I dont know the tare weight of the can itself. Anyone know what these cylinders weighed from DuPont? There is no obvious "tare" stamp like other cylinders have, but I have the following off the can:
DOT 39 NRC 260/325 M1079
WT2030A (or WJ2030A..cant tel if it was meant to be a T or J). Figured some old timer here would know somethjing on this, or how to go about finding out. I can always try to call Dupont, of course.
Thanks, Men.

Weren't these 30 lb. net wt. R-12? Most seemed to have TW stamped on them.
Should be able to find the answer in this link.

Thanks, TRB, but no luck there so far.

Really I thought I read someone list them at 6 or 7 pounds.
-------------------------
Put the cylinder in a cold place until the contents are completely cold. Then take it out into normal warm humid air. It should start to condense "sweat" on the outside. The sweating will clear off of the top part sooner than the bottom where the liquid is. At some point in the warming process you should see a clear line showing the level of liquid inside. If it doesn't sweat you should still be able to feel an abrupt temperature change at the level corresponding to the liquid line.
Second post in the second link within the link I posted on tare weights. But I don't think all cylinders are going to weight the same.
-------------------------
My mistake as I read your first post not the header of this thread.
-------------------------
The DOT 39 50 lb disposable cylinder we use for Genesolv SF has a TW of 11 lbs.
-------------------------
Okay, admit to living in the backwoods, but never ran across a 50 pound cylinder, they do call them cylinders, don't they? Largest I have ever seen in the last, hmmm, let's see, 46 years is a 30# cylinder, seems terrible to have to toss those things away when empty. Cost a lot more than the damn refrigerant on the inside, least manufacturing wise, the rest of it is a government ripoff. Just heard on the news yesterday that 80% of the government supported day care centers were ripping off the government in Milwaukee County, nice to know where my money is going. Love to see our governor and legislators all in jail.
Nick, you can go here and look at non refillable cyclinders If you click on the PDF specs the blue is 15 lb, the white and red are 30 lb and the green one is a 50 lb. The size is actually the water capacity. No TW specs provided.
-------------------------
Yeah, I see they manufacturer four different non-recoverable cylinders and spec capacity by water weight in the 15-50 # approximate range with no cylinder net weight given. Suppose a guy filling a skyscraper AC could use a 50# tank. Just never seen one. Would have to find the density of the liquid refrigerant to learn the true capacity of these cylinders. Didn't mean to pick on my state, but they do charge a surtax on all refrigerants, claim they are protecting the environment. But we also have Michigan, Minnesota, and Illinois nearby and so far, no border inspections. Maybe next year.
Hecat, how did you verify that my bottle is 11lbs....curious?

I purchase 50 lb containers of Genesolv SF from Honeywell. They contain 50 lbs of product and shipping weight is 61 lbs., thus the simple answer of 11 lb TW. Genesolv is Honeywell's trade name for precision cleaners and Genetron is their trade name for refrigerants. I am going by our warehouse this morning and will see what numbers I can pull off a full tank, and I will see if we have an empty one in our shop that I can weight; will post back later.
-------------------------
The tanks I have are marked DOT-39 NRC 260/325 M1144. There is no manufacturer or TW markings that I can find. An empty container here at the shop weighs 10 lbs. The additional 1 lb covers the box.
