Depending on how you finish your extraction and how long you recover, you can control how much solvent you recover. Under normal running conditions, the BHOgart loses less than 300 ml each time from the leftover butane in the hoses. The bigger the extractor the more loss is inherent to the design. The main places where solvent is released is in the material/material columns the more of them you have the more solvent you end up loosing in the system. Another spot where hydrocarbons are released is in the product Honeypots, or the extract itself. Through using best practices in solvent recovery the amount of solvent released can be reduced significantly.
Typically a Solvent extractor system will recover 95% of the solvent used during extraction.
on average around 0.5lbs per continues extraction, or 1-2lbs per full batch cycle
