Piecing together a small SPD - what do you think?

And if it’s packable this would slow down the vapor path and allow for better separation for such a big bore column on a small boiling flask.

Im leaning towards a 45/50 straight head myself that I can put some packing in for small runs


#122


Holla!


#123

I wouldent add packing to that head, the vig section takes up too much space for that.
The column would be “flooded” and your seporation would be poor.


#124

I’m getting these 2 mixed up. The smaller vigreux area head is not 45/50 joint it’s 34/45

it looks packable and possibly a better head than the 45/50 head overall. In my search for 1 china head to rule them all from maybe 500ml up to 5L even. ha

24/40 on top could use a thermowell adapter for taking vapor temp. 29/42 at the drip tip and 34/45 main Joint, it looks pretty large ID all the way through. and the 24/40 joint on top is a nice big opening to stuff media into.




#125

yes one is packable, the other isn’t.


#126

The one with the three different sized joints is funky! Thats alot of different joints going in there!


#127

lol well i guess we get what we pay for! uniformity is not a strong suit of these cheap chinese heads

Is the consensus here that distribution valve and single collection flask is better than a cow and multiple collection flasks?


Doing a short path run tomorow.. smell question
#128

Hell yeah, smoke them if you’ve got them!


#129

You guys have me wondering if I have the right size head now… I have this one:
https://labsociety.com/lab-equipment/short-path-distillation-head/#variation_description

It’s the V1 head, but doesn’t have any info on what size flask it will work with. I’m assuming I’m ok with my 1L flask…


#130

your fine @munkdooligan. We are on the chinese cheap path…your set with your american head. LOL


#131

Lol bro I’m just deciphering as much as I can with the cheap ass Chinese heads. That ls head is in a different league


#132

Have you figured out what you’re going to use for the thermometer adapter for the BF and head yet?


#133

Yup! I have a 4-channel data logging thermocouple thermometer.

The Craigslist package came with a chemglass inlet adapter, which I intend to use at the BF with this K-type thermocouple probe I ordered: https://www.amazon.com/T-PRO-Sheathed-Thermocouple-0-1000℃-Compensating/dp/B074375LJR/ref=sr_1_16?rps=1&ie=UTF8&qid=1547443993&sr=8-16&keywords=thermocouple+probe+k+type+stainless&refinements=p_85%3A2470955011

Thinking I’ll seal it tightly with PTFE. I also got this K-type thermocouple wire to put between the flask and the mantle: https://www.amazon.com/Perfect-Prime-TL0700-Thermocouple-Thermometer-Temperature/dp/B01MU29Q3Z?ref_=bl_dp_s_web_9751332011

And then for the head I got this ptfe adapter and thermocouple probe:

And finally I got this totally unnecessary probe for the cold trap because I had a free channel on the thermometer lol:


#134

@Killa12345 @square_root_pharms Ok cool, thanks for the reassurance lol. I tend to worry about the details of things… good thing I’m in a legal state and have easy access to quality cannabis :rofl:


#135

Ahh, thanks for that. That PTFE head adapter looks like it will fit the bill perfectly. :+1:


#136

What is the best way to connect gl lines? Will PTFE tape and an appropriate hose clamp suffice?


#137

they should have a sealing gasket at the face, no tape is needed.

A small hose clamp or twist of wire is usefull to retain the hose.


#138

Dont twist too tight, you’ll break a GL glass joint very easily.

I’m special.


#139

I’ve broken the plastic ring like that too!


#140

Great thanks! Yet another thing to buy haha
