Pure Botanical Extraction — No Strain Left Behind
Why the Standard Exists
Most Extraction Destroys What Makes Hemp Valuable
When you extract cannabinoids and terpenes from hemp using conventional methods — CO2, ethanol, or hydrocarbon — you are applying heat, pressure, or harsh solvents to a plant that spent months developing a precise, complex chemical profile. That profile is what makes each strain unique. And most extraction methods destroy it.
CO2 requires pressures of nearly 8,800 PSI and two separate extraction runs. Ethanol boils at 176 degrees F — the same temperature range at which terpenes begin to degrade. Hydrocarbon solvents like butane and propane create scaling challenges and require aggressive de-waxing steps.
The result is an extract that no longer faithfully represents the plant it came from. The strain-specific terpene profile is gone. The natural cannabinoid balance is altered. What remains is generic.
Mark Vuozzo spent years asking one question: how do you extract hemp in a way that preserves everything that makes it valuable?
The Answer
Low Pressure. Low Temperature. Strain-Specific.
The PBX Standard is Mark Vuozzo’s proprietary quality control program built on the Comerg patented Aerosol extraction platform. It uses liquified gas aerosol technology to extract hemp at low pressure and low temperature — conditions that mimic the plant’s natural environment rather than fighting against it.
The extraction process selectively draws out terpenes and heavier resins — the cannabinoids — without disturbing water-phase plant components or exposing the extract to destructive heat. The result is a full spectrum resin with an unaltered terpene profile and minimal wax content, requiring no aggressive post-processing.
This is not just a choice of extraction platform. It is a documented, controlled, repeatable quality control system — with work instructions, SOPs, and measurement standards applied to every batch. That discipline is the PBX Standard.
Compare the Methods
| Method | Conditions | What It Costs the Plant |
|---|---|---|
| CO2 | Supercritical pressure near 8,800 PSI, two separate runs | Terpenes and cannabinoids extracted separately; profile reassembled, not preserved |
| Ethanol | Boils at 176°F | Terpene degradation begins in this temperature range |
| Hydrocarbon (butane/propane) | Flammable solvents, aggressive de-waxing | Safety and scaling limits; heavy post-processing |
| PBX Standard (R134a aerosol) | Low pressure, low temperature, closed loop | Nothing — the strain’s full profile stays intact |
The Inventor
Mark Vuozzo — Chief Technical Officer, PurBlend Science, Inc.
Electronics Engineering background. Semiconductor industry. Automated Test Equipment. The precision mindset of someone who spent a career measuring what mattered and controlling for what could go wrong. When Mark came to hemp, he brought that discipline with him.
His mission: bridge the gap between farmers and the oil produced — delivering full spectrum, strain-specific oils that are truly representative of the farmer’s craft.
What PBX Means in Practice
Precise
Every extraction parameter — pressure, temperature, time, solvent ratio — is controlled and documented to exact specification. There is no guessing. There is no batch-to-batch variation. Precision is the first pillar because without it, nothing else matters.
Automated
The Comerg platform is automated by design. Automation eliminates human variability from the extraction process. The same parameters produce the same result every time. Consistency is not a goal — it is built into the process.
Safe
The aerosol extraction technology uses a compound that is FDA-approved, GRAS-classified (Generally Recognized as Safe), and approved under EU Directive 2009/32. There are no flammable solvents. No residual contamination. No safety compromises.
Strain-Specific
This is the purpose of everything above. The precision, automation, and safe chemistry exist to serve one goal: capturing the exact terpene and cannabinoid profile of the original hemp strain. Not a generic extract. The strain itself, in oil form.
PBX-Standard oils contain a minimum of 7 naturally occurring terpenes, typically at total levels above 2.5%, with potentially up to 16 or more hemp-based terpenes present.
