SPExtR-5G Vacuum Extraction System

Nothing is added to the product for the Extraction Process

No Solvents

No Steam

No CO2

No Hot Gasses

No water

No High Pressure

No Press

The principle advantages of this system is NO solvent is used (solventless), only one single piece of equipment with low thermal hazard, and separate collection areas.

Solid plant material is loaded into the cylindrical chamber, a collection vial is installed, the start button is pressed, the system automatically cycles as the pressure is changed and energy is applied. As the material transfers the energy, the most volatile (lighter molecular weight) portion leaves the chamber to be collected, and a less volatile portion is collected internally. Time is allowed for the energy cycle to be completed and then the collection vial is removed, the lightest materials collector is withdrawn and the remaining plant material is removed from the chamber. 

The major advantages to be expected from the SPExtR-5G extractor are: 

  • Solventless
  • Simple operation with a single button start
  • Separate collection of light (terpenes) fractions
  • Separate collection of (decarboxylated) cannabinoid fraction
  • Minimized thermal hazard (a necessity for heat sensitive compounds)  
  • No high pressures
  • Nothing is added in the process besides from the starting plant material to and a collection vial.


There are several important design features that make SPExtR an outstanding tool in the laboratory:

  • Simple to clean. – Mostly stainless steel with minimum glass usage 
  • No gear pump to clean or leak.
  • Simple design allows for easy set up and moving location.
  • Requires little space for operation.
  • Information/process developed is easily scaled up to larger sized models.


The SPExtR-5G is designed to separate thermally sensitive compounds in a particular molecular weight range. The system utilizes a pressure change at start then the material in the chamber is subjected to a certain amount of energy. This energy transfer takes advantage of the molecules mean free path. Once parameters are reached, time is allowed for a complete energy cycle and collection occurs. 


  THC Extraction



The SPExtR system is designed as a batch system.  

  • The plant material is loaded into the process chamber and a collection vial is placed.
  • The operator then simply presses the start button on the touch screen.
  • Liquid nitrogen and cooling water flow are automatically controlled  
  • Cycled valves are automatically controlled.
  • The energy input is started and is applied to plant material
  • Cannabinoid fraction is collected and the lighter molecular product is collected separately
  • The collection vial, left over plant material and light end collector are removed 
  • New plant material, a new vial and light collector are then loaded and the process repeated. 

The SPExtR will accept material for process that has been properly dried and is over 0.039” in size. 


With the SPExtR-5G system the processed material will only come in contact with 300 series stainless steel, Viton, Tygon (or equal), neoprene and glass. The system will need the following customer connections, cooling water (~1 gpm), single point electrical connection 208-240 V single phase 4-wire 40 amp, low pressure liquid nitrogen (3/4-16 flare), 60 PSI compressed air.


All of the readouts and controls are conveniently grouped on a touch screen panel.
