Description
Pressure equalizing funnel is designed for precise and safe reagent addition in closed chemical systems. The sidearm helps maintain internal pressure equilibrium, reducing the risk of splashes or pressure buildup during sensitive reactions.
Its ungraduated, high-clarity body offers unobstructed visibility, making it suitable for use in complex procedures such as reflux, slow reagent dosing, titration, and synthesis in organic and pharmaceutical labs.
Equipped with a precision glass stopcock, the funnel ensures controlled liquid flow and secure integration with standard jointed glassware. Constructed from LabChoice BORO 3.3 borosilicate glass, it provides excellent resistance to thermal and chemical stress. Supplied by LabChoice Australia, this funnel is trusted for dependable performance in demanding lab environments.
