100pcs Pre-Sterilized Optical Glass Microscope Coverslips

100pcs Pre-Sterilized Transparent Optical Glass Microscope Coverslips

Elevate your microscopy work with this professional-grade set of 100 pre-sterilized optical glass coverslips. Precision-crafted from high-purity transparent glass, these coverslips deliver exceptional clarity for lab research, science education, clinical pathology testing, and amateur microscopic observation. Made in Mainland China.

Key Features

• Superior Optical Clarity: Manufactured from high-purity, impurity-free transparent glass that eliminates internal bubbles and light scattering, minimizing imaging distortion so you can observe fine specimen details with confidence and accuracy.
• Safe, Burr-Free Edges: Each coverslip undergoes precision cutting and multi-step edge polishing, producing smooth, safe edges that protect hands during handling and prevent scratches on your microscope lenses — helping extend the life of your optical equipment.
• Standard Uniform Thickness (0.13–0.17mm): Strict manufacturing tolerances ensure every coverslip meets the optical parameters of most conventional microscopes, eliminating focal-length deviation and saving repeated focusing time for consistent results every session.
• 5 Size Options Available: Choose from 18×18mm, 20×20mm, 22×22mm, 24×24mm, or 24×50mm to accommodate a wide range of specimens — from cell smears and tissue slices to educational demonstrations.
• Damage-Resistant Packaging: Each box contains 100 pieces housed in hard plastic packaging that guards against breakage during shipping and storage, making this set ideal for long-term bulk use in laboratories and educational institutions.

Frequently Asked Questions

Q: What sizes of microscope coverslips are included in this set?

A: You can choose from five cover glass sizes: 18×18mm, 20×20mm, 22×22mm, 24×24mm, and 24×50mm. Each box contains 100 pieces of your selected size, making it easy to stock up for different specimen types and experimental needs.

Q: Are these optical glass coverslips compatible with standard microscopes?

A: Yes. The coverslips are manufactured to a uniform thickness of 0.13–0.17mm, which aligns with the optical parameters of most conventional microscopes on the market supporting up to 500X magnification. This ensures accurate focal length and consistent, distortion-free imaging.

Q: Are the coverslips pre-sterilized and safe to use straight out of the box?

A: Yes, all 100 coverslips are pre-sterilized and ready for immediate use in laboratory, clinical, or educational settings. They are also packaged in hard plastic cases to prevent breakage during transport, so they arrive in pristine condition.
