I’m assuming you’re referring to the short path type of Thin film evaporator. If so, there are a few SOP’s discussed throughout the forum. Most here call them “Wiped Film short path”*(try this term in search bar)
If you are looking for non-short path wiped film SOP, which is often called just “wiped film evaporator or Thin-film evaporator” and has no internal condenser, having only an external condenser (not for the deep vacuum operation under 10mtorr) then there is not an “official” GLG SOP in pdf form, and there is definitely less discussion about their operation on the forum compared to WFE-SPD.
If you are a GLG member, Im pretty sure that @Kingofthekush420 shared his SOP there, and has shared the VTA SOP for the 2-pass operation (light-cut/deep-cut) in one of the threads on F42K. If memory serves me correctly, he also is a proponent of a thorough, hot decarb/de-terp to minimize load of “lights” (less than 20 carbons) on the first pass. (He will chime in here soon and clarify any points about his operational preferences and lab tests i may have missed or not stated correctly.)
There are a few different “camps” of WFE-SPD operators here who like to run these systems a bit differently, each may fight to the death that their method is the technically correct, or “best” way to operate.
In my experience the different operational philosophies expressed here on F42K all have value and their place. Which method is best for you depends on your business case, desired finished product, and upstream feedstock processing implementations/workflow.
