Flat Bottom Flask
Product Code : SCL-CLE-11927
The StemAids Flat Bottom Flask (also known as a Florence Flask) is a versatile laboratory vessel engineered for the uniform heating, boiling, and storage of liquids. Its characteristic spherical body is designed to provide optimal heat distribution, while the flat base allows it to stand independently on a laboratory bench or heating plate without the need for support rings. Manufactured to ISO 1773 standards, this flask is a staple in chemical synthesis and preparation protocols.

Key Pedagogical & Laboratory Outcomes
- Thermal Interface: Facilitates student understanding of Convection Currents. The spherical body allows for uniform liquid heating; learners identify how heat is distributed from the base throughout the solution, minimizing "bumping."
- Storage Application: Enables efficient Reagent Preparation; learners apply the flask’s ability to stand independently to safely store mixed solutions or media before transfer.
- Phase Analysis: Supports the analysis of "Boiling and Distillation"; students evaluate the transition of liquids to vapors, often utilizing the flask as a boiling vessel in low-pressure distillation setups.
- Mixing Evaluation: Provides a stable platform for evaluating solute dissolution; the flat base is ideal for use with magnetic stirrers, ensuring the stir bar remains centered and efficient.
International Logistics & Compliance
StemAids ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade, high-density packaging. Flasks are nested in custom-cut, shock-absorbent cardboard or foam dividers to prevent mechanical fracture during maritime or air transit.
- Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Conformance (CoC), and Material Safety Data Sheet (MSDS).
- Durability: The Borosilicate 3.3 glass is stress-relieved in a computer-controlled lehr, ensuring the flask can withstand repeated heating cycles and sterilization without compromising structural integrity.
Direct OEM Sourcing Advantages
Procuring StemAids Flat Bottom Flasks directly ensures vertical manufacturing control:
- Base Stability: Direct oversight of the glass-forming process ensures the base is perfectly flat and the center of gravity is centralized, preventing the "wobble" common in lower-quality glassware.
- Neck Uniformity: We ensure that plain rims are fire-polished for safety and ground joints are diamond-honed for vacuum-tight seals with other apparatus.
- Direct Factory Inventory: Guaranteed availability of the full volumetric range, including large-scale 5-liter flasks for bulk institutional preparations.
- Quality Assurance: Every batch is "heat-shock tested" to ensure it meets the rigorous safety standards required for direct flame or hot-plate heating.
