could you guys advise how to use SPD king’s 2l (summit research) setup with E28 pump, poly cooler and straight arms. Haven’t used my unit for 1 year and got all together today and had issues with Apiezon 500 lube that should hold 250 C and it started to melt at 200 and contaminated my flask due to poor quality joints used by summit. Have sent them an email just now as well, want to know why 2 way splitter jacketed female never fitted to male head joint(they had 2mm gap, basically female joint was too small and never had proper fit) plus while applying lube and rotating you can always feel off centred scratching unless you put too much of a lube that causes even bigger gaps in the joints (anyone had those issues?) while used Chinese setup before I had custom replaced all of the joints by a friend glass blower who put German high quality joints instead and never had any issues with leaking lube that resulted contaminating whole batch.
Also result came out slightly pink, not red, pink=\ used to have clear one. Also had 40-50 microns vacuum only due to micro leaks due to air escaping between joints washing out the lube(some had 1.5-2mm gaps in lower part where material bubbles by nature of distillation.
Used thermowell with 4 disks on it to have better separation but head temps never rose until had 200C + temps at mantle. I use Heidolf PIC controlled heater\stirrer with aluminum half sphere block on top of it to ensure proper heating with precision and no hot spots.
Please help, I am separating chemically converted CBD to THC and trying to increase d9 potency(best I’ve had was 60% D9 and 40% D8(lab tested).
Is there any way to do it right even with those faulty glass to avoid lube contamination and use of current setup?
pls find attached pics for your consideration.
p.s. my colleague placed plastic clamp instead of steel one - it melted, but never melted before since temps never rose that high and back pressure NEVER pushed our from the inside nor washed the lube.
Switched to 300C lube lab grade instead of using this Apiezon 250C(bs it melted at 200) overpriced sht.
Also first fraction that started to separate was around 170C at the top of the head but mantle was around 230=\ and resulting dirty was pink=\ always came out clear while used properly sealed china glass with replaced joints but never pink. Vac was at 40 microns next to pump reading and 50-60 after the splitter. Condenser was at 55C along with jacketed Y splitter using parallel condenser and rpm at 250 then ramped up to 300. I always measure temp of that aluminum block instead of oil.

@Roguelab - please help Guru
