Dewars...

Here is some pictures of my dewar. It is a 35L stainless steel. I purchased from black hole surplus. It seems to insulate good. The level was about the same at the start of my runs on saturday as it was at end of my runs on thursday night. It did not come with a lid though. Some suggest a tennis ball but the opening is too large for that. Any ideas?

A withdrawal device would be nice as it is pretty difficult to pour when on the bottom half of the tank. It is heavy and a pain to lift into my truck when full or move up and down the stairs to my basement (where I bench). I am glad that I didn't get the 50L. It lasted for 4-5 hours for two nights (8-10 total.)

Matt made one out of foam, I am looking around right now to find where to get a large block of it. Michaels online doesn't show a piece large enough to make one and I don't know how well gluing pieces together would hold up. I don't know the opening size on yours, he told me on the phone mine was about 3 1/2" ID. The tracking is saying its suppose to be delivered Friday so I will know more about it then.

Looks awesome

Wish I could get one cheap, as LN2 is a lot easier to get than DICE in Denmark

As promised since this is a show us your Dewar thread. Also I would like to add this Dewar came from Blackhole also and was extremely fast shipping and they are great to talk with on the phone.

Your dewar is very shiny

Meathead · Mar 7, 2011

Have you used the dewar yet? Been lookin for a 30-50l dewar but with a draw top so I don't have to tip it.

CgS Drone · Mar 7, 2011

I haven't used it yet, wont have a pot for a couple weeks it looks like. This one is 25L's the one Super has is 35L's. I will go down to the pluming supply and get me a 4" to 2" flexible reducer to put on the top of the Dewar to reduce the size of the outlet to help me be able to control the pour a bit more since the opening size is 3 1/2" ID.

Nice dewars, what do those run used, the website they have is somewhat archaic, and what does LN2 cost?

ln2 varies wildly by region.

Prices are $200 for the 30L dewars. We also have 50l available. They are $250. Shipping/Handling is about $100, depending upon how far we ship them.

supposed to be cheaper if you call em though

CgS Drone · Mar 8, 2011

Your best bet is to call. I emailed and got one quote and called the next day and got a better price. They are very friendly on the phone and will take the time to go over anything that you want to talk about.

Super about $13 for the cone and half hour taking my time. Got the cone at Michaels.

You may be able to buy the smaller cheap cone I cut a lot off of this one so its 5" at the base in the pic. but I wanted to make sure it was still 3" round at the top. I bought one of the cheap $10 hot wire cutters to make it, you can borrow that if you want when you make yours.

I put my dewar up on the edge of a plastic tote and on a wood block so I could tilt it easy when the level was down below 1/2. I went upstairs for dinner and the edge of the plastic tote bent down while I was away from it, and the 1/2 full dewar fell over. I stood it up. Barely any LN2 spilled. I stood it up and left it until today. I left work early to do a little more benching. When I looked at my dewar it had condensation all over it and the LN2 was gone.
Upon inspection ( camera phone in top). I see this. I believe a weld on the inside cracked and let the vacuum out ( or air in ?)

We should get this for the Benching partys

Would take care of the lack of cold storage

Hey we could even hide a few bodies in there if someone snaps and starts "stabbing people in the eye with a soldering iron"... Cookie for the one that tells me what movie that comes from..

Well, I just upgraded to a 50L. Blackhole had a good one in stock.
Between that and my watercooling stuff I have been buying, I have now blown my BD budget.
I guess I have couple months to save up though.
