Coverslip | Cover Glass (Pack of 10g)
Product Code : SCL-BLE-11869
The StemAids Precision Coverslips are ultra-thin, high-transparency glass plates engineered to protect specimens and optimize optical paths during microscopic examination. These coverslips are manufactured from chemically resistant borosilicate or soda-lime glass, ensuring minimal refractive distortion. Sold in 10g packs for institutional efficiency, they are an essential consumable for biology, histology, and pathology laboratories where high-resolution imaging and specimen preservation are paramount.

Key Pedagogical & Functional Outcomes
- Refractive Index Interface: Facilitates high-resolution imaging by providing a flat, uniform surface that matches the refractive index of immersion oil and objectives, minimizing spherical aberration.
- Specimen Preservation: Acts as a physical barrier that protects the microscope's objective lens from contact with wet samples or corrosive stains, extending the life of expensive optical hardware.
- Fluid Dynamics Management: Enables the "wet mount" technique; learners apply a coverslip to a drop of pond water to flatten the sample into a single focal plane, allowing for easier tracking of motile microorganisms.
- Artifact Reduction Analysis: Supports the analysis of "Bubble Interference"; students evaluate the importance of the 45-degree placement technique to ensure a clear, bubble-free field of view for high-power microscopy.
International Logistics & Compliance
StemAids ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade bulk packaging. The 10g boxes are vacuum-sealed with silica gel desiccant to prevent "glass sticking" caused by humidity during maritime transit.
- Documentation: Includes Manufacturer’s Authorization Form (MAF) and Certificate of Conformance (CoC) verifying the precise thickness grade.
- Durability: Chemically stable glass resists fogging and oxidation, ensuring a shelf-life of several years when stored in a cool, dry environment.
Direct OEM Sourcing Advantages
Procuring StemAids Coverslips directly ensures vertical manufacturing control:
- Zero-Alkali Leaching: Our glass is processed to prevent alkali release, which can alter the pH of sensitive biological samples or interfere with specific histochemical stains.
- Uniform Thickness Control: Direct oversight of the drawing process ensures that the "No. 1.5" thickness is strictly maintained—crucial for high-end digital imaging and confocal microscopy.
- Institutional Scalability: Guaranteed availability of bulk carton quantities for university-wide procurement, ensuring a consistent supply for large student cohorts.
- Quality Inspection: Every batch is inspected for "flatness" and the absence of striations or inclusions that could distort the image under 1000x magnification.
