I. Introduction
Overview of Cannabis Extraction
In the cannabis industry, extraction is a critical process that transforms raw plant material into valuable concentrates, oils, and other derivatives. As the market for high-quality extracts continues to grow, so does the demand for more efficient and effective refinement methods that can capture the entire essence of the plant.
Introducing PURE5™ Extraction
PURE5™ stands at the forefront of this evolution, offering a groundbreaking approach to cannabis extraction. Utilizing R134a aerosol gas, PURE5™ has developed a method that not only simplifies the extraction process but also elevates the quality of the final product, ensuring the preservation of the plant’s natural compounds.
II. The PURE5™ Extraction Process: From Plant to Final Product
The PURE5™ extraction process (also known as PBX-Standard R134a method) is a sophisticated, fully automated method that harnesses the unique properties of R134a aerosol gas to extract the full spectrum of valuable compounds from botanical sources. This innovative approach is designed to maximize the efficiency and purity of the oil extraction while preserving the delicate balance of terpenes, cannabinoids, and other essential components found in the plant material. Here’s a detailed breakdown of the process:
-
- Preparation of Plant Material
The extraction process begins with the careful selection and preparation of the plant material. The botanical source is typically dried and ground into a fine consistency, optimizing the surface area for the extraction. The plant material is then loaded into the extraction vessel, ensuring an even distribution to facilitate uniform exposure to the solvent. - Introduction of R134a Aerosol Gas
Once the plant material is in place, the system introduces R134a aerosol gas into the extraction chamber. R134a, known for its excellent solvency properties and low boiling point, penetrates the plant material efficiently. Unlike traditional solvents, R134a operates at low temperatures and pressures, which helps preserve the integrity of sensitive compounds such as terpenes and cannabinoids and prevent degradation. - Solubilization and Extraction
As the R134a gas passes through the plant material, it selectively solubilizes the target compounds. Terpenes, cannabinoids, flavonoids, and other valuable phytochemicals dissolve into the R134a solvent, forming a rich solution. The gentle nature of the process ensures that the full spectrum of compounds is captured, maintaining the plant’s original profile and potency. - Separation of Extract from Plant Material
After the desired compounds have been solubilized, the system separates the extract-laden R134a solution from the plant material. This step is crucial to ensure that no plant particulates or unwanted residues remain in the final product. The plant material, now devoid of its valuable constituents, is removed, and the extract solution is collected for further processing. - Evaporation of R134a Solvent
The next step involves the careful evaporation of the R134a solvent from the extract solution. Due to R134a’s low boiling point, this process can be achieved rapidly and efficiently without the need for high temperatures. As the solvent evaporates, it leaves behind a concentrated, pure extract that contains all the solubilized compounds. The solvent is then condensed and recycled back into the system for repeated use, making the process highly sustainable and cost-effective. - Purification and Refinement
The raw extract obtained after the aerol extraction does not require any post processing like the other extraction methods in the industry. The solubility of the aerosol is strict to the terpenes, cannabinoids and the phenolic compounds in high concentration like 10/5/85 percent in total and does not draw any impurities like wax, lipids and chlorophyll. That saves time and preserves the natural compounds without need of additional purification with ethanol, heat or cold manipulation. In some of the units there is an auxiliary CRC column that can help refining undesired impurities as mold, pesticides or color. - Final Product Collection and Packaging
The extract is collected-from the machine and ready for formulation into various end products such as oils, tinctures, edibles, or topicals. The final product is packaged under stringent quality control measures to ensure consistency, potency, and safety. The PURE5™ PBX-Standard extraction process, with its precision and efficiency, results in a product that retains the full spectrum of the plant’s therapeutic compounds, offering enhanced efficacy and a richer sensory experience for the end-user.
- Preparation of Plant Material
Comparison to Traditional Methods
While the PURE5™ PBX-Standard R134a extraction process is cutting-edge and highly efficient, it’s essential to understand how it stands in contrast to more traditional extraction methods. Each of these traditional methods—CO2 extraction, hydrocarbon extraction, ethanol extraction, steam distillation, and water-alcohol extraction—has its own merits and drawbacks, often influenced by factors such as cost, safety, efficiency, and the quality of the final product.
-
- CO2 Extraction
-
- Process Overview: In CO2 extraction, carbon dioxide is used as the solvent. Under high pressure and low temperature, CO2 is converted into a supercritical fluid that extracts compounds from the plant material.
-
- Comparison: The solubility of CO2 extraction is very wide that ois why it is renowned for producing crude extracts that needs heavily refinement and it requires expensive equipment that can be energy-intensive. The process also involves high pressures, which degrades sensitive terpenes and other compounds. That us why CO2 can only extract the sesqi terpenes while the mono terpenes are degraded and lost.
-
- Hydrocarbon Extraction (e.g., Butane, Propane)
-
- Process Overview: Hydrocarbon solvents like butane or propane dissolve the plant’s active compounds at relatively low temperatures to limit extraction of chloropyl wax and lipids.
-
- Comparison: Hydrocarbon extraction is efficient but carries significant safety risks due to the flammability of the solvents and obtaining a licence for it is very often tough and expensive. Additionally, hydrocarbons may leave behind harmful residues if not properly purged.
-
- Ethanol Extraction
-
- Process Overview: Ethanol dissolves mosly the polar compounds in the plant material, capturing a wide range of the cannabinoids and very limited terpenes. Usually only fraction of the sesqi terpenes get extracted.
-
- Comparison: While ethanol is an effective solvent, it also extracts sugars, chlorophyll and other undesirable components, requiring cryo temperature extraction and additional refinement.
-
- Steam Distillation
-
- Process Overview: Steam distillation involves passing steam through plant material to volatilize and condense essential oils.
-
- Comparison: This method is particularly suited for essential oils but is less effective for extracting cannabinoids due to the high evaporation temperatures of the cannabinoids compared to the terpenes.
-
- Hash Rozin Extraction
-
- Process Overview: This method uses low temperature freezers to freeze the tricomes of the cannabis plant then break them while agitating in cold water. Then the tricomes are collected and pressed under heat to dercaboxylate and convert to an oil.
-
- Comparison: While Hash rosin extraction is simple, it requires intensive labor and is is less selective. The yields are 30-40% compared to the 97% of the aerosol extraction.
-
- CO2 Extraction
PURE5™ PBX-Standard R134a refinement process stands as fully automated, fast, high quality, efficient, and eco-friendly extraction. It offers significant advantages regarding safety, solvent recovery, and product quality, particularly when compared to traditional methods that may involve higher costs, more significant risks, lower concentrate quality, and more intensive post-extraction processing.

The PURE5™ extraction process is gentle and precise, utilizing R134a, a low-pressure, non-toxic gas operating at near-room temperatures. This approach is ideal for preserving the delicate balance of terpenes and cannabinoids, often degraded or lost entirely in more aggressive extraction methods.
By maintaining lower temperatures and avoiding harsh solvents, the PURE5™ system ensures that the complete terpene profile is preserved. This includes not just the significant terpenes but also the minor ones, which can significantly influence the entourage effect and the overall efficacy of the extract. Additionally, the system’s efficiency in preserving cannabinoid content means that the final product retains high levels of these active compounds, ensuring maximum bioavailability and therapeutic potential.
Comparison with Competitors
When comparing the PURE5™ PBX-Standard R134a method to other extraction techniques, the differences in compound preservation become even more apparent. Traditional approaches often involve trade-offs, whether in terms of cost, safety, or the quality of the final extract.
-
- CO2 Extraction (Subcritical and Supercritical): CO2 extraction, whether subcritical or supercritical, is one of the most commonly used methods in the industry. However, it comes with significant drawbacks. The high pressures and temperatures required can lead to the degradation of volatile compounds, including many terpenes. Additionally, CO2 extraction systems are expensive, often requiring multiple machines and additional permits for operation. This complexity increases costs and the likelihood of losing valuable compounds during the process, leading to a less robust final product.
-
- Hydrocarbon/Hexane Extraction: Hydrocarbon extraction methods, such as those using butane or hexane, effectively in stripping cannabinoids and terpenes from the plant material. However, these methods raise significant safety concerns due to the flammability and toxicity of the solvents involved. Moreover, the extracts often require further purification to remove solvent residues, which can degrade the quality of the terpenes and cannabinoids. The environmental impact of these solvents is another critical issue, making hydrocarbon extraction a less sustainable option.
-
- ETOH Extraction (Ethanol): Ethanol extraction is a popular choice for its efficiency and ability to process large volumes of plant material. However, ethanol is not selective and can dissolve both desirable and undesirable compounds, including chlorophyll, which can affect the taste and color of the final product. Additionally, ethanol extraction often requires extensive post-processing, such as winterization, to remove impurities. This additional processing can reduce the terpene content, leading to a final product that lacks the full spectrum of natural compounds.
-
- Water-Alcohol Solutions & Pure Steam Extraction: Water-alcohol extraction methods and pure steam distillation are generally less efficient at preserving the full spectrum of cannabinoids and terpenes. These methods often result in lower yields and incomplete preservation of the plant’s natural profile. Steam distillation, in particular, operates at high temperatures, which can cause significant terpene loss. While these methods may be suitable for certain applications, they do not offer the same level of preservation and efficiency as the PURE5™ system.
In summary, the PURE5™ extraction process stands out for its ability to maintain the complete natural profile of the cannabis plant. By preserving the delicate balance of terpenes and cannabinoids, it produces extracts closer to the natural plant, offering superior quality and efficacy.
