also available in bulk quantities of up to 25,000 pieces for high-throughput environments requiring consistent quality and clear identification.
This article is part of Microscope slides & cover glasses, in Microscopy & histology.

Questions about Microscope cover glasses 24x50 mm, No. 1
What is this article?
Microscope cover glasses 24x50 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.
