The Benefits of a Four-Stage Wiped-Film Still for Processing Cannabis

The concept of two passes for the distillation of cannabinoids is understood by many; one pass for devolatilizing or ridding the feed material of gasses, ethanol, water, light terpene ends, etc., so that the next, cannabinoid distillation pass can be performed with greater vacuum, throughput, purity, yield, and product clarity. So why four passes? To accommodate the widest ranges in starting materials, extraction methods and other pre-distillation steps, and optimization of throughput and choices of finished products.
