Guest TheMadDutchDude Posted March 26, 2016 Share Posted March 26, 2016 Hey guys, I have one of the above that came with my dewar a long time back. It still works, but the valve which you use to let the LN2 flow is a little loose so it leaks when it gets really cold from the LN2 flowing through it. Besides that, it's pretty much golden. What do these go for? I'm not looking for maximum profit, just a fair appraisal that you guys may pay for such a thing if you were in the market for one. Thank you in advanced!

xxbassplayerxx Posted March 28, 2016 Share Posted March 28, 2016 What types of dewars does this fit? Is it made by Taylor Wharton or someone else? If it's TW, do you have the glass/plastic tubes? Was it made for use with a 25LD, 35LD, etc.? As with all things cryo related, they're generally much less expensive than retail. For example, I think Taylor Warton sells their WD device for $800 or something but it sells on the second hand market much closer to $150, sometimes less. The relief valve getting stuck is a very common issue on these. It can usually be replaced and will fix the issue. Link to comment Share on other sites More sharing options...
Splave Posted March 28, 2016 Share Posted March 28, 2016 $75 - $100 Id think is fair. I find that the withdrawl device wastes alot of ln2 even on my 50L I just use a foam top now and pour it Link to comment Share on other sites More sharing options...
Guest TheMadDutchDude Posted March 28, 2016 Share Posted March 28, 2016 That's perfect, guys. Thank you! I'm not really sure who makes it, Bass. I'll have to take a closer look at it and then I could tell you more. It's for a 50L dewar, so I am assuming that it is a standard/universal neck size. I could be wrong, though. Splave, same here! I've been put off of it for that exact same reason. It just wastes LN2 and I'd rather that was getting wasted in the pot. Link to comment Share on other sites More sharing options...
ObscureParadox Posted March 28, 2016 Share Posted March 28, 2016 Told you ages ago to pour *cough cough* Link to comment Share on other sites More sharing options...
Guest TheMadDutchDude Posted April 6, 2016 Share Posted April 6, 2016 Told you ages ago to pour *cough cough* That is what I do once I am ready to use it, I don't actually use the device. I was using it as a stopper, but that was a big mistake and I realised the error in my ways. Link to comment Share on other sites More sharing options...
