Description
Cover glasses, rectangular, 21 x 26 mm are thin glass coverslips for specimen mounting in light microscopy. Each glass measures 21 mm by 26 mm and has a thickness of 0,13–0,17 mm, providing a uniform layer over samples on microscope slides. Supplied in a pack of 200 pieces from manufacturer Witeg, these rectangular cover glasses support routine work in histology, cytology, pathology and general life-science laboratories. The defined thickness range is compatible with standard mounting procedures and optical systems used in research and diagnostic settings. With a net weight of 0,028 kg, the pack offers a practical quantity for daily laboratory consumption. These cover glasses enable clear visualisation of stained or unstained preparations and serve as a basic consumable for educational, research and clinical microscopy workflows that require reliable rectangular coverslips of controlled size and thickness.

Questions about Cover glasses rectangular
What is this article?
Cover glasses rectangular is the article on this page. Luminix Health distributes Witeg 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.
