Our extractors are 100% hand-crafted in the USA, using USA Stainless Steel, assembled by ASME certified welders. We offer three distinct product lines to match your processing needs to specific batch sizes:


Our smallest model is the 1 pound closed-loop extraction system. This system is optimized for extractors to meet their personal needs and for smaller batch focused businesses.


Our next model is a 2 pound system. This is a wonderful starting point for a business that are either exploring processing on a commercial level or also producing smaller batches that are strain specific for commercial or personal-use.


Our biggest systems are 5 and 10 pounds. These units are perfect for the experienced extractors and businesses that are interested mass productions of strain-specific batches.


Remember, our systems use columns that are backwards-compatible with our smaller systems. This means that a 5 pound system that can be ran with an 1 or 2 pound column. This way you are never forced into only running large batches even if you have a 10 or a 5 pound system. Purchase a large system with an additional smaller sized column and tailor your extractions to your needs!
