"Closed loop" refers to a system in which the entire process is done within a "closed" vessel. The solvent used to extract does not ever come in contact with the outside atmosphere. The "loop" portion refers to the recovery and reuse aspect of the system. The solvent will start inside one vessel, and then move through another containing botanical material, after which it will return back into the original vessel hence creating a "loop".
ZZKD's BHO closed loop extractor is 100% 304 stainless steel food and medical grade, dishwasher safe and solvent resistant; which makes it the perfect tool for BHO oil extraction. Glass extractors are known to crack or chip, so you can be sure of a safe hygienic extraction process with ZZKD's durable quality stainless steel extractor.
