The dual jacketed glass crystallization filter reactors, or isolation filter reactors, are designed to create an ideal environment for a synthetic reaction of cannabis extracts using controlled temperature and vacuum. All Ai reactors feature adjustable stirring speeds and a constant pressure-feeding funnel that allows you to add material to the vessel at a uniform and controlled speed. The built-in condenser makes it possible to recover solvents.

Crystallization of CBD or THCa is a precipitation process in which CBD solids form in a solvent, usually pentane or heptane. To crystallize CBD, the distilled CBD oil must be dissolved in a solvent forming a supersaturated solution. This solute is then chilled, making the CBD or THCa precipitate out of the solution and crystalize.


  • Now includes a FREE high-quality thermal insulation jacket (a $459 value) with open/close viewing window and top/bottom adjustable drawstrings, specially designed and made for Ai glass jacketed reactors. These jackets will extend chiller life, allow you to go down to a lower temperature, and also cut your utility bill.
  • The dual jacketed model allows you to draw a vacuum from the outer jacket, thus protecting your recirculating fluid temperature and giving you the best control over your work. It also helps prevents frost from forming on the outside of the vessel, allowing you to see clearly into your material.
  • Solvent-resistant PTFE on all sealing components ensures long time durability and operation.
  • All glassware is hand-made from food-grade high borosilicate glass that is heat/cold/corrosion-resistant.
  • The adjustable stirring rate provides great torque or high speed.
  • Patented PTFE stirring rod bearing for reliable and quiet operation.
  • Optional multi-layer stirring blades for optimal reaction results.
  • Wide range of temperature operations, from -110F to 400F.
  • Large condenser cooling surface for exceptional condensation performance.
  • Rugged stainless steel reinforced PTFE stirrer with anchored agitator, suitable for a wide range of viscous materials.
