Iodine Flask
Product Code : SCL-CLE-11915
The StemAids Iodine Flask is a specialized laboratory vessel engineered for the determination of iodine values and other redox titrations where the prevention of vapor loss is critical. Featuring a unique funnel-shaped neck and a precision-ground glass stopper, this flask allows for the addition of reagents (like Potassium Iodide) through a "water seal" to ensure that volatile iodine vapors do not escape during the reaction period. Manufactured to ISO 9001:2015 standards, it is an essential instrument for Food Science, Petrochemical, and Analytical Chemistry laboratories.

Key Pedagogical & Laboratory Outcomes
- Volatility Interface: Facilitates student understanding of Vapor Pressure. The flask is designed to contain iodine (I2) which sublimes easily; learners identify how a physical liquid barrier prevents the loss of gaseous reactants.
- Redox Quantification: Enables the calculation of Iodine Value (IV) in fats and oils; learners apply the Wij's or Hanus method to calculate the degree of unsaturation in fatty acids.
- Procedural Analysis: Supports the analysis of "Quantitative Titration"; students evaluate the importance of the "water seal" technique—reagents are poured into the funnel-top and the stopper is slightly lifted to draw the liquid in, ensuring no internal gas escapes.
- Contamination Evaluation: Allows students to evaluate analytical precision; the high-quality Borosilicate 3.3 glass ensures no leaching occurs, which is vital when performing micro-analytical iodine determinations.
International Logistics & Compliance
StemAids ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade, high-protection packaging. The ground-glass stoppers and flasks are often matched and secured with plastic clips or protective mesh to prevent "freezing" or breakage during maritime transit.
- Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Conformance (CoC), and a technical guide for performing iodometric titrations.
- Durability: The thick-walled construction is designed to withstand the mild internal pressure changes that occur during exothermic redox reactions.
Direct OEM Sourcing Advantages
Procuring the StemAids Iodine Flask directly ensures vertical manufacturing control:
- Vacuum-Tight Ground Joints: Direct oversight of the diamond-grinding process ensures that the stopper and neck form a hermetic seal even without the use of grease, which could contaminate organic samples.
- Precision Funnel Geometry: We ensure the flare of the neck is wide enough to facilitate rapid reagent addition while maintaining a stable water seal.
- Direct Factory Inventory: Guaranteed availability of the standard 250ml "analytical size" used in international food testing standards (AOAC/ISO).
- Quality Assurance: Every flask is inspected for optical clarity and graduation accuracy to ensure it meets the rigorous demands of professional testing laboratories.
