To create the best cannabis concentrates, you need high-quality raw material and first-class extraction technology. Unfortunately, the most common cannabis extraction methods include toxic solvents or take a long time to produce low yields.
For cannabis manufacturers who want a cleaner, higher-fidelity oil for their products, there’s a superior cannabis extraction option: Low Pressure Isolation. Low Pressure Isolation (LPI) allows for greater throughput, higher THC/CBD extraction, and multi-stage refinement. The process produces a cleaner, cannabinoid-centric oil.
What Is Low Pressure Isolation?
Low Pressure Isolation, also known as Hydrofluorocarbon Extraction, is a low-temperature, low-pressure, non-hazardous way of extracting cannabis compounds from raw plant material. LPI uses a mix of proprietary gases and room-temperature solvents to separate cannabinoids from unwanted items, like pesticides.
According to Casey Reischl, Caliva’s Extraction Manager, “LPI is non-toxic and non-flammable, so it is a great, great method of extracting plant material. It is definitely super unique to to the industry. There aren’t too many people using that method.”
Why Is LPI Better Than Traditional Cannabis Extraction Methods?
Low Pressure Isolation has several benefits over other cannabis extraction methods, including overall manufacturing safety and oil purity.
Low Pressure Isolation’s Advantages Over BHO Extraction
“BHO can be dangerous. There’s higher risk of explosions, and then the infrastructure and building requirements to get something like that permitted is also extremely expensive,” says Reischl. “[An LPI] unit can be in essentially an open warehouse space with basic safety features.”
Low Pressure Isolation’s Advantages Over CO2 Extraction
Less-toxic extraction methods, like Supercritical CO2, can’t compete with the processing capability and speed of LPI. Low Pressure Isolation can yield hundreds of kilos of cannabis oil every month. “We are able to process so much more material than any CO2 machine out there. They just don’t have the throughput that our machine does,” explains Reischl.
Low Pressure Isolation’s Advantages Over Alcohol-Based Solvents
LPI also produces a cleaner, purer oil than alcohol-based solvents, so you’re no longer choosing between processing speed/yield and purity. “Alcohol-based solvents, like ethanol, can process quite a bit of material as well. But a lot of ethanol-based extracts require quite a bit of cleanup.”
High-quality cannabis concentrates require a pure and potent oil base.
Why Should You Choose Cannabis Oil Made Via LPI?
Simply put, cannabis oil made using Low Pressure Isolation is as true to the original product as possible. LPI produces bigger oil yields with higher-quality results than other extraction methods.
“A lot of CO2 and systems that introduce a lot of heat and a lot of pressure can essentially degrade the product, so you get a crude oil [that] doesn’t have that full spectrum of cannabinoids,” explains Reischl. With LPI, “We’re able to do it in a less aggressive manner that allows us to get a full-spectrum extract in the end.”
