Soxhlet Hot Extraction:

The new jacketed design protects the siphon from breakage and permits the extraction at the boiling point of the solvent. During extraction process the inner cup is enveloped in ascending solvent vapors.

The hot extraction process reduces time considerably. Compared with condensed solvent in the classical soxhlet method where the solvent temperature is below the boiling point, this method is faster because analytes are more soluable in hot vapor than in cold to warm solvent.It not only reduces time of extraction, but also reduces power and is very easy in handling
