Premium Quality and Manufacturing Features

• No. 2 Thickness Standard: Manufactured to precise No. 2 thickness specification (0.17-0.25mm), the optimal thickness for most routine microscopy applications, providing the correct optical path length for high-resolution imaging with standard microscope objectives while maintaining adequate strength for handling
• 22mm x 22mm Square Dimensions: Standard square format provides versatile coverage for most microscope slide applications, accommodating diverse specimen sizes while ensuring compatibility with standard 25mm x 75mm microscope slides and automated slide processing equipment
• Precleaned and Ready to Use: Factory precleaned to remove manufacturing residues, oils, and contaminants, arriving ready for immediate use without additional cleaning steps, saving laboratory time and ensuring consistent specimen quality across all preparations
• Free from Optical Defects: Manufactured free from striations, bubbles, scratches, oily films, and fingerprints that could interfere with microscopic examination, ensuring clear, unobstructed views of specimens and preventing artifacts that could compromise diagnostic accuracy
• Precision-Ground Straight Edges: All four edges are precision-ground to create perfectly straight, smooth edges that prevent chipping during handling, facilitate neat specimen mounting, and provide professional appearance for permanent slide preparations
• Uniform Thinness: Consistent thickness across the entire cover glass surface ensures even specimen compression, uniform staining penetration, and predictable optical properties that support reproducible imaging results and accurate measurements
• Superior Flatness: Exceptional flatness eliminates warpage that could create air gaps between cover glass and specimen, preventing optical distortions, ensuring proper specimen contact, and maintaining consistent focal planes during microscopic examination
• Superior Clarity: High-quality glass composition provides exceptional optical transparency across the visible spectrum, ensuring true color representation, maximum light transmission, and minimal optical aberrations for accurate specimen visualization
• Corrosion Resistance: Manufactured from corrosion-resistant glass that withstands exposure to mounting media, staining solutions, immersion oils, and cleaning agents without degradation, ensuring long-term specimen preservation and archival stability
• Latex-Free Material: Not made with natural rubber latex, ensuring safe use in laboratories serving individuals with latex allergies and preventing latex contamination of sensitive specimens or reagents

Comprehensive Laboratory Applications

Essential for clinical pathology slide preparation, histology and tissue sectioning, hematology blood smears, cytology specimen mounting, microbiology wet mounts and cultures, parasitology examinations, urinalysis sediment analysis, research microscopy, educational laboratory exercises, quality control slide preparation, permanent specimen archiving, immunohistochemistry procedures, fluorescence microscopy, phase contrast microscopy, and any application requiring high-quality cover glass for optimal specimen visualization and preservation.

Clinical Pathology and Diagnostics

In clinical laboratories, these cover glasses support accurate diagnostic work by providing the optical clarity necessary to identify cellular abnormalities, microorganisms, parasites, and tissue pathology. The uniform thickness ensures consistent staining results across specimens, while the superior flatness prevents air bubbles that could obscure diagnostic features. The precleaned surface eliminates contaminants that could interfere with staining protocols or create artifacts mimicking pathological findings, supporting confident diagnostic decisions.

Histology and Tissue Processing

Histology laboratories benefit from the precision-ground edges that create neat, professional-appearing permanent slides suitable for long-term archiving and legal documentation. The corrosion-resistant glass withstands exposure to xylene, alcohols, and mounting media used in tissue processing without clouding or degradation. The superior flatness ensures tissue sections remain in a single focal plane, facilitating rapid scanning and accurate morphological assessment of tissue architecture.

Research Microscopy Excellence

Research applications demand the exceptional optical quality these cover glasses provide. The freedom from striations and optical defects ensures artifacts don't compromise experimental results or publication-quality imaging. The uniform thickness supports reproducible quantitative measurements, while the superior clarity enables accurate fluorescence microscopy, phase contrast imaging, and advanced microscopy techniques requiring optimal optical performance.

Educational Laboratory Use

Educational institutions appreciate the cost-effective quality that allows students to prepare professional-grade microscope slides while learning proper laboratory techniques. The precleaned surface simplifies slide preparation for beginning students, while the durable construction withstands the handling associated with educational settings. The standard 22mm x 22mm size is ideal for teaching basic microscopy skills and specimen preparation techniques.

Convenient Bulk Packaging

Packaged in convenient 1-ounce units with 10 packs per box, this packaging format balances accessibility with protection, allowing laboratories to maintain adequate inventory while minimizing storage space requirements. The multi-pack format supports efficient inventory management for high-volume laboratories while providing cost-effective pricing through bulk purchasing. Individual pack units facilitate distribution to multiple workstations or users without exposing the entire inventory to contamination.

Specimen Preservation and Archiving

The corrosion-resistant glass composition ensures permanent slides remain optically clear for decades, supporting long-term specimen archiving requirements in pathology departments, research institutions, and teaching collections. The superior flatness prevents specimen deterioration from air exposure, while the precision edges create professional-appearing slides suitable for legal documentation, publication, and reference collections. Properly prepared slides using these cover glasses can remain diagnostically useful for generations.

Compatibility and Versatility

The standard 22mm x 22mm square format ensures compatibility with automated slide staining equipment, coverslipping machines, and digital slide scanning systems used in modern laboratories. The No. 2 thickness works optimally with standard microscope objectives from 4x to 100x magnification, including oil immersion lenses. The square shape provides adequate coverage for most specimen types while allowing efficient use of expensive reagents and mounting media.

Quality Control and Consistency

Manufactured under rigorous quality control standards, these cover glasses provide batch-to-batch consistency that supports reproducible laboratory results and standardized protocols. The uniform optical properties ensure consistent imaging across different microscopes and operators, while the predictable dimensions facilitate automated processing and robotic handling in high-throughput laboratories. This consistency is critical for quality assurance programs and regulatory compliance in clinical settings.

Cost-Effective Laboratory Supply

The precleaned format eliminates the labor costs and time associated with manual cover glass cleaning, while the durable construction reduces breakage and waste. The bulk packaging provides excellent value for high-volume laboratories, reducing per-unit costs and minimizing reordering frequency. The superior quality reduces the need to repeat preparations due to optical defects or contamination, improving overall laboratory efficiency and reducing reagent waste.

FSA/HSA Eligible

This laboratory supply qualifies for purchase using Flexible Spending Account (FSA) and Health Savings Account (HSA) funds, making essential microscopy supplies more affordable for research institutions, educational facilities, and clinical laboratories managing supply budgets.

Storage and Handling

Store cover glasses in original packaging in a clean, dry environment away from dust, chemicals, and temperature extremes to maintain precleaned surface quality. Handle by edges only to prevent fingerprints on optical surfaces. Use immediately after removing from packaging to minimize dust accumulation. Proper storage and handling preserve the precleaned quality and ensure optimal specimen preparation results.
