Conical Flask
Product Code : SCL-CLE-11929
The StemAids Conical Flask, also known as an Erlenmeyer Flask, is one of the most versatile and essential vessels in the laboratory. Its iconic tapered body and narrow neck are specifically engineered to allow for vigorous swirling and mixing without the risk of spillage. Manufactured from Grade A Borosilicate Glass 3.3, it offers exceptional thermal resistance for heating and chemical durability for long-term reagent storage. Compliant with ISO 1773 standards, it is the primary interface for titrations, microbial cultures, and general liquid handling.

Key Pedagogical & Laboratory Outcomes
- Agitation Interface: Facilitates student understanding of Mixing Dynamics. The sloping sides prevent liquid from splashing out; learners identify the advantage of the conical shape during manual agitation compared to a beaker.
- Titration Quantification: Serves as the standard vessel for Volumetric Analysis; learners apply the flask under a burette to observe sharp color changes of indicators against the white ceramic base of a titration stand.
- Vapor Containment: Supports the analysis of "Evaporative Loss"; the narrow neck reduces the surface area at the top, allowing students to evaluate reactions with minimal loss of solvent or steam compared to open-mouth vessels.
- Microbial Evaluation: In biology, these serve as "shaker flasks" for evaluating aerobic cell cultures; the large surface-area-to-volume ratio at the base promotes gas exchange when placed on an orbital shaker.
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 partitions 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 it can withstand repeated autoclaving and direct flame heating without compromising structural integrity.
Direct OEM Sourcing Advantages
Procuring StemAids Conical Flasks directly ensures vertical manufacturing control:
- Reinforced Rims: Direct oversight ensures that the rims are heavy-duty and fire-polished, reducing the risk of chipping when stoppers are inserted or during cleaning.
- Uniform Wall Thickness: We ensure consistent glass distribution, particularly at the base and the radius of the "corner," to prevent thermal stress fractures.
- Direct Factory Inventory: Guaranteed availability of specialized variants, such as Heavy Duty flasks for industrial use or Filtering Flasks (with side-arms) for vacuum filtration.
- Quality Assurance: Every batch is "shock-tested" by transferring flasks from a 100?C environment to cold water to verify thermal integrity before shipping.
