Description
Low-stress cover glass disc 22,5 mm is a precision laboratory glass component supplied as a set of two pieces for optical and sample-handling work. The disc has a defined diameter of 22,5 mm and is characterised as spannungsarm (low-stress) cover glass, supporting clear observation and measurement where residual glass tension must be minimised. Each pack constitutes one set containing two individual discs, providing a ready-to-use quantity for routine laboratory preparation. Physical packaging data indicate a net weight of 0,05 kg and a gross weight of 0,1 kg, with compact outer dimensions suited to organised bench or store storage. The item originates from Great Britain and is offered by manufacturer Bellingham + Stanley as a straightforward consumable disc format. Intended for general laboratory use alongside microscopy, refractometric or polarimetric accessories that require small-diameter, low-stress cover glasses, the product delivers a simple dimensional specification without additional coatings or graded purity claims. The two-piece set format allows immediate replacement or parallel sample work while keeping inventory compact. Overall dimensions and mass support easy handling and integration into existing glassware workflows that call for 22,5 mm cover discs of low residual stress.

Questions about 22.5mm DISC
What is this article?
22.5mm DISC is the article on this page. Luminix Health distributes Bellingham + Stanley 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.
