Soxhelet Appts 400 ml With 1 ltr Fb

The Soxhlet apparatus is a laboratory piece of equipment designed for efficient and continuous extraction of a desired compound from solid materials using a solvent. It consists of an extraction chamber where the solid sample is placed, connected via glass tubes to a heating flask holding the solvent (commonly 100 ml, 200 ml, or 400 ml chambers matched with 250 ml, 500 ml, or 1-liter flasks). A condenser sits atop the extraction chamber, cooling vaporized solvent so it condenses and drips back to wash the solid sample repeatedly. This cyclic process allows thorough extraction of compounds without need for constant solvent replenishment. The apparatus is predominantly made from borosilicate glass for thermal resistance and durability during reflux heating. Soxhlet extraction is widely used in chemical, environmental, and biological labs for isolating oils, fats, and other analytes from solids.
