Separatory funnels are used in liquid-liquid extractions.

Dropping funnels are similar in shape and design, and may be used as separatory funnels.

These images are often painted on ceramic forms in the shape of laboratory vessels such as separatory funnels suspended from metal clamps.

Separatory funnels are pear-shaped, have a cap and a short neck, with a stopcock for the even pouring of fluids.

Stopcocks are often parts of laboratory glassware such as burettes, separatory funnels, Schlenk flasks, and columns used for column chromatography.

The stopper joints of chemical bottles, volumetric flasks, and separatory funnels often do not use the precision standard taper joints.

The bodies of Kolodziejski's vessels range from traditional forms such as teapots, urns, and tureens to adaptations of laboratory items such as beakers and separatory funnels.
