Solventless vs. Solvent-Based Extraction: MIDSFACTORY’s Approach to Purity and Potency
No doubt, cannabis extraction methods fundamentally shape product quality, safety, and consumer experience. Solvent-based techniques use chemicals like butane or CO₂ to isolate cannabinoids and terpenes, while solventless methods rely on physical processes such as heat, pressure, or ice water.
MIDSFACTORY, a San Francisco-based extraction company, prioritizes both purity and potency (concentration of active compounds) in its concentrates. This article explores the key differences between these extraction approaches and how MIDSFACTORY balances them to deliver consistent, high-quality products.
What are the Extraction Methods?
Solvent-Based Extraction
Solvent-based extraction involves soaking cannabis in a solvent, which dissolves cannabinoids and terpenes. The solvent is then evaporated, leaving behind a concentrated extract. Common solvents include butane, propane, ethanol, and CO₂. The process is:
Step 1: Soaking cannabis in solvents (e.g., butane, ethanol).
Step 2: Separating the solution from the plant material.
Step 3: Evaporating the solvent to leave a concentrated extract.
The process brings in high efficiency, scalability for large production, and versatility in creating products like shatter or distillate oils.
Solventless Extraction
Solventless extraction uses physical means—such as pressing, agitation, or ice water—to separate trichomes from the plant. Popular methods include rosin pressing and ice water (bubble hash) extraction.
Ice Water Hash: Agitates cannabis in ice water to separate trichomes, yielding bubble hash.
Rosin Press: Applies heat and pressure to flower or kief, producing terpene-rich rosin.
The process preserves full-spectrum cannabinoids and terpenes, no solvent contamination, and eco-friendly processes.
