PURE5™ Extraction

Introduction

In the rapidly changing field of cannabis extraction, safety, efficiency, and product quality are essential. While traditional hydrocarbon extraction methods are effective, they carry significant safety risks due to the flammable nature of solvents like butane and propane. A new solution is non-flammable hydrocarbon extraction, which reduces these risks while maintaining product quality. PURE5™ Extraction is leading this innovative approach by utilizing R134a (tetrafluoroethane) to set new industry standards.

Understanding Hydrocarbon Plant Extraction

Traditional Methods and Their Challenges

Conventional hydrocarbon extraction methods use solvents like butane or propane to separate cannabinoids and terpenes from the cannabis plant. While these methods are effective, they operate under high pressure and involve flammable substances, necessitating strict safety measures and specialized equipment. Associated risks include the potential for explosions, environmental harm, and residual solvent contamination in the final product. Additionally, these methods may not extract the full range of beneficial compounds—such as terpenes, cannabinoids, flavonoids, sterols, and other nutrients—resulting in a lower overall quality and therapeutic potential of the extract.

The Need for Non-Flammable Alternatives

Embracing Safety and Sustainability

The cannabis industry is increasingly adopting non-flammable solvents to improve safety and promote environmental sustainability especially when the process needs to be performed in large volumes and shorter times. Non-flammable hydrocarbon extraction offers several advantages:

Laboratory analyses confirm the efficiency of the R134a extraction process is better than 87%. In one PBX™ case study, hemp flower yielded 26.28% extract with expected 25.91% target actives level. The final distillate contained 80.10% THC, demonstrating high potency, and preserved significant terpene levels (limonene at 1.82% and β-myrcene at 0.09%). Source: PURE5™ Laboratory Results.
