Zod update -- Pumpdown [Jul. 25th, 2011|04:11 pm]
Doug Ayen
Just got the quote from the Cryo folk: $225 to pump Zod down and NER test it. While that is more than I paid for it on ebay iirc, considering the current prices I find it quite attractive.

Over the weekend I mixed up the requested 30% bleach solution and gave Zod a good decontamination. Then this morning spattered grease on the outside. Sigh.

Since this place is about an hour drive from home, and they open at 8am, I'm hoping I can get my lazy ass up in the morning, drive over to Rockville and drop it off, and then get to work without running too late. It'll be good to have Zod back in working condition.

Sadly, mostly due to the weather and some health issues, I didn't get any real shop time in this weekend. I did greatly enjoy my lovely new AC system though.

*hugs* Glad the new AC help up to the heat. May Zod come through with flying colors. And may traffic flow in your favor.

If it's relatively new, then it should hold onto its contents for at least a couple of weeks. Zod didn't start losing insulation for over a decade, and really only started becoming unusable in the last couple of years -- and it was pumped down in 1992.

While it might help prevent dents and dings, I've managed to avoid those so far anyway. It would greatly increase the weight, which isn't good when I'm pouring some, what, 100 times at baitcon. 200? A lot, in any case.

perhaps a quilted jacket :) i was thinking mostly transport issues.

so if properly sealed/pumped, how long should N2 stay liquid?

When I first got it, a full tank would keep some liquid for almost 3 weeks. As of the last baitcon, that was down ot about 6 hours.
