🔍 Extraction Methods We Support

Cannabis processors use several key methods to extract THC, CBD, terpenes, and other compounds. We provide gases and solvents for the three most common:

Hydrocarbon Extraction

A highly efficient, low-cost method ideal for producing high-terpene extracts (HTE) and live resin.

Available Hydrocarbons Include:

• N-Propane

• N-Butane

• Iso-Butane

• Custom blends, such as:

  • Iso-Butane 30% / N-Propane 70%

  • Iso-Butane 70% / N-Propane 30%

  • N-Butane 80% / Propane 20%

  • N-Butane 70% / Propane 30%

  • N-Butane 50% / N-Propane 50%

Benefits:

• Low extraction temperature preserves cannabinoids and terpenes

• Quick and efficient process

• Ideal for flavorful concentrates and high terpene content

CO₂ Extraction

A clean, solvent-free method preferred for full-spectrum extracts, edibles, and vape oils.

CO₂ Products Offered:

• CO₂ cylinders (20#, 50#, 100#)

• Liquid CO₂ tanks (160L, 230L)

• Microbulk & bulk CO₂ delivery systems

Benefits:

• Non-toxic and non-flammable

• Adjustable pressure/temp for selective extraction

• No residual solvent concerns

---

Ethanol Extraction

Widely used for large-scale production due to its affordability and ability to extract both cannabinoids and terpenes.

We Offer:

• Pure Ethanol (200 Proof)

• Ethanol/Heptane blends

• Storage and handling guidance

Benefits:

• Effective for high-throughput labs

• Compatible with cold or room-temp processing

• Easily scalable

🧊 Dry Ice for Extraction & Post-Processing

We supply dry ice in multiple forms to support winterization, storage, and solvent recovery:

• Dry Ice Rice

• Nuggets

• Blocks

Applications:

• Cooling solvent during extraction

• Trapping residual gases

• Flash freezing biomass
