Versatility is also part of the package. In addition to the internal short path condenser for cannabinoid collection, an external condenser is included for terpenes collection – a unique Pope advantage! A cold trap is also included to protect the vacuum pump. The body and internal condenser come apart for easier cleaning. The external condenser can also be utilized to provide the user with a continuous solvent evaporation system, substituting for a rotary evaporator. Stainless steel conversion kits, feed pumps and other items are also offered.
Depending on several factors including initial plant quality, harvesting, extraction and other processing operations and techniques, plus product goals, distillation rates, yield and purity can vary. It is typical to make 2 passes through the system, the first for gas and volatiles removal, the second for cannabinoid distillation. However, some users perform a single pass and others may make 3 or more passes, depending on material and goals, (for example collecting various terpenes fractions). Feed rates with the 2″ Pope still normally range from 250 to 500 ml/hr or more and overall throughput from 0.6 to 1.5 liters or more per an 8-10 hour day of feed material. Final cannabinoid purity often ranges from 85 – 95%, with some reporting more than 96%.
Other sizes in the glass Pope Cannastill line include the 4″ and 6″ diameter systems, each similarly equipped, but with larger components and greater power and throughput. The 4″ still typically runs at 0.8 to 1.8 liters/hr and from 2 to 5 liters/day, the 6″ still at 1.6 to 3.6 liters/hr and 5 to 10 liters/day.
