Parts of a Rotary Evaporator and Their Functions Fat plays an important role in many foods. Place the thimble in the soxhlet extractor. It allows for unmonitored and unmanaged operation while efficiently . The solid to be extracted is placed in a porous thimble, made from hardened filter paper, and the solvent is heated so that its vapour flows past the thimble, condenses and fills the extractor with . Approximately 9 Kcal energy per gram. A Soxhlet extractor is placed between a condenser and a flask. The apparatus for Soxhlet extraction is shown in Fig. Cotton and thimble were used as filter for the extractions. PURPOSE:To extract and recover asphalt with high safety by the use of a nonchlorinated organic solvent, such as a citrus solvent by evacuating a distillation vessel, making a solvent filling space an incombustible gas atmosphere and performing solvent extraction. Soxhlet extraction for the determination of crude fat content. The method was invented in 1879 and the standard soxhlet technique is used in almost every analytical. Andrew Vinal. Its fully automated, except for filling the extraction vessel with herb, and connecting the co2 bottle. Soxhlet extraction is a simple and effective method.
