I hit 75% on average of mains

Thanks @Demontrich
On average, where does that leave you on potency? Assuming you reduced the crude to 75%.
P.S. what do you have the most trouble with remediating?
Well I usually do go off of final yield, however I was going off finished crude yield so that the OP could see just how much he’ll actually have to load in the flask.
We are yielding about 60-65% mains on our crude.

The runs I’ve done, 86%, 91%, and 92%
75% is what I pull from the decarbd crude.
Imo, potency depends on how you swap flasks. Swap too early you adding Terps, too late tour adding tails. I’m still refining my flask swap times.

mono cow?
@Curious_Roberto posted a link.
the “kit” is pictured in post four of: 500ml or 2L - #4 by cyclopath
what’s included (essentially as pictured…):
mantle, boiling flask, cow, several receiving flasks (I think there might be 4).
pretty sure I can come up with an analog thermometer that fits.
I don’t know what @beaker was using for a cold trap, so you’ll need one of those.
what’s not included: pump, vac gauge (I’ve seen it done without, I don’t recommend starting out that way). I did run into a JB DV-22N digital gauge that measures down to 10um for $150 just the other day. not ideal, but might be sufficient. I’m currently running a JB DV-41 ($250) on our 2L systems. It’s better than running blind…
Also missing klet clips and GL14 connectors. Some folks just run them as if they were hose barbs (push the hose over the threads rather than using the correct adaptor).
I don’t believe that the mantle has built in stirring (I’ll check). even if it does, @beakers stirbars did not make it into my hands, so you’re on your own there as well. [can anyone address how no stirbar will work?!?]
I’m doing a training run for our new crew members this morning, and if I don’t run into any snags, it might be amusing to fire up the little rig and see how it behaves.
If I was to guess, I’d say @beaker was running this on a robinaire hvac pump at one point. He eventually threw several $k at an edwards EM30 & an appropriate vac controller. although I don’t know that he ever hooked this little SPD up to it.
If i do have time to run it, I’ll probably try it with the hvac pump. or at least try pulling the system down with said robinaire.
I’d say it was a decent deal for $250. with the understanding that @Roguelab offered that mostly on sentimental value.

How do you know when to switch to mains?
Do you use ultraviolet light or some other method?
Best way to learn working with uv light assist is running normal runs with the uv on close to the glass wear and dimmed light
Thc turns. Mostard green in first pass and a broccoli stem green on second pass
It takes some practice but the advantage is that once under the belt
You can start with hot. Condensor of the start and use this as one of tour parameters

Still eyeballing it. Getting better however.

I’ll happily take this learners kit if others decline.

Is the BF 1 neck or 2 neck?
One or three. I’m gonna run it with one tonight, because there is no temp probe in the mantle. Happy to ship the 3-neck as well. The two stage robinair looks like it pulls down to 80microns, not ideal, but it will probably work well enough.

I recalled about 10min in that @Beaker had a PiD controller he plugged his mantles into. That was not amongst the bits I managed to retrieve. 140microns was marginal at best.
A variac will do to yet rhe magnet mixer only starts at 1/2 voltage
All yours friend if you are still interested.

Does anyone have experience with usalab.com’s Glass? I’m just trying to gauge where it falls on the scale. Is it cheap Chinese glass, with a markup? Or is it quality? Note, I’d guess there are some quality products that come out of China. Just sayin…
Thanks!
Even Chinese beakers suck, in my opinion. The damn markings were off and threw off the ratios on my entire project. You get what you pay for. This is what I’ve realized with buying equipment so far
Budget Gear (gets the job done…barely): $
Quality Budget Gear (gets the job done right): $$$
Top of the line Gear (gets the job done just a bit better): $$$$$$$$$$$
I rock their re-510 rotovap, and their 2l spd glass kit, and upgraded black case mantle. Zero issues so far. I’ve put thru easily 200+ gallons thru the rotovap, and 3 runs on the spd. 86.7%, 91.6%, and 91.4% thc on all 3 spd runs (1st pass).
Call and ask for David. He’s the owner.
I also run their dlsb-5/10 chiller for the rotovap. I only have 12hrs on it. So far, almost 2x faster than my prior tap runs. All tap runoff goes into plant res.

I have a few of their glass pieces and have bought quite a bit of stainless bits from there as well. Tanks of butane. Dry ice. Vac oil. Filter paper.
Every time I walk into that place im like a kid in a candy store. Especially when they bring you back into the warehouse. Epic.
The big difference between there and china is. You spend a couple more bucks, but if something screwed up you can get it replaced immediately, instead of waiting 2 months for something to ship back and get reshipped from china. Plus if your local, you can get a free soda while your shopping.
10/10 would and will buy from again.
