Description
Round cover glasses Ø 30 mm are precision glass coverslips intended for microscopy and laboratory specimen preparation. These circular coverslips measure 30 mm in diameter and maintain a uniform thickness of 0,13-0,17 mm, offering the optical clarity needed for detailed examination of mounted samples. Each pack contains 100 pieces, delivering a practical supply for high-throughput histology, cytology, cell-culture and research applications. Available from manufacturer Witeg, the coverslips protect specimens from contamination and dehydration while supporting bright-field, phase-contrast and fluorescence imaging. The larger round geometry is well suited to wider slides, culture vessels or specialised mounting formats that require broader coverage. With a net weight of 0,035 kg per pack, the product remains convenient to handle and store. Dimensional consistency across the batch promotes reproducible results in routine and advanced laboratory procedures. These cover glasses serve pathology laboratories, teaching facilities and scientific research settings that rely on accurate optical performance and reliable sample protection.

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