Vacuum purge is a process used in cannabis extraction to remove solvents by applying a vacuum to lower the boiling point of the solvent.
Also called / Category:
Also known as vacuum extraction; Extraction & Processing.
Key takeaways:
- Helps ensure concentrates are pure and safe for consumption.
- Commonly used in the production of BHO (Butane Hash Oil).

What it is / How it shows up:
Vacuum purge is a term often seen in product descriptions or extraction method explanations on cannabis product labels and menus. It refers to the process of using a vacuum chamber to remove solvents from cannabis extracts, which is critical in producing clean, solvent-free concentrates. This method leverages a vacuum to reduce the boiling point of solvents like butane or ethanol, allowing them to evaporate at lower temperatures and leave behind pure, potent extracts. This technique is a standard step in producing various cannabis concentrates, ensuring that any residual solvents are effectively purged and the final product is safe for consumption.
How it’s measured or identified:
- Residual solvent analysis in lab tests.
- Quality certificates from extraction facilities.
- Labelling on product packaging.
Use in context:
- "The vacuum purge process ensures our concentrates are clean and potent."
- "After extraction, we use vacuum purging to remove any residual solvents."
- "Our products undergo rigorous vacuum purging for safety."
Safety & compliance in Canada:
- Compliant with Health Canada regulations for solvent use in cannabis extraction.
- Ensures products meet safety standards for human consumption.
- Mandatory solvent testing for commercially sold cannabis products.
