Description
Cover glass, borosilicate, pure white, thickness no. 1, 20 × 20 mm, square is a high-clarity microscopy coverslip manufactured from borosilicate glass 3.3. The pure-white optical quality and precise square format of 20 mm × 20 mm make these cover glasses suitable for routine bright-field, phase-contrast and fluorescence microscopy of biological and materials specimens. Thickness number 1 provides the standard thinness preferred for high-resolution objectives and oil-immersion work. Supplied in a pack of 2000 pieces from manufacturer Brand, the coverslips offer consistent flatness and chemical durability for mounting stained sections, cell cultures or particulate samples. Borosilicate glass 3.3 ensures low autofluorescence and good resistance to common mounting media and cleaning solvents. These square cover glasses are an essential consumable for histology, cytology, pathology and general laboratory microscopy workflows requiring reliable optical performance and dimensional accuracy.

Questions about Cover glass Boro water-white thick. no 1, 20 x 20 mm, square
What is this article?
Cover glass Boro water-white thick. no 1, 20 x 20 mm, square is the article on this page. Luminix Health distributes Brand 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.
