Not 100% sure there mate, I never did strip runs with my boka and don't do them with my bubbler either :teasing-neener:
As for loss from the cuts jars, I wouldn't panic it will mainly be the higher alcahols that you don't want in your drink anyway :handgestures-thumbupleft: I would avoid leaving them for long periods in hot weather though :handgestures-thumbupleft:
Enigma wrote:Hi bundaboy, not sure if you seen all the pics but the notes l took was my first run (turbo @ 14% approx ) As my notes said, as soon the temp risen abit it started to smell horrible and then when very high fast, shut down at 79c because l couldn’t handle the smell ( maybe because it’s turbo, yet to learn) So not really a stripping run, just seeing how my Still performs, ABV was high but even middle cuts didn’t smell quite right. Maybe because of Turbo or maybe collecting to fast even though ABV is high, as l said before, still learning. Then l redistilled what l collected abit slower, much better, but lost abit doing that but happy to have something better to drink. Also the other reason l redistlled, l need more practice. My drink of choice is Bundy and Scotch ( not together :laughing-rolling: )
Cheers

I've just re read the above posts and didn't realise you didn't really get an answer about how a bubbler works and why it doesn't need strip runs so sorry about that. I tracked this thread down and it should help explain better than I could 8-} :laughing-rolling:

By the way I make both brown spirits and neutral with my bubbler and only neutral with my boka when I had it :handgestures-thumbupleft:

A boka will pull azeo (96%) straight from a wash it will just be very slow, like 500ml per hour slow. I was using ceramic bits, copper pipe off cuts and stainless scrubbers as packing. The thing I found with the boka is it needed alot of reflux, when I first started I was trying to run to a temp and kept turning the power up and down causing chaos in the colomn. I worked out that I would turn the power up to the point where the condencer could only just but comfortably keep up (you don't want vapor coming out the top), this will give you maximum reflux then adjust take off till % is where you want it. Forget temps, only use thermometer to tell you when run is near over. Temp should hold steady till tails. It may not be that magic 78deg people talk about but don't worry. The temp is governed but the alcahol content more than the power.
Hope that makes sence, if not I'll have another go for ya :handgestures-thumbupleft:
