Description
Pressure equalizing funnel clear ungraduated with glass stopcock provides controlled reagent transfer for sensitive reactions, liquid liquid extractions and moisture critical processes in Australian laboratories. The BORO 3.3 glass body offers excellent clarity, thermal stability and chemical resistance, supporting safe handling of acids, bases, solvents and air sensitive solutions. LabChoice Australia supplies this funnel for workflows requiring reliable pressure balancing during the addition of reactive liquids.
The integrated pressure equalizing arm prevents vacuum lock and maintains smooth flow into sealed or partially closed systems, improving safety and reaction stability. The precision ground glass stopcock delivers accurate flow regulation and secure shutoff while maintaining chemical compatibility across a wide reagent range. The ungraduated design allows unobstructed visibility of contents and supports qualitative control without reliance on volumetric markings. Material compliance with ISO 3585 and ASTM E438 Type 1 Class A standards ensures purity, dimensional accuracy and long term durability.
Widely used in organic synthesis, catalyst work, air sensitive reagent additions and controlled transfer operations, this pressure equalizing funnel integrates seamlessly into jointed glassware assemblies. Its robust construction and dependable flow control make it suitable for universities, research laboratories and industrial R&D environments where pressure stability and reagent precision are essential.
