Chemistry lab professionals and students, this pressure equalizing dropping funnel is essential equipment for precise liquid additions!

The 500mL capacity is perfect for most laboratory-scale reactions, and the pressure equalizing tube allows for smooth, controlled dropping without pressure buildup.

Features standard taper 24/40 joints at both top and bottom for secure connections to your glassware setup.

The 2mm PTFE stopcock provides excellent chemical resistance and smooth operation without freezing or sticking like glass stopcocks can.

Made from high-quality borosilicate glass that's hand-blown for uniform wall thickness and annealed at 800°C for thermal shock resistance.

This means you can heat it directly in a flame and it withstands typical lab temperature variations without cracking.

The heavy-wall design adds durability for daily laboratory use.

Perfect for graduated additions in organic synthesis, titration setups, or any procedure requiring controlled liquid introduction.

The precision craftsmanship ensures reliable performance experiment after experiment.

Whether you're setting up a new lab or replacing worn equipment, this dropping funnel delivers the quality and precision that serious chemistry work demands.

The pressure equalizing feature alone makes such a difference in maintaining consistent addition rates compared to standard funnels.
