This hands-on course shows the student how to crystallize CBD from short-path distillate (from the morning class). This course is the final step in removing the THC from the CBD medicine. The course provides instruction in first and second pass re-crystallization steps from hexane. Speed and recovery are emphasized, and the entire process can be performed in under 4 hours with excellent yield.
The course covers safety and step by step procedures; including loading the solvent, cooling, seeding, nucleation and crystal growth. For production reasons crystallization processes tend to focus on encouraging nucleation, producing as many high purity crystals as possible, versus larger crystal growth. Filtering, rinsing and drying crystals rounds out the half-day course.
Come join us for the full day, from short-path distillation to re-crystallization. Take home some seed crystals!
