It is still possible to recover the solvent with these extractors but an optional recovery tank is needed to recover. These smaller extractors are perfect for cooks, homeopathic medical use for a family or for small laboratory, where small extractions are needed for testing before you perform a large extraction. Many chefs will find extraction of oils from herbs are a much better way to get the flavor and aroma from a herb than actually adding stem, leaf and all to a dish. Sometimes heated water is just not enough or not desired. THE TABLE TOP TAMISIUM EXTRACTORS We consider the units small enough to move around in one piece. These units will actually fit on your table top. We do not sell these extractors for indoor use in any environment not properly set up to use any flammable solvent for extraction purposes. Because they are light weight, they do not have to be broken down to facilitate recovery of the solvent. Therefore the need for expensive valves are eliminated and the cost and process of assembly is greatly reduced. Although the extraction process is the same as above the time to set up is much less and time to recover solvent is far less. Taking from 20-120 minutes depending upon the volume of the solvent being recovered. Price range: US$ 450 to US$ 2050 for the larger one (1000ml) Delivery 3-4 weeks from purchase date. http://www.tamisiumextractors.com/tamisium-extractors.htm Anyone used these before?
