Soxhlet extractor setup11/9/2023 ![]() ![]() This entire assembly is fitted into the neck of a round bottom flask containing the solvent. A water condenser is attached to the cylinder at the top. This cylinder is provided with a siphon tube and an inlet tube. For additional or replacement flasks see item #CG-1500. The crude substance is placed in a thimble-shaped filter paper which is then kept in a glass cylinder. Glass thimbles must be ordered separately. Complete apparatus consists of the extractor body, condenser, and 25mL round bottom flask. Extractor body has a 19/22 top inner joint and a 14/20 lower inner joint. set-up comprising: 1 each 500 ml flat-bottom flask: 150 ml extractor and. Micro size Soxhlet extractor for use with 10 x 50mm paper or glass thimbles. An identical setup with a round bottomed flask is also available (see item# CG-1369). ExtractionSerial extraction apparatus: soxhlet: accessories -Holder with. A Soxhlet Extractor or Soxhlet Apparatus is a piece of laboratory apparatus which is originally designed for the extraction of a lipid from a solid material. These extractors can be used with fritted glass thimbles ( item # CG-1372) or paper thimbles (not sold here, sorry). Three sizes are available: 50, 85, and 200 mL. The individual components are also available separately. This complete unit includes a flat-bottom flask, the extractor, and an Allihn condensor sized as shown in the picture. When the solvent in the bottom ask is heated to boiling temperature, the solvent vapor condenses in the reux condenser at the top of the setup, lling the cup of the Soxhlet extractor containing the sample. These are also great for the extraction of essential oils. Soxhlet extractor tted with a reux condenser and mounted on top of a ask containing the desired solvent. Typical uses for Soxhlet devices include extracting fullerenes from raw soot (using toluene or similar solvents) and the determination of fat content in food or feed samples (using hexane as the solvent). ![]() The cycle then repeats itself. The condenser on these units has an enlarged uptake tube to improve the condensing capacity. When the level of the condensate in the extractor rises above the inner U-shaped sidearm, it automatically siphons the solvent and dissolved material into the lower flask. The condensed solvent drips into the Soxhlet device and onto a porous glass or paper thimble containing the material to be extracted. The flask and extraction solvent are heated and the vapors rise up the outer sidearm until they reach the water-cooled condenser. It is also widely used for extracting bioactive compounds from natural resources which is crucial in environmental analysis of soils and wastes.Soxhlet extraction devices are ingenious inventions for the continuous extraction of sparingly soluble solids with a volatile solvent. The heating temperature can be adjusted according to the boiling point of the reagent and the ambient temperature. Now, the Soxhlet extractor is used whenever exhaustive extractions are needed, particularly in the oil and food industries. Automatic Soxhlet extractor consists of three major parts: heating and extraction, solvent recovery and cooling, fully automatic process operation, automatic solvent recovery, and time saving. Also, the Soxhlet extractor can run continuously without any further operation, making it an excellent choice for extracting compounds over hours or even days.įranz Ritter von Soxhlet first invented the apparatus to extract lipids (fats) from milk solids. This means that much less solvent is used in a Soxhlet extraction, making it more time and cost effective. Unlike a traditional extraction method, a small amount of solvent is reused to perform an extraction many times. ![]() 1) Stirrer bar/anti-bumping granules 2) Extraction pot (round bottom flask) 3) Distillation path 4) Soxhlet Thimble 5) Extraction solid 6) Syphon arm inlet 7) Syphon arm outlet 8) Reduction adapter 9) Condenser 10) Cooling water out 11) Cooling water in Why use it?
