Extraction Unit E-812/E-816 Sox
![]() | Automated Extraction in Three StepsBUCHI developed a new extraction generation with the world wide unique, real class Soxhlet system! |
Technical innovations and advantages
- Unique: Automated and accelerated Soxhlet extraction
Cycle and time monitoring allows for unattended operation and best reproducibility (RSD < 1%). The optical sensor is adjustable based on the sample level. Due to the level adjustment, the cycle throughput is increased, which makes a real Soxhlet extraction fast and efficient. BUCHI is the only manufacturer that offers an automated Soxhlet extraction unit.
- Two versions
Available as a 2- and 6-place unti: performs an automated Soxhlet extraction according to standardized methods (AOAC, 64 LFBG)
- Better operating protection thanks to higher safety standards
Cooling water, level of solvent and heat source are directly monitored, the complete apparatus is specially produced to view complete tightness of joints while a protective shield provides an extra precaution.
- Operation panel
Utilize the implemented solvent library. Select the required solvent, and all parameters for extraction, rinsing, and drying are automatically defined. No time-consuming method development is necessary.
Best solvent recovery rates- insulated tank with condenser, no unpleasant odor even with petroleum ether
Flexible Viton® z-seal-system ensures absolute tightness – adapts to the flange of the beaker and Soxhlet glass chamber; tolerances are perfectly compensated for.
Highly shock-resistant beakers - even small fissures are compensated by an intelligent z-seal-system.
Solvent library - choose your solvent and respective settings are loaded. No time-consuming application work necessary.
