Felix Glass manufactures precision microscope cover glass and blank microscope slides for biological laboratories, medical pathology, educational institutions, industrial microscopic inspection and research laboratories. Our microscope cover slips and glass slides are fabricated from high-transmission soda lime optical glass, with ultra-smooth polished surfaces, precisely controlled thickness and clean chamfered edges, delivering consistent optical performance for brightfield, phase contrast and fluorescence microscopy observation. Standard laboratory cover glass acts as the critical optical interface between specimen and microscope objective. Uniform flatness, low autofluorescence and controlled dimensional tolerances eliminate optical distortion, reduce stray light interference and protect biological samples during imaging. We supply standardized sizes as well as custom cut-to-size optical cover glass to meet OEM microscopy equipment and special experimental requirements. Premium soda-lime glass substrate offers excellent visible light transmission, low autofluorescence, suitable for routine microscopy and basic fluorescence observation. Standard No.1 thickness 0.13–0.17mm, consistent across each batch, matching the correction requirements of standard microscope objectives. All edges finely ground and chamfered to prevent cuts during sample preparation; avoids scratching immersion oil lenses and sample surfaces. Strictly cleaned production process, minimal surface contaminants. Compatible with aqueous mounting media, glycerin and common biological mounting agents. Polished surfaces, free of scratches, pits and bubbles within clear aperture We maintain regular stock of the most widely adopted square cover glass dimensions: 18×18mm, 20×20mm, 22×22mm, 24×24mm. These sizes are universally compatible with biological specimen slides for histology, cytology and educational labs. For special-purpose microscopic equipment, flow cell assemblies, microfluidic chips and custom optical fixtures, we provide precision CNC cutting service for rectangular, round and irregular outline optical glass sheets. Minimum dimensional tolerance ±0.1mm. Customers can select regular plastic box packaging or moisture-resistant vacuum aluminum foil packaging to prevent dust and humidity contamination during ocean shipping for overseas laboratory distributors. Multi-stage ultrasonic cleaning + dust-free drying for customers requiring ultra-low particle surface for sensitive imaging experiments. Custom printed box labels, outer carton marking, private labeling for laboratory consumable distributors worldwide. Round optical cover sheets for inverted microscopes, flow cells, and industrial microscopic inspection fixtures. Low thermal expansion borosilicate glass option for applications requiring higher temperature resistance and lower autofluorescence. Standard cover slips for tissue section mounting, pathological slide preparation in hospitals and diagnostic laboratories. Ideal for adherent cell slides, microorganism slides, brightfield and basic fluorescence cell imaging. Cost-effective consistent quality microscope slides and cover glass for biology classroom practical training. Flat optical cover sheets used as protective windows for metallurgical microscope sample observation fixtures. Custom cut thin glass as transparent top cover for lab-on-chip and microfluidic experimental devices. Optical window substrates for small bench-top microscope manufacturers and analytical instrument suppliers. Felix Glass produces laboratory optical glass sheets with full in-house processing: raw glass plate cutting, precision edge grinding & chamfering, multi-stage cleaning, dust-free inspection and final packaging. Strict batch control guarantees stable dimensional and optical consistency for long-term laboratory consumable supply partners. Our sales & engineering team supports global laboratory distributors: Full production traceability from raw glass panel to finished packaged cover glass and slides. Each glass sheet checked for scratches, air bubbles, chips and contamination before packing. Regular sampling thickness and dimension testing to maintain tight tolerance for microscopy use. We can provide sample units for laboratory quality verification before large bulk orders. Standard samples can be shipped within 3 working days. Felix Glass supplies microscope cover glass and blank microscope slides to laboratory equipment distributors, pathology suppliers, educational material vendors and instrument OEMs across North America, Europe, Southeast Asia and Australia. We support flexible order volume, mixed-size container loading and customized packaging solutions to help our partners expand their lab consumable product line. Large inventory of 18×18,20×20,22×22,24×24mm cover glass and 1×3 inch blank slides for fast order fulfillment. Produce non-standard rectangular, round thin glass sheets according to customer drawings for special instruments and experiments. Print customer brand name, part number and specification on plastic boxes and outer cartons without extra high minimum quantities. Available with moisture-proof vacuum foil packaging to prevent dampness during long ocean transit. Tell us your required cover glass sizes, quantity, preferred packaging and destination market. Our export sales team will send formal quotation with lead time and export packing details within 2 working days.Microscope Cover Glass & Glass Slides | Laboratory Optical Cover Slips for Biological Microscopy
