Blastula Slide
Product Code : SCL-BLE-11872
The StemAids Blastula Prepared Slide is a high-fidelity biological specimen engineered for the empirical study of early embryonic development. This slide features a section of a blastula (typically from a frog/amphibian or sea urchin), capturing the critical stage where a single-layered sphere of cells surrounds a fluid-filled cavity. Manufactured to ISO 9001:2015 standards, it is an essential resource for University Biology, Embryology, and Developmental Science laboratories to quantify cellular cleavage and architectural changes in early life.

Key Pedagogical Outcomes (Bloom’s Taxonomy Alignment)
- Embryonic Interface: Facilitates student understanding of the transition from the morula (solid ball) to the blastula (hollow ball) phase.
- Structural Quantification: Enables the identification of embryonic architecture; learners apply medium-power magnification to observe the blastocoel and the surrounding layer of blastomeres.
- Developmental Analysis: Supports the analysis of "Cell Differentiation"; students evaluate the difference in size between the animal pole (smaller cells) and vegetal pole (larger, yolk-rich cells).
- Morphological Evaluation: Allows students to evaluate the precursor stage to gastrulation, identifying the structural readiness of the embryo for future tissue layer formation.
International Logistics & Compliance
StemAids ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade secure slide mailers. Each slide is individually indexed and nested in shock-absorbent cushioning to ensure zero-breakage during international transit.
- Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Conformance (CoC), and a biological datasheet detailing the specimen source.
- Durability: The specimen is chemically fixed and permanently mounted, ensuring it remains color-fast and free from deterioration for decades when stored in a standard slide cabinet.
Direct OEM Sourcing Advantages
Procuring the StemAids Blastula Prepared Slide directly ensures vertical manufacturing control:
- Optimal Sectioning: We utilize precision microtomes to ensure the section passes exactly through the center of the blastocoel, providing the most instructional view for the student.
- Vivid Differential Staining: Direct oversight of the H&E staining process ensures that the nuclei and cytoplasm are sharply contrasted, making individual cells clearly distinguishable.
- Direct Factory Inventory: Guaranteed availability of single slides or bulk classroom sets (packs of 25/50) to support synchronized laboratory sessions.
- Quality Assurance: Every batch is manually inspected by an embryologist to ensure the integrity of the blastoderm and the absence of artifacts or folding in the sectio
