Soxhlet extraction is one of several sample preparation methods that can be used to transfer targeted analytes from a sample matrix into a solvent, to permit subsequent analysis. The key difference between reflux and soxhlet extraction is that reflux extraction involves only a flask and cooling above, whereas soxhlet extraction involves a specific apparatus called the soxhlet extractor.. Reflux is an analytical technique that involves the condensation of vapors and the return of the condensate to the system from which the condensate originated. Global Soxhlet Extraction Heater Market Research Report 2022. High-purity glass Soxhlet thimble sizes. Soxhlet extraction is the classic extraction technique for complex solid matrices, even though nowadays it is not widely practiced because of its disadvantages; it is time consuming (from 6 to 24 h) and solvent consuming (250–700 ml), and it applies constant heat to the flask in which the extracted pesticides remain.
