Short Path Distillation (SPD) is a technique that uses thermal and pressure manipulations to yield a high potency distillate product. Using a method of thermal evaporation across a short distance, it is possible to produce clean, potent extracts, without significant degradation of desirable compounds. The SPD process is for refining products with precise boiling points, such as cannabis extracts. Distillates are widely sought after as a clean and consistent medicine for MMJ patients in Michigan.
