SOXHLET EXTRACTION APPARATUS
Purpose :
soxhlet extractor is a laboratory apparatus for the extraction of lipids and other molecules from a solid sample
Scope :
Extracting the active principles from the samples.
Procedure :
• Assemble the apparatus.
• Fill the round bottom flask with solvent (n-Hexane).
• Put the thimble containing sample into extraction tube.
• Attach the extraction tube with flask containing solvent.
• Attach a condenser unit with the extraction tube and run the water.
• Fix the soxhlet apparatus on hot plate and heat the flask containing solvent.
• The solvent starts to evaporate and falls in the extraction tube after condensing.
• Continue this process till all the fat is extracted.
• Discontinue the process and take out the thimble.
• Again attach the extraction tube with flask containing solvent along with fat and condenser unit.
• Again heat the flask to recover the solvent.
• Discontinue the process and clean the extraction tube and thimble.
HEATING MANTLE
Purpose :
A heating mantle is a piece of laboratory equipment used to apply heat to containers, as an alternative to other forms of heated bath.
Scope :
Extraction of solutions and Distillation of solutions will come under this procedure.
Procedure :
• Switch on the heating mantle.
• Set the temperature.
• Place the sample in the round bottom flask.
• Higher voltages will cause it to overheat, melt the fiberglass insulation and expose the bare heating element.
• The heating mantle has an outer metal case that provides physical protection against damage to the fiberglass.
