These super interesting vacuum dual axis planetary centrifugal mixers for degassing/mixing/HTE separation/whatever things are cool. I want one.
Functional equivalents are sold by C1D1 Labs, Spin Tech, SpeedMixer, Hauschild, Thinky, Shen-Cing, Vasti, ZYE, GCT-Mix, and a bunch of other companies/brands.
As far as I can tell, the ones that are presently being flogged to y’all at a ~200% markup are made by Shenzhen Smida. Probably a TMV-1500T or TMV-1500TT.
C1D1 claim they’ve “done R&D” and their unit is “patent pending for the dual mode functionality” - which sounds to me they’re trying to get a patent on “we put a mesh basket inside your centrifuge basket” for which I would be willing to bet there is a non-zero amount of prior art, but patent trolls gonna patent troll, so whatever.
I don’t sell equipment to make a living - I don’t even like selling any of our custom equipment to my friends. As businesses go, it’s a time consuming pain in the ass, and unless you want to be a rapacious asshole and charge an obscene markup, or do super specialty custom stuff - or usually both - it’s not easy to make a living doing it.
But I hate watching people get taken advantage of. For what C1D1 / Spin tech charges for their oh-so special one, you can get the biggest unit that Smida advertises - it’s 10x the size - and still have enough left over for your local UL guy to come bless it. Or get what looks like the same thing from the same OEM, and have enough left over for a brand new Toyota Corolla.
After I commented in the last thread on the topic a number of you messaged me about doing a group buy type thing.
I’d planned on doing it if enough people piled in that I felt I could charge a transparent and reasonable markup and get one of the smaller examples of these machines for my own lab for something close to free.
At this point, I don’t think there are enough people that that’s the case. But there are a good number of y’all, so perhaps if anyone interested sticks their head in here, something could be worked out between everyone.
One problem is that it looks like most of you may want different sizes/models, and the economies of scale for manufacturers only really kick in once you’re buying a bunch of the same unit, so I’m not certain of how significant of a discount we could get.
Group buys are also a risky pain in the ass for the person doing them, because you’ve got to chase a whole bunch of people for money. If someone doesn’t pay the final amount for their kit, everyone else might be screwed unless they kick in additional funds.
Let the dumpster fire commence, or whatever.
