Description
Product Overview
The F614500 Synthware Addition Funnel from Kemtech America is engineered for laboratory professionals who demand reliability and precision. Constructed from high‑quality PTFE and borosilicate glass, the funnel offers a generous 500 ml capacity while maintaining chemical resistance to a broad range of solvents and reagents. Its pressure‑equalizing design mitigates the risk of back‑pressure, ensuring smooth flow even when adding volatile or viscous liquids. The integrated PTFE metering stopcock, featuring a 4 mm bore, provides fine control over dispense rates, allowing users to add reagents drop‑by‑drop or in larger volumes as required.
Dimensions of the unit are compact enough for bench‑top storage yet robust enough for repeated use. The top joint conforms to a 24/40 outer standard, while the bottom joint matches a 24/40 inner configuration, guaranteeing a tight seal with compatible glassware such as flasks, beakers, and reaction vessels. The funnel’s transparent body enables easy visual monitoring of liquid levels, reducing the chance of over‑filling or spillage.
Usage
This addition funnel excels in a variety of laboratory settings, from academic research labs to industrial quality‑control environments. It is particularly suited for tasks that require controlled addition of reagents, such as titrations, catalyst introductions, and solvent exchanges. The pressure‑equalizing feature makes it safe to use with reactive gases, while the PTFE stopcock resists corrosion from strong acids, bases, and organic solvents, extending the product’s service life.
When performing sensitive syntheses, the funnel’s precise metering capability helps maintain reaction stoichiometry, improving reproducibility and yield. Its ergonomic design allows comfortable handling, even during prolonged procedures. The funnel can also be employed in educational demonstrations, providing students with a clear view of fluid dynamics and the importance of controlled addition.
