Extraction Unit B-811 LSV
 | Automated Extraction in Three Steps |
Best possible preparation for environmental and residue analysis
- A variety of methods are available for each requirement:
Hot Extraction, Soxhlet Standard and Soxhlet Warm together with continuous flow procedures.
- Programmable in accordance with requirements:
Up to 50 individual programs can held in the memory
- Method tolerances:
Selection of the appropriate heating level permits different solvents with boiling points of up to 150 °C can be used.
- Reliable results:
The four heating sources operate independently of one another so in the event of a malfunction, only the affected heat source is involved and all the others continue to operate. In this way, for example, the drying of sensitive or volatile substances can be interrupted without any need to break off the parallel activities.
- Material-appropriate extraction:
By use of the equipment variation B-811 LSV, substances which are present only in trace quantities can be concentrated to a quantity exceeding the detection limit by using a large amount of sample.
- For the use of solvents with very low boiling points or in the case of high room temperatures the BUCHI Recirculating Chiller B-740 with a cooling capacity of -10 °C to 40 °C is an ideal supplement. This external circulation chiller also saves potable water in the event of a lengthy trial series.
Economical use of solvent by adjusting the optical sensor according to the sample's volume and solvent recovery.
The integrated inert gas supply avoids the oxidation of the extract during drying.
Soxhlet standard:
Official method for many extractions, e.g. fat determination.
Form an analytical point of view the unit?s inertness meets the high demands in the field of residue and trace analysis. Parts coming in contact with the media are inert (glass, PTFE, Fluorez®). No risk of contamination or memory effects !
The extraction of large sample volumes is possible. The extraction chamber is spacious enough to hold the large 41x123 mm extraction thimble as an alternative to the glass sample tube with frit (Standard) of 120 ml.
A major advantage is the easy handling of the glass parts.
Every extraction mode can be set up with three steps ? extraction, flushing and drying ? which are computer controlled guaranteeing reproducible conditions and reliable results.
Whether it?s Soxhlet extraction or hot extraction there is no need of assembly conversions. All four extraction positions are autonomously monitored and can be activated individually.
The use of solvents with boiling points up to 150°C is possible because of the high heating power of the heating elements and the optimum heat transfer.
Highly efficient sealing system: |
high degree of tightness and solvent recovery. |
The process is continually monitored and safety is guaranteed throughout the extraction process.
Up to 6 x faster than conventional soxhlet.
Optimally designed for the Rotavapor.
