In many matrices fat is naturally encased or chemically bound. Therefore, hydrolysis is required to transform lipids into extractable forms. Hydrochloric acid disrupts cells walls, hydrolyses proteins / polysaccharides, and breaks lipid-carbohydrate bonds.

• The E-812/816 SOX guarantee an original, automated and accelerated Soxhlet extraction.
• Best solvent recovery rates thanks to solvent tank with condenser.

Yes, only when working with D-Ether (volatility) or chloroform (toxicity), working in the fume hood is necessary.

When you use a solvent like petroleum ether, a recirculating chiller should be implemented if the tap water is warmer than 15 °C. The temperature difference between the boiling point of the solvent and the cooling water temperature should be 20 - 25 °C in order to achieve a good condensation of the solvent in the condenser and to keep a good solvent recovery.

Yes, all material is resistant, solvent is drained directly from the condenser.

The refrigerant in all BUCHI recirculating chillers is R-134a (1,1,1,2-Tetrafluoroethane). This is a haloalcane refrigerant with thermodynamic properties similar to R-12 (dichlorodifluoromethane), but with less ozone depletion potential.

The mixture on the coolant is very important. If the mixture is not correct, it may freeze in the chiller and block or destroy the pump. Therefore we recommend a mixture of ethylene glycol and water 30/70 (%V). This mixture has a freezing point of -14 ° C. As the F-100 has a fix temperature of 10 °C also water is ok.
