FAT DETERMINATION – SOXHLET

  • Because of commercial regulations, it is important for foods producers to be able to report fat / lipids content in their products. It is also important, in several industries, to closely monitor the fat content since it affects the quality or value of the product.
    Soxhlet extraction is one of the most commonly used methods for determination of total fat. This is mainly because it is fairly simple to use and is the officially recognized method for a wide range of fat content determinations. Nowadays improved extraction techniques tend to be more accurate and more generally applicable and can therefore often replace the old standard method for official analysis of many food materials.
  • OPSIS LiquidLINE has developed the SoxROC Extraction unit to increase the effectiveness of this process. The SoxROC is up to 5 times faster than the classical Soxhlet method with no loss in precision or accuracy, due to an effective sealed hot extraction process.

The Soxhlet Method versus the SoxROC technique

  • Franz Ritter von Soxhlet was a German agricultural chemist that invented the Soxhlet extractor in 1879. In the Soxhlet method the sample is placed in the extraction chamber, if necessary a porous thimble is used to keep the sample, where condensed solvent fills up and covers the sample. When the filling level is reached the solvent with extracted matter (fat) will siphon back into the boiling flask. All the time the sample is extracted with cold solvent. After a predefined number of fillings the extraction is considered complete. At the end of the extraction the solvent is evaporated so that the boiling flask only contains the extracted matter (fat). For fat extraction, dependent on sample type, also hydrolysis and drying might be necessary prior to the solvent extraction
  • By tradition Soxhlet is associated with solvent extraction. However, during all the years since the Soxhlet method was described several improvements have been made. Maybe the most important was when hot extraction was launched. This drastically reduced the extraction time needed.
  • The OPSIS LiquidLINE SoxROC Extraction Unit is based on Randall and Twisselmann techniques, using hot solvent and a closed system for optimal analytical conditions, still giving the same results as the classical and well accepted Soxhlet. During the first period, boiling, the thimble with sample is immersed in the boiling solvent. Thereafter a controlled volume solvent is collected in the receiver flask, thus lowering the solvent surface in the extraction cups below the thimble. Extraction continues, with the rinsing face. Hot solvent vapours surround the sample and simultaneously condensed solvent washes out any remaining extractable matters (fat).
  • At the end of the extraction the solvent is removed in a step by step process, leaving the cups with only extractable matters (fat/ lipids). The cups are dried and weighed, the percentage extractable matters (fat) is calculated.The SoxROC unit will automatically perform the different extraction steps in the method.

Benefit

After more than 25 years of experience within analysis, and with the introduction of the world’s first wireless Kjeldahl system, we are now reinventing solvent extraction. The SoxROC can be used for all common applications on the market, and meets the requirements for an automatic system including boiling, rinsing and drying. The SoxROC is also prepared for the future with several unique benefits.

Higher levels of Efficiency and Automation

The SoxROC is designed to allow fully automatic extraction of up to 6 samples simultaneously.

The SoxROC will perform the complete process of boiling, rinsing and recovery after inserting the samples. The pivoting hotplate will ensure rapid cooling afterwards.

  • Innovative batch handling saves time and reduces risk for errors. Easy to insert and manage 6 samples simultaneously. A practical tray carrier makes it easy to inspect samples before and after extraction. Same sample tray can be used both in the balance room and when inserting cups into the SoxROC.
  • A high throughput of 42 samples per day can be achieved. Up to 6 samples can be extracted simultaneously.
  • Fully automatic system with boiling, rinsing, and recovery. The pivoting hotplate separates from the cups for rapid cooling.
  • Several times faster than the classical Soxhlet method with no loss of accuracy or precision.

Saving Costs

OPSIS LiquidLINE engineers have spent considerable time to create a closed system which gives high efficiency on heating and high recovery of solvents. This makes the SoxROC a very cost efficient solution.

  • More than 90% recovery of solvents reduces costs.
  • Efficient cooling saves water costs.
  • OPSIS LiquidLINE designed sealing rings.
  • Unique two-fold sealing system with firstly manual closing and secondly pivoting hotplate. Flexible sealing with adaptive springs on all 6 positions.

  • Different lengths of standard cellulose thimbles, based on 25 and 33 mm diameter, can be used.

Operator Safety

Every care has been taken to ensure that the SoxROC is safe and can be used in a safe way by the operator. To avoid contact with solvents it is possible to add solvents inside the instrument. It is also easy to remove solvents with the flexible recovery tank.

  • Protection shield to cover cups during extraction makes it safe for the operator. Automatic sensors will stop extraction in case the protection shield is opened.
  • Closed addition of solvents by opening the top cover of the instrument. Possible to add solvent before and during extraction. Separate recovery tank with easy access on the front panel.
  • Samples and cups are removed in one step so there is no risk that solvent will drip from thimbles onto the hotplate. It also saves time when operating the instrument.
  • Main electronics is mounted in a pressurized box, ensuring that no solvent can enter and cause electric sparks. All valves close to solvents are ATEX classified. The SoxROC follows IP55 for protection against dust and liquids. Overheat temperature level is automatically adjusted to selected program temperature. Monitoring is done via two separate, redundant, safety systems.

One Integrated System

The SoxROC is easy to install in your lab. The system is small and compact with no need for additional computers, wires, or compressors.

  • One instrument with no additional requirement for computers, compressors or complex wires to be installed.
  • Recovery solvent tank inside the instrument, easy to remove when emptying solvents.

Customise

The SoxROC is built with the laboratory in mind, which means that it can be customised towards your specific applications. The OPSIS LiquidLINE range is already prepared for a variety of methods, solvents, filters and samples. The following accessories might be added to your SoxROC system.

  • Cups: The better thermal conductivity in aluminium makes it ideal for applications or scenarios when it is desirable to run the extraction at low temperatures. Aluminium cups are more durable than glass. Glass cups in Borosilicate makes it easy with visual inspection during the extraction. The SoxROC has two sizes of cups, 150 ml and 230 ml in both aluminium and glass. The 230 ml is ideal for Large Sample Volumes (LSV) and the small cups improve the usage of solvents – saving costs.
  • Thimbles You can use the most common thimbles on the market with the SoxROC. Cellulose thimbles 33×80 mm, 33×94 mm, 33×100 mm as well as 25×80 mm, 25×100 mm, 26×60 mm and 25×75 mm will all work well with the instrument.
  • Demanding Solvents The SoxROC instrument is built do withstand most solvents. However, seals and cup holders might require specific configuration for certain solvents. Standard is Viton seals but specific PTFE coated seals are recommended for certain solvents such as Acetone, Ethyl Acetate and Acetonitrile. The SoxROC filter holder is made of stainless steel which works well in most applications. However, for the above solvents, it is instead recommended to use SoxROC PTFE holders. Please consult OPSIS LiquidLINE to confirm the best configuration for your specific applications.
