Hey man,
I’ve been following your threads a bit and sorry if I missed something. I see a lot of talk about 50mL tubes. However, we want to spin 750mL or 1000mL tubes. We have a few centrifuges from China we’re looking at and others from the pharma space(Eppendorf 5810) (I can some times get free or cheap used). I’m curious what the RCF/G needs to be at these volumes? Any help is greatly appreciated!
Same rcf.
Do you have tubes?
Solutions have been posted for 600ml. Maybe start back at the top of the thread.
Spin mason jars in a cheap bechmans with swing baskets from eBay with baskets from chemtek or rosin bags. Just pad them so they don’t shatter or make fancy metal ones like @cyclopath has shown
Say someone is using an L550 Fuge from Chemtek, with swing baskets. Would you be able to suggest an opinion on RPM max for glass Mason jars and size perhaps? Been worried about messing up the roto arm, with the stated 0.5gm off set for 4 baskets. It also states on this manual that a max of 300ml per basket, at 4000rpm and I have included that into the weight, including the container and filter type with product. I think certain glass was holding an avg of 1500rpm -2200/2400rpm I’ve read. Would like to know and feel safer spinning glass jars to max ability. While waiting for wide mouth metal jars and baskets, compared to plastic small mouth containers and fuge bags. Still so much learning and reading to do.
No glass over 1500… it sounds like a bag of marbles hitting the ground
Best I can tell the basket gets pulled down and the
walls of the jar come with it. Buy the metal containers
on there way. was a mis-order and using these small mouth plastic containers and 25mc fuge bags for the time being. The small mouth are just tedious on time efficiency and glad I read prior of “making shatter from diamonds”… 
Reading helped to refrain yet curious about “cusions”, that I noticed many make shifts and still curious about the max weight off set on the L550. Thanks for the reply and insight. Been spinning just want to figure our maximizing yields and time, till the metal wide mouth arrive. Small mouth anything is… if ya know, ya know lol…You know. haha
Ya the baskets and jars both break a little past 1500 rpm. I stay at 1200-1300 and baskets and jars don’t break. Little preheat in the oven at 44 c and it will clean up well.
To compare apples to apples though rpm is not enough. Different travel distances at the same rpm are not the same force applied. I use bechman Allegra 6s which have a bit higher circumfrence than the l550 so force is higher at the same rpm.

it lied to me…

Kinda makes you think
Is it “sinking in”…modest propaganda…now all we need is social engineering to transform the industry.

am I at the place?
Thank you!
Nice shop brotha!!!
Pictures or it didn’t happen
Yes dear bro.
Check out the picture of windchime tek.
Material column suspended in mid air much like solvent tank.
Were you not aware what that part of the extractor was called?!?
Hey there I do like what you’ve recommended but can you share your experience with what you’ve tried? This seems to be my bottleneck in Rexing and I hope someone has found a good option, I have the LD from amazon (not viking, I agree with @FicklePickle ) it works well but im running it constantly and I’d rather buy one that doesn’t run all day/night
I’ve broken glass jars at 4000rpm, it’s not catastrophic
It’s usually the metal baskets that go first and take out the glass, rather than the glass failing first.
I’ve documented a non-glass solution, and listed the rcf we are using.
Read.
Or just get in there and fucking try it.
I have read this whole thread cyclopath, your method seems a bit dangerous and personally I’d rather not go that route which is why I wasn’t asking you for a recommendation. I do see others have posted what they use (beckman or allegra) but those are only a few options. Either way I found an answer to my own question.
I found a website that sells used centrifuge and lab equipment.
I’m used to the concept that “dude, that’s dangerous!”…however, I’m constantly surprised to find myself the most safety conscious one in the room.
I don’t disagree that glass jars are not ideal, which is why “my” method does not use them.
Remember, once upon a time all centrifuge bottles and tubes were made of glass…
They work, and even when they don’t, it’s not that difficult to recover from…even made a thread so folks could explore that facet… How to turn "Shatter" into diamonds/sauce/distillate/anything I can sell?
Spinning a glass jar to destruction inside an Alu bucket is entirely different to spinning the Alu bucket to destruction.
The mass is contained. It has be redistributed, and will definitely cause an imbalance if you don’t destroy the jars in pairs, but it won’t hurt you or the fuge based on my experience and the huge number of other folks playing the same trick.
Have you read Separation Anxiety (mechanical)? Or Sauce Spinning for Carts 101 Video
Are you looking at the links below the first post in any given thread?
You’ve found someone who can sell you a fuge. I recommend you get one with self balancing built into the rotor. If you get one with 1000ml buckets, you’ll probably need to have bottles/cups/screens fabricated.
Why do you think I’ve showed folks how NOT to use glass jars?
Hint: G.seconds. It’s what counts. I recommend on the order of 5million
Thank you for the links and info cyclopath, I actually had not see a few of those links and I appreciate the knowledge.
Im thinking of staying under 1000ml if possible. The 600 seemed more reasonable, the LD3 with 50ml tubes works but sucks super hard with having to continually run it.
Yeah, my first response on 600ml buckets was to 3-D print inserts to hold 6x50ml tubes. Great, we can spin 24 of the fuckers, but this is stupid.
the cool kids are spinning jars
Yeah? That’s stupid too. Guess we ought should try it…
Take a canning jar with you…pretty sure it’s the 600ml buckets you’re after if you want to run the stainless cups I use OR the ones @Waxplug1 can supply.
Custom cups for 750 or 1000ml rotors are doable.
Most but not all folks are using swinging bucket rotors. You can definitely get the job done faster with a fixed angle rotor, but again, you need to custom fab the rest of the setup.
Oh shit. You weren’t asking me…
