Ok, thanks. I do not know why this wouldn't be legal as it is very different from the cryogenic fluid itself, but I'll try to find out.

Very interesting !
I live in Europe so I think delivery won't be an option for me. However, I would really like to build one myself. It seems that you are using a cryptocooler from a superfilter, do you think this is possible to buy such a device in Europe ? Have you considered selling only the cooling device itself (I mean without the fan and the air duct) ?

These are similar to those yes, I haven't found any information as to if they're legal to export or not. If you have any related information I could probably reship you just the cooling unit itself.

You can sell it to cryoniks. Although its Frosbit does in less space. Sorry it was a joke.
Thanks for offering your product.

I think its legal to ship when you aren't shipping cryogenic fluid, thats technically a hazardous material.
I don't think the price is too high, just I don't have a use for it just yet, and I imagine alot of other people are like that, theres no point to buy it for playing around, its an industrial tool.
EDIT: I would put it on alibaba/aliexpress, I think you would get more hits.

Good unit for experimenting with high temperature superconductors

You say this unit will liquify natural gas?
Yes, easily - methane the main component of natural gas has a condensation point of approx -256F according to google, the cooling unit will easily reach -320F

Thanks for the interest, please note that this unit does not separate any gases from the air, the resulting liquid will have a similar composition to air (70% nitrogen, 20% oxygen, 3% argon, etc. )
If you can find a gas separation membrane or a machine that can concentrate gases from the surrounding air then you can condense liquids of higher purity.

now that's something I can get behind 
my company will be using liquid nitrogen for both cooling a 1 KW laser, as well as using nitrogen as a flue gas for metal work.
If your around in a year I may be interest sir.

After watching that video, I'm very interested! I spend $30-60 a month on ln2 as is, this could be a sweet way to save money.
I have you confirmed the liquid is nitrogen? It obviously acts like nitrogen, but have you used a probe to check that it is indeed -196C?
Do you have any units that are a bit more self contained? What is the power draw of the unit while running? And finally what was the volume of the container in the video? I'm curious to know how much that made in one day.

I don't have any equipment here capable of verifying that it is indeed nitrogen, but since the only way more gas can enter the jar is if what is already in the jar has condensed. To create a full jug of liquid it would need to be a significant portion nitrogen.
The cooling unit has several watts of cooling capacity at the temperature needed to condense nitrogen so it looks good on paper as well.
I ran the unit at 100W for the video (I think the max is 120W input power)
The jug is about 1-1.5L (not sure exactly, it came from IKEA) if you had a large commercial dewar you should be able to accumulate a significant amount.
It's very self contained as it is, I set it up in the video using just some pieces of scrap wood. A little extra effort and you could make it look nice and pretty. The cooling unit itself is all one piece, the only external parts you need are the variable AC power supply and the cooling fan.
Let me know if you're interested in me sourcing any of those parts for you and I can probably get them for a bit cheaper than the prices listed in the OP based on what I can find for sale.
Cheers

Good news everyone!
I found a new supplier of these things for much cheaper.
New price is 6.25 BTC + any addons as stated in the original post.

Bumping with video 
I can't seem to find any way to embed it so here's the link

Sadly, as much as I want this OMFG WANT, my wife has vetoed "more junk." 
Best of luck. Had I been able to get one of those in college, I would have been all over it. My roommate was much more tolerant of cryogenic liquids. We may have spent an afternoon with a styrofoam cooler full of LN2 at one point after discovering that, A, we could buy it, and B, it was dirt cheap.

Both questions are answered in the OP 
Unless you're talking about an actual lab grade dewar in which case you're at the mercy of ebay pricing.
Wiring diagrams and general instruction are available. Feel free to ask any questions

Could you also provide a dewar?

How many liters of liquid nitrogen can this produce per day?
May 26, 2013, 03:10:12 PM
Once I generate some more I'll do a quick video and post it here
