The combination of elevated temperature and pressure results in faster extraction compared to other extraction technologies. This is the result of an improved mass transfer because of higher analyte solubility and enhanced penetration. An increase from normal pressure pn to p2 is thereby necessary to keep the sample in the liquid state at T2.
Concerted parallel extraction/parallel evaporation as opposed to a sequential approach increases the sample throughput and reduces the time to analysis significantly. An incoming batch of six samples is ready for the analysis after 115 minutes.
BUCHI’s unique extraction cell design is absolutely fail-safe, reliable and yields reproducible results. A lift mechanism automatically closes the cells at the push of a button. Hence, covering the sample with a filter paper is sufficient to make the sample ready for extraction.
Each position has its own inlet and outlet valve as well as individual pressure sensors. Even in case of blockage of one position cross-contamination is excluded as an integrated troubleshooting wizard automatically relieves the pressure. All other positions can be finished while the faulty position is deactivated.
The unique extraction cell design of the SpeedExtractor allows for various sample loadings. It is also possible to insert cleaning agents such as Florisil, silica gel, charcoal etc. for in-cell clean-up, or to apply different filling techniques. This significantly facilitates the classical clean-up procedures subsequent to extraction.
Yes, with the appropriate vacuum settings. For better efficiency an insulation kit is available for the Syncore® racks with 24 and 96 positions. For best results, it is recommended to use the insulation kit and the Vacuum Pump V-300 in combination with the Interface I-300/ I-300 Pro.
Yes, all relevant parts are chemically inert for a broad range of reagents.
