Comparision principal of short path and wiped film distillation
Short Path

Pros of Short Path Distillation
Short path distillation produces a high-quality product. You can get multiple fractions during the distillation process, depending on how high you raise the temperature. The multi-position flask collects the different fractions into different flasks, which allows for easy distillation. Like most distillation processes, short path requires an experienced operator to efficiently get a high-quality product. It is limited in scale and production, so it's not ideal for large-scale operations |

Wiped Film
| Pros of Wiped Film Distillation Wiped film has an extremely efficient and even heat transfer due to its thin film of oil, no matter how viscous the fluid is. This results in a high-quality product. The process can easily be used for large-scale productions, so it's ideal for large batches of distillation. If you run in a continuous mode, it also reduces the exposure time of the oil and increases productivity. Cons of Wiped Film Distillation Two passes are required through the system to achieve a high-quality distillate. After the first pass, there are still some leftover terpenes and volatiles. The second distillation requires a little more time, but results in a higher-quality end product. |
