Corning 2845-22 Cover Glass Square No. 1 22x22 mm 0.13-0.16 mm Thickness - Case of 1800

Corning 2845-22 Square Cover Glass, No. 1, 22x22 mm (Case of 1800)

Engineered for exacting high-resolution microscopy and critical histological diagnostics, the Corning 2845-22 No. 1 square cover glass delivers unparalleled optical clarity and dimensional precision. Manufactured from premium optical-grade glass, these coverslips are formulated to be completely free of striae, blisters, and internal refractive artifacts that could compromise microscopic imaging. The highly controlled No. 1 thickness range of 0.13 to 0.16 mm is specifically optimized to match the numerical aperture requirements of objective lenses designed with a standard 0.17 mm cover glass correction, ensuring maximum focal acuity and minimizing spherical aberration. With uniform 22 x 22 mm dimensions, these square coverslips provide ample surface area to securely seal and protect biological specimens on standard 25 x 75 mm microscope slides. The non-fogging, non-corroding surface chemistry ensures long-term archival stability for permanent slide mounts without degradation or clouding over time. Packaged in a bulk case of 1800, this precision consumable offers an exceptional, continuous supply for high-throughput pathology laboratories, clinical cytology screening, and academic core imaging facilities.

Technical Performance and Design

• Precision No. 1 Thickness (0.13-0.16 mm): Matches the strict optical tolerances required by high-magnification and oil immersion objectives, preventing focal distortion and maximizing image resolution.

• Premium Optical-Grade Glass: Eliminates autofluorescence and refractive imperfections, ensuring crystal-clear light transmission for sensitive fluorescence, phase contrast, and brightfield microscopy.

• Non-Corroding Surface Chemistry: Resists surface weathering and moisture degradation in high-humidity environments, preventing the "fogging" effect that can ruin permanently archived specimen slides.

• Uniform Precision Cut Edges: Cleanly sheared 22 x 22 mm borders prevent glass flaking and micro-shards, enhancing user safety while reducing particulate contamination on the specimen plane.

Key Benefits & Applications

• High-Resolution Microscopy: Essential for confocal, differential interference contrast (DIC), and super-resolution imaging where exact cover glass thickness dictates spatial resolution and focal quality.

• Clinical Histology and Cytology: Provides a flawless, flat barrier over stained tissue sections and cell smears, optimizing light transmission for rapid, accurate diagnostic pathology screening.

• Automated Coverslipping Compatibility: The strictly uniform dimensions and flat profile ensure seamless integration with automated coverslipping machines, eliminating jams and reducing hands-on time in high-throughput labs.

• Long-Term Specimen Archiving: The chemically stable glass matrix prevents leaching or pH shifts that could fade sensitive fluorophores or histological stains over decades of storage.
