Description
The Iodine Flask from Osmosis Scientific is a specialized piece of laboratory glassware engineered for the accurate determination of iodine values and complex iodometric titration workflows. Crafted from high-quality Boro 3.3 borosilicate glass, this flask delivers the chemical durability and thermal stability required for rigorous analytical environments and repeated laboratory use.
The defining feature of this flask is its integrated flared funnel top. This design allows for a liquid seal (typically a potassium iodide solution) to be maintained around the ground glass stopper, effectively preventing the escape of volatile iodine vapors—a critical factor for ensuring the precision of your results. Each flask is equipped with a precision-ground joint (available in 24/29 and 29/32 sizes) and a matching stopper to provide a leak-proof environment and maintain sample integrity.
Available in both 250 ml and 500 ml capacities, the Osmosis Scientific Iodine Flask is versatile enough for standard quality control testing as well as larger-scale analytical demands. Its robust borosilicate construction offers exceptional resistance to halogens and aggressive reagents, while its thermal properties allow it to withstand the heating and cooling cycles often required in oil, fat, and petrochemical analysis.
Specifically designed for use in food testing, pharmaceutical research, petrochemical labs, and educational facilities, this flask is built to provide reproducible data and long-term service. Its smooth, non-porous surface ensures easy cleaning and decontamination, making it a dependable choice for your most sensitive analytical applications.

Frequently Asked Questions (FAQs)
An iodine flask is specifically designed for iodometric and iodimetric titrations, iodine value determination in oils and fats, and any analytical procedure involving iodine where vapor loss must be prevented to ensure accurate results.
ASTM D-29 specifies the design and performance requirements for iodine determination flasks, ensuring they meet standards for accurate iodine number testing in oils, fats, and related products.
Yes, borosilicate 3.3 iodine flasks can tolerate gentle heating, but avoid rapid temperature changes; most iodometry and iodimetry procedures are performed at room temperature.
- Capacities: Commonly available in 100 ml, 250 ml, and 500 ml.
- Joints: Usually equipped with an interchangeable interchangeable ground glass stopper (e.g., 24/29 or 14/23 ISO joints) to provide a leak-proof and vapor-tight fit.
- Residue Removal: Iodine stains can be removed using a dilute solution of sodium thiosulfate.
- Standard Cleaning: Follow with a mild laboratory detergent and thorough rinsing with distilled water.
- Storage: Store with the stopper removed or with a strip of paper between the joint and stopper to prevent “freezing” (seizing) of the glass.
