A closed loop extractor recovers cannabinoids and terpenes from plant material by passing a liquefied hydrocarbon solvent through a packed column of biomass and capturing the resulting solution, all inside a sealed, recoverable system. Because the solvent is reclaimed rather than vented, a closed loop BHO extractor is the standard tool for producing shatter, wax, budder, badder, sauce, and live resin at consistent quality while keeping solvent loss and operator exposure low.
These systems are sized by material column capacity, commonly described in pounds, and the catalog spans roughly 1LB to 40LB. A 1LB or 5LB closed loop suits R&D, small-batch live resin, and strain trials, while 10LB to 40LB columns serve production runs. Most professional extractors use SS304 stainless steel for the columns, collection base, and solvent tank because it resists the pressures and cold temperatures of hydrocarbon work and cleans up reliably between runs.
When choosing a unit, match column volume to your typical batch weight, then look at how the system handles the rest of the cycle: jacketed columns and collection vessels for dewaxing and cold extraction, recovery tanks and pumps for fast solvent reclaim, and sight glasses and gauges for monitoring. Hydrocarbon extraction carries real safety and regulatory requirements, so plan for a compliant, properly rated room and trained operators alongside the equipment itself.
