For damage analyses, it is advisable to compare the used grease with the fresh grease because the analysable contaminants and wear particles also remain in the latex thimble when the used grease is processed.Sourcing Guide for The Soxhlet Extractor Price: The required amount of grease is approximately 5 g. OELCHECK offers Soxhlet extraction as an individual test. The viscosity of the base oil can be determined easily. The oil type is determined using IR spectroscopy. The elements that can be detected in the base oil are fully dissolved, while solid constituents and wear particles remain in the thickener. An element analysis using ICP provides information on the sulphur content of the base oil. In particular, it is possible to perform tests on the base oil that would not be possible with the formulated grease. ![]() These two constituents can be investigated separately. What remains is the base oil used to produce the lubricating grease, including its oil-soluble additives, adhesion enhancers and other oil-like additives. ![]() The round-bottomed flask contains the solvent and the dissolved base oil. Soxhlet Extractor is equipment, which is used in chemical analysis laboratory for extraction of lipid from solid test material such as grain, food, oil. The solid component of lubricating pastes can also be analysed. This means that only pure solvent reaches the grease specimen each time.Īfter completion of the extraction process, only the thickener or the soap structure of the grease or solid lubricant, such as graphite or MoS2, is left in the latex Soxhlet thimble. Only the solvent is vaporised in this process the already extracted oil remains in the flask due to its higher boiling point. This process is repeated several times in order to extract as much oil as possible from the grease. When the extractor is full, the mixture of solvent and oil flows through an external siphon back into the round-bottomed flask. The solvent passes through the latex thimble and thins the soluble components present in the grease to the point that they separate and are able to diffuse through the latex. The liquid solvent drips back down into the Soxhlet extractor containing the grease specimen. The vapour rises up to the reflux condenser, where it condenses. The solvent is heated to boiling point in the flask. A water-cooled reflux condenser is located above the Soxhlet extractor. This latex thimble acts as a membrane through which the base oil and the solvent can diffuse, while the solid components remain behind. The thimble is made from latex to prevent entrainment of the entire specimen. The Soxhlet extractor with the extraction thimble is placed on top of the flask. It is poured into a round-bottomed flask. ![]() Separation into solids and oil also enables a thorough analysis of the type of base oil used, including its composition (mineral or synthetic), viscosity (high or low), and additive content (EP additives, antioxidants and corrosion inhibitors).Ī solvent such as n-pentane is used to extract the base oil from the fresh or used grease. After the oil has been separated from the soap, it is possible to draw conclusions about more than just the oil and thickener components of the grease. Lubricating greases usually consist of 70 to 90% oil The rest is a thickener based on a metallic soap such as a lithium, calcium, barium, aluminium or other soap, which acts like a sponge that holds the oil. However, with only minor modifications the apparatus he developed also does an excellent job of separating the base oil and thickener of a lubricating grease. ![]() The Soxhlet extractor takes its name from Professor Franz von Soxhlet (1848–1926), who originally used it to determine the fat content of dried foods.
