Ran across this beast at a local machinery auction house. It sure puts the deep into deep-freeze. -123 deg F sure should do it.

Fully stainless interior, with 4 separate shelf doors. Two 1hp compressors and weighs in at about 800lbs. Even has a mechanical chart recorder to insure your frozen veggies never thawed! No yellow energy tag but I calculated ~$700 a year at 10 cents/kwh.

These were likely $10,000 new, knowing this auction house I wager it goes for under a grand. It has 3 bids and stands at $4 at this time, auction closes tomorrow!

That's what you would really call a Kühlschrank!!!!

I had an old Scientific Products catalog (don't even remember where or how I'd gotten it; the Science Geek that I am surely may have gotten it from a teacher in Middle School!) which was actually FISHER Scientific and had an Explosion-Proof Fridge in it, and may have even had a Super Freezer such as this one, too!

Reminds me of the Kelvinator at a hospital pharmacy I'd worked at for keeping cold prescriptions in, too...

Lab supply-could it be used for freezing organ and tissue samples to run them thru a "microtome"(machine for slicing frozen samples thin enough so they can be examined under a microscope)The microtomes have a freeze chamber in them to keep the sample frozen while it is being cut.They are interesting machines-the microtome knife sharpeners for them are more so.The microtome knives were sharper than a zazor-so the specimen sample wasn't distorted while being sliced.

Never used a 'cooled' microtome. We would either wax-impregnate or freeze-dry AND wax-impregnate samples before sectioning on a room temperature microtome. Saying that, our college had very limited funds.... :(

It never ceases to amaze me how diverse the conversation topics can be on what is, after all, a 'washing machine' site. :-)

All best

I have seen the refrigerated microtomes in lab catalogs and a hospital lab.It was being used in the lab-and watched it working-and the blade sharpener,too.Some tissue samples had to be frozen-the wax would contaminate them.This was in a hospital in Rapid City,S.dak about 35 yrs ago.Will have to look up "microtomes" on the web today and see how much,if any they changed.I was going to do the lab type thing-but electronics sidetracked me.

I watched the auction close, winning bid was $4 dollars!!! I considered it, but didn't want to deal with transporting and selling it, although if one found the right buyer $1000 should be easy. Heck scrap value is probably as much as $150-200 with all the stainless...

Very much the same here, Tolivac... Was aiming to be a Medical Lab Technician, then suddenly I was a G.P.O. comms engineer....

$4!!!!!!!!!!!! What a steal!!! Probably cost too much to post to this side of the 'pond'... :-(

Dave-yes,the labwork was looking interesting--but when they were examining a gangrene leg-had other thoughts!!Then the electronics "bug" bit!!Now thats what I do.The lab thing would have been sort of interesting gross things aside.

we had only wax-medium microtomes to use when I took Cytology and Histology in college, but big research labs also used cryogenic (refrigerated) microtomes, or cryomicrotomes. The latest microtomes use femto-wavelength lasers instead of mechanical knives to do the actual sectioning.
