Biohall Pear Shape Pressure Equalising Funnel with Glass/Rotaflow/PTFE Stopcock

The Biohall Pear Shape Pressure Equalizing Funnel is a sophisticated laboratory device designed to facilitate controlled liquid dispensing and pressure equalization in various experimental setups. The funnel’s pear-shaped design enhances its capacity and ease of use, providing a stable and ergonomic structure for handling liquids. Made from high-quality borosilicate glass 3.3, it offers superior resistance to thermal shock and chemical attack, ensuring reliable performance across a wide range of applications.

This funnel is equipped with a choice of stopcock types: a solid glass stopcock, a Rotaflow stopcock, or a PTFE (polytetrafluoroethylene) stopcock. The solid glass and Rotaflow options provide smooth and precise control over liquid flow, while the PTFE stopcock is particularly advantageous for handling aggressive or corrosive chemicals due to its superior chemical resistance and durability. 

The pressure equalizing feature of the funnel allows for smooth and consistent liquid dispensing, even when dealing with varying pressures or vacuum conditions. This is especially useful in reactions or processes requiring stable conditions. The clear borosilicate glass allows for easy monitoring of liquid levels and flow rates. Overall, the Biohall Pear Shape Pressure Equalizing Funnel is an essential tool for ensuring accurate and controlled liquid handling in complex laboratory experiments.
