8. Throughout this process, monitor the condenser sightglass and discharge recovered solvent.
Step 2: Decarboxylation
1. Increase heater temperature to 140C (284F) The thermocouple reading of your material should be
123C (253F) As the heater reaches 140C (284F), check the temperature of your material. Make sure you
maintain between 123C (253F) and 130C (266F).
WARNING: Do not put the set point of the heater over 140C (284F) in order to speed up the heating
process. You can damage your material by raising it too high.
2. Continue to monitor the mixer and the material with vacuum. You should have a nice, even vortex and
your material should appear thicker than when started. You may need to increase your mixer speed to
compensate for the thicker material.
3. Monitor the condenser sight glass and discharge as needed.
4. Pull a mild vacuum and increase as you feel necessary. Be careful not to pull too much as “bumping”
may occur (material can pass over into the condenser)
5. Monitor the solution for excessive bumping. A mild boil is the desired outcome
6. Decarb times may vary, a good starting point is 30 minutes as soon as the solution hits 123 C, test
your results as this may not be enough or too much time at temp
7. After timer is done, close vacuum valve and release the vacuum in the system.
8. Using N2 or dried compressed air, charge the system to 5 psi.
9. Drain solution into desired vessel, we recommend filtering it before moving to your next step
10. It is important to drain the solution immediately after decarboxylation is complete to avoid
isomerizing your material
11. Clean system by boiling ethanol or isopropyl, followed by water.
