Bi-Directional 2 Pound Closed Loop Extractor, MK III Style - 6" Diameter

2 Pound Closed Loop Extractor, MK III Style - 6" Diameter More Safety Features and Still a Great Price! Includes parts our competitors leave out Only For Outdoor Use or Use in Laboratories Approved for Hydrocarbon Extraction Systems Designed for use with butane, or a 70% butane 30% propane blend.  Not for use with over 50% propane.   This is the bi-directional version of our 2 pound, 6" diameter extractor.   It is available as a parts kit or preassembled. Our basic extractors introduce butane at the bottom of the column until the oil laden butane returns to the base via a hose.  Many extraction practitioners like to have the option of introducing butane at the top of the column as well.  Filling from the bottom does a good job of wetting all of the plant material while filling a dry column from the top has the possibility of the butane finding an easy path and getting to the base without wetting all of the material.  Bi-directional capability allows you to wet all of the plant material
