Cannabis Extraction Lab Design: The Definitive Guide to Building a Safe, Efficient, Profitable Lab
Learn how to design a cannabis extraction lab the right way: layout, utilities, safety systems, workflow, and bottlenecks that actually matter.
Cannabis Beverage Formulation Science: Nano Emulsion, Stability, and Why Most THC Drinks Fail
Why Most Cannabis Beverages Fail Within 6 Months Cannabis nano emulsion for beverages requires a Z-average droplet size of 20-50nm (under 100nm acceptable) with PDI below 0.20, made by high-pressure homogenization at 15,000-30,000 PSI or ultrasonication at 20-25 kHz, with a nonionic surfactant blend at HLB 13-15. Onset drops from 45-90 minutes for a standard [...]
Closed-Loop Extraction Systems for Cannabis: How They Work, What Matters, and What Fails
What is a closed-loop extraction system, and why does it matter? A closed-loop extraction system recovers and reuses its solvent in a sealed circuit instead of venting it. In cannabis processing it moves butane, propane, or a blend (commonly around 70:30 butane to propane for live resin) through chilled biomass, dissolving cannabinoids and terpenes, then [...]
CBD Isomerization Troubleshooting: 8 Failures and How to Fix Them
What is CBD Isomerization? CBD isomerization is an acid-catalyzed rearrangement that converts cannabidiol into delta-9 THC, delta-8 THC, or other THC isomers. The reaction uses a Lewis or Bronsted acid catalyst (p-toluenesulfonic acid, boron trifluoride etherate, sulfuric acid, or others) to protonate the CBD molecule and trigger ring closure at the cyclohexene ring. The resulting [...]
CBD Isomerization Byproducts: How to Identify and Prevent Them
Every CBD isomerization reaction produces byproducts. That is not a failure. That is thermodynamics. The acid catalyst does not care which ring closure pathway the molecule takes. It offers activation energy, and the CBD molecule responds by forming a distribution of products: delta-9 THC, delta-8 THC, iso-THC isomers, and degradation compounds that show up as [...]
Cannabis Crude Oil Degumming: The Complete Guide to Removing Phospholipids Before Distillation
What is degumming in cannabis processing? Degumming is the step that removes phospholipids and related polar lipids from crude cannabis oil before distillation. If winterized crude still darkens hard in the still, leaves stubborn residue on hot surfaces, or produces a distillate that tastes flatter than it should, degumming is usually the missing step. Most [...]
Nano Emulsion Troubleshooting: 6 Failures That Kill Cannabis Formulations
Your nano emulsion separated overnight. Or it was cloudy when it should have been clear. Or the particle size analyzer came back at 350nm after your sonicator ran for 20 minutes. Every formulator hits these walls. The difference between the ones who fix them and the ones who dump batches comes down to understanding which [...]
How to Make Cannabis Tinctures: Ethanol Extraction, Dosing & Shelf Life
QWET in one paragraph: freeze the decarboxylated cannabis (240F for 40 minutes for THC, 250F for 60 minutes for CBD) and 190-proof ethanol separately for 24 hours at -20F (-29C), combine at 1 gram of flower to 5 mL of ethanol, wash for 3 minutes, and filter cold through a coffee filter or a 25-micron [...]
How to Make Bubble Hash: Ice Water Extraction From Start to Finish
Bubble hash in numbers: wash water at 33 to 40F, never above 45F; ice to water at 1:1 by volume, 1.5:1 in a room over 72F; a 15 to 20 minute cold soak before the first 90-second wash; a 220-micron work bag over a 160 / 120 / 90 / 73 / 45 / 25 [...]
Short Path Distillation Cannabis: Complete Setup and SOP Guide
What Is Short Path Distillation? Short path distillation is vacuum fractional distillation of decarboxylated cannabis crude in a 2 L to 12 L boiling flask with 5 to 15 centimeters between the evaporating surface and the condenser, run at 50 to 150 microns so the cannabinoid main body comes over at a 130 to 160 [...]
