We believe it’s better to buy everything you need in one shot, so we’ve created a package that includes a vacuum chamber, vacuum pumps, and complete extraction system. The best part? Buying this kit will save you money compared to purchasing each component individually

Closed Loop Extraction Process

The 1lb closed loop hydrocarbon extraction system performs botanical extraction within a sealed, vacuumed system. Utilizing a top-fill input, solvent washes thru the material column, collecting oils as it passes over the material. The oil-bearing solvent is collected in the collection base under the material column. Once collected, the solvent is distilled and recovered, leaving the oils in the collection base. This is a passive unit that utilizes pressure differences created by manipulating temperature to move solvent.





Extractor Configuration:

  • Explorer: Our standard, most economical setup, perfect for the entry level extractor on a budget.  Comes with a welded bottom base and standard LP tank.  This model has minimal features to keep cost low, while providing the necessary equipment to get the job done.



  • Professional: This model features upgrades to help produce a higher quality extract.  Solvent is input into the material column with a showerhead endcap, ensuring the full material column is saturated with solvent.  The Professional comes with a sleeved spool, allowing users to utilize dry ice to freeze the material column. This will help lock in fats and waxes to the material. An inline ball valve is used to allow solvent to be suspended in the material column, as well as closing the collection base off during recovery.  Upon completion of the run, extract removal is made simple by adding a removable bottom to the collection base.



  • Elite:  The Elite series is the premium version of the Professional.  It features all American made instrumentation valves by SSP, an AVCO ultra-low temperature inline ball valve, jacketed collection base, and all high-pressure clamps.  The jacketed collection gives precision during recovery, allowing a heated fluid to be circulated around the base.  This method keeps temperature both accurate and consistent.  The elite series adds a level of dependability needed for those seeking to produce the highest quality extracts.  *NOTE* This model requires a heater circulator or chiller

*Note:  Column capacity may vary depending on the density of packed material and packing density. Capacity is calculated using the industry standard of 4.2g/in3. This is the upper limit for column capacity.  Low density, uncut, and/or lightly packed material can reduce capacity by 50%. For best results, we recommend to tightly pack coarse ground material.
