PURE5 R134a cannabis extraction creates superior extract

COMERG’s PURE5 R134a cannabis extraction creates superior extract
An image of an extract achieved with PURE5TM equipment operated in safer, room temperature PBXTM process with food grade solvent.

PURE5 has shared independent, third-party lab results of its extracts and is ready to compare to those created by other cannabis extraction technologies.

Results from an independent analysis has shown that the PURE5TM R134a extraction technology creates a far more superior extract that can be produced quickly, while achieving higher yield at a lower operations cost compared to other cannabis extraction techniques currently in use, in particular, utilising CO2 and Ethanol as solvents.

Since the PBXTM process delivers pure cannabis oil without waxes and solids, the extract is ready to be used in food grade products without any post processing. While in other technologies multiple stages of post processing is required.

Lab report highlights

Below are some highlights of the lab reports of different cannabis strains using PURE5 machines utilising the PBX process.

Extraction of cannabis flower: White Fire, yield 26.28%, corresponding to plant’s 25.91% target components:

Type Starting Plant Extract Exhaust Plant
THC 24.10% 80.10% 2.33%
THCA 1.47% 0.62% 0.23%
CBD 0.00% 1.34% 0.00%
CBDA 0.28% 0.00% 0.00%
Total C% 25.85% 82.06% 2.56%
a-Pinene 0.00% 0.05% 0.00%
b-Myrcene 0.01% 0.09% 0.00%
b-Pinene 0.00% 0.03% 0.00%
Limonene 0.02% 1.82% 0.01%
Terpinolene 0.00% 0.11% 0.00%
Linalool 0.01% 0.01% 0.00%
b-Caryophyllene 0.02% 0.07% 0.00%
Total T% 0.06% 2.18% 0.02%
Total 25.91% 84.24% 2.58%

Extraction of cannabis trim: Pineapple Chunk, yield 14.26%, corresponding to plant’s 13.62% target components:

Type Starting Plant Extract Exhaust Plant
THC 11.50% 63.80% 1.19%
THCA 1.67% 7.00% 0.42%
CBD 0.01% 0.01% 0.01%
CBDA 0.42% 1.84% 0.18%
Total C% 13.60% 72.65% 1.80%
a-Pinene 0.00% 0.11% 0.00%
b-Myrcene 0.00% 0.19% 0.00%
b-Pinene 0.00% 0.01% 0.00%
Limonene 0.00% 4.63% 0.00%
Terpinolene 0.00% 0.41% 0.00%
Linalool 0.00% 0.02% 0.00%
b-Caryophyllene 0.01% 0.11% 0.01%
Total T% 0.02% 5.48% 0.02%
Total 13.62% 78.13% 1.82%

You may notice that if 15% is the total T+C potency in the plant, the yield will be matching the potency, with that said PURE5 equipment can strip down completely the target components and further separate them if desired.

Dr George Stantchev, the technology’s inventor and CEO of PURE5, said: “The independent lab results prove that our extracts are far superior and can be produced quicker, while achieving a higher yield at a lower cost compared to our competitors.

“The response we’ve received from the cannabis industry has been overwhelmingly positive even before these results became public, and now that they’re out we expect the PBX (Pure Botanical Extraction) process to quickly become the new industry standard.”

The extraction devices, sold under the trademark PURE5, use the patented PBX process.

For a background, originating from essential oil and flavour industry, PURE5 technology gets its name for delivering superior extracts challenging all five senses:

  • Sight: The light colour and clear appearance of the extract is more visually apparent and pleasing to the naked eye;
  • Touch: Smooth and oily texture with no by-products in the final extract;
  • Taste: A concentrated, unadulterated flavor unique to the natural botanics;
  • Smell:  An aroma bouquet that completely preserves the natural plant scent; and
  • Sound: The process is safer, quieter and more efficient.

PURE5 developed its Liquefied Gas Extraction Technology in 2004 for food, pharmacy, and perfumery products, back in 2015 found that overwhelming interest has been coming from the cannabis industry, due to its pure and potent extracts.

Since 2015 under the trademark PURE5 there have been multiple equipment sizes available starting from 20L to 1000L vessels corresponding to extractions up to 8000lb/day. The machine is a game-changer because it uses room temperature to process the material, takes a fraction of the energy as its CO2 competitors, can handle fragile natural ingredients no degradation and the process does not produce bi-products.

  1. YAY! Lets make extracts that humans consume with 1,1,1,2-Tetrafluoroethane (100 year Global Warming Potential of 1300-1550), and at the same time vent some into the atmosphere. Ya’ll are ahead of your time!
