Whelan Scientific Glass Spherical Separatory Funnel 24/40 STJ 100 ml with Side Hole Opening Lot of 2 Funnels

The Whelan Scientific Glass Spherical Separatory Funnel (100 ml) is a specialized piece of laboratory glassware designed for liquid-liquid extractions. This specific model stands out due to its spherical geometry and the inclusion of a side hole opening, which is typically used for pressure equalization or gas introduction during sensitive chemical processes. Some of the common applications include air-sensitive extractions, controlled additions, and small-scale preparative chemistry.

Core Performance Features

• Spherical Design: Unlike traditional pear-shaped funnels, the spherical body provides a different surface-area-to-volume ratio, which can be advantageous in specific organic synthesis setups or for uniform heating/cooling if placed in a bath.

• 24/40 Standard Taper Joint: The top of the funnel features a precision-ground 24/40 joint, making it compatible with a wide range of standard laboratory glassware including condensers and addition adapters.

• Side Hole Opening: This is a specialized feature often found in pressure-equalizing or Schlenk-line compatible glassware. It allows the user to introduce an inert gas (like Nitrogen or Argon) or to equalize pressure without opening the main stopper, which is critical for air-sensitive or volatile reagents.

Used, in great condition.
