Description
Round cover glasses Ø 20 mm are thin glass coverslips intended for microscopy and laboratory specimen preparation. With a diameter of 20 mm and a thickness range of 0,13-0,17 mm, they form a protective layer over samples placed on microscope slides. This thickness interval corresponds to the values given in the manufacturer description and is typical for cover glasses used with standard microscope objectives. Each unit is packed as 100 pieces, offering a convenient quantity for routine laboratory consumption. Available from manufacturer Witeg, these round cover glasses (Deckgläser) support specimen mounting in histology, cytology, pathology and general microscopy workflows. The circular shape suits applications and slide formats that call for round rather than square coverslips. Net weight of the pack is 0,017 kg, with the same gross weight indicated in the product data. Laboratories in research, education and diagnostics can use these cover glasses whenever a 20 mm round format with 0,13-0,17 mm thickness is required. They provide a straightforward consumable option for covering and protecting prepared samples during microscopic examination and imaging.

Questions about Cover glasses circular 20 mm
What is this article?
Cover glasses circular 20 mm 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.
