Centrifuge w fritted filter

Fold it over the edge and screw the lid on. I flip the bag inside out, so the seam is on the outside. Less thca will get caught up.

You da man! Brilliant idea! Iā€™m going to try this in the morning for sure. We donā€™t have a rotor for our fuge that fits any of the fritted tubes so this is great. It also spins up to like 70k rpm so might have to try on the slower side lol

This is awesome dude, thank you for sharing this

Woah! Thatā€™s a really high speed rpm. Mine is literally labeled ā€œlow speed 4000rpmā€.

The main reason I wanted it was to see if I could isopycnically separate pigments in crude without solvent. The one rotor can run up to 500k rcf but we didnā€™t have much luck even at 96 hrs. But we only ran it maybe 2-3 times so Iā€™m not giving up yet.

@SidViscous Did you ever spin up some oil at faster than 4000rpm? Perhaps just make a quicker time of the job?

Beauty pics and tek Dred. Just to round it all out as Im not a rosiner, what bags do you use?

Oh yeah! I did one run at 60k rpm for 3 hours. It was very dark crude, it did appear to develop some sort of gradient but it was all so dark you couldnā€™t make much out of it. Also crumpled the tube pretty good so I kind of fucked up the gradient when I cut it open anyways

Edit: 60k rpm is around 200k rcf in that rotor I believe

Edit 2: these were not fritted tubes and also the oil did not have any diamonds in it, straight liquid oil. It takes about 15 minutes to spin up anywhere near that speed and another 15 to stop, if you ran the frit tek itā€™d certainly be done by then. Shit, if you didnā€™t break the frit youā€™d probably end up with sintered THCa lol

Rosin revolution bags. I think the 2x5 25 micron.

The Pyrex 8422-100 dimensions are 43mm diameter x 139mm length, make sure theyā€™ll fit in your rotor as replacements!

Very cool!!! If I could be as so bold to suggest an experiment; trying to crystallize/nucleate a higher grade high thca oil via centrifugal forces. One tube with a seed crystal, the other without.

I would imagine that you could probably get some pretty interesting crystalization because the THCa should band up by density and therefore supersaturate that section. My fuge is also refrigerated so you could probably figure out how to band/crash and maybe make a solid disc of THCa crystal. It would probably take a lot of experimentation though.

The other downside is that my biggest rotor only takes 250ml tubes and that one can only hit like 50k rcf which I donā€™t think is enough. I donā€™t have the right rotor but for like $2k I can run some 16ml tubes up to 800k rcf and if that doesnā€™t do it I guess Iā€™ll turn it into a coffee table like @cyclopath

I can definitely give it a try with some pentane

I got into a long argument once long ago on reddit about using centrifuge to nucleate and crystallize, I cited several papers directly about the matter to no avail.

If your just trying to crash out and separate vs grow stones it could be a more efficient path vs others, especially with the refrigeration capability.

The centrifugal force does add heat to the equation.

Like I said, I really want to get more time playing with it but my R&D time is very limited and I doubt Iā€™ll have a chance between now and the end of the year unfortunately

For butane/propane extracted solutions the centrifuge should impart a significant purging effect as well, no?

Iā€™m going to try my hand at this, just ordered a 100mlx4 centrifuge on amazon. I also already have 2x4 25u rosin bags that i think will work, just leave a little less over the lip than you did. I also have 15u 2x4 bags from a mechanical separation I did on a press, do you think those will work? Iā€™ll probably try it both ways regardless but just seeing if you have any experience, any feedback is greatly appreciated. Also do you have any pointers on growing the diamonds after separation? ITT it seems like people were suggesting to use pentane but didnā€™t really give any tech. Iā€™m only slightly familiar with BHO crystallization so Iā€™m not exactly sure what to do with pentane but I assume it would be a similar process.

The Amazon one takes a long time and looks like it was made in Russia. The eBay one is at least sleek looking. But, they probably have the same internals from the same guys.

Pentane is actually really easy to make large diamonds. But, in my opinion, Iā€™m not huge fan of them being all cloudy. But, you can grow some monsters with it.

Start at a 2:1 - 1:1 pentane:thca. I normally donā€™t recommend that one plays with pentane, unless they are in a well ventilated area

Ya you can

Are there any other solvents you would recommend that are relatively accessible? The ebay one you linked was gone, so I found a different one that says it has the same rpms as the one you posted not really sure what iā€™m looking for but time isnā€™t much of an issue if thats the only downfall. Most of what iā€™m trying to clean up has already been sitting for far too long so another couple days or what ever isnt going to matter much.
