Freezers?

[TooBigtoFail]

Walmart - Hisense 5 cu ft Garage Ready Chest Freezer, White, 33.6" Height, 1 Year Warranty, WFC050M6XWD. $165. -8F (-22c) near minimum setting. Will do -20F (-29c) at mid setting. Almost no frost buildup after 4 months. 80watts based on my Kill-a-Watt meter. Quiet. no fan. It use the outer shell to exchange the heat. Manufacturer states without power, keeps the temperature inside the freezer at 32F for 135 hours. I keep 40+ lbs of ice, lots of icepacks, over 120 vials, and some food. I shoved a Blink camera inside and the temperature varies by +/- 1 degree. Real happy. I think I reached colder than -35F(-37C) on max. And its made to operated even in a hot garage. I picked up at the store. Seems many get damaged during delivery.

My -80C ULT freezer is using 49W according to my UPS.

did you go new or used?

Used of course

You can't get a ULT25NEU model on eBay lower than about $1000 right now (that is working). You got a bargain on this one!

People are stocking up with peptides because of the upcoming changes to customs procedures. This is driving the prices of ULT freezers up

I’m not worried about China not producing it. I’m more worried about trying to get it into the US. I bought a used Lab freezer off eBay for just a little over a grand. I’m sitting on a 2yr supply right now at -80°C. Walgreens and CVS are getting rid of the freezers they used for the Covid vaccine. So many used freezers on the market. The freezers have a 10 to 12 year life. Most of them are 3 to 4 years old. The maker of mine is a Striling Ultracold 25L.

Is this the model that Walgreens/CVS are (or were) using?

I searched eBay and the Google and can't find anything in working condition under about $1k. Many of the vaccine freezer I am finding only go down to -20C (which my Amazon 1.3cu special already does).

Yeah, some of them were using this model. Back during the pandemic they were using anything they could get that could do -80. Yes, they are around $1000 used they cost over 5K new.https://www.ebay.com/itm/1869201914...wdawbt9qp6&var=&widget_ver=artemis&media=COPY

Are there any people here with a strong working knowledge of electricity? I purchased a small freezer (1.1 cf) that gets pretty cold (-10 f), but not lab freezer cold. My understanding is that freezing cycles are very bad for peptides. So I’m looking into getting a UPS to not interrupt the sleep of my peptides. How much backup power do I need to keep a 79 watt freezer operating for 8-12 hours? Is it possible with a UPS that is readily available to consumers?

If you can get it to withstand the inrush current from the compressor starting on the freezer, then it probably wont last longer than an hour at most for your consumer level 1500va ups (given the tiny batteries they use). When we size them for server racks, they start to get not only humongous, but down right expensive.

My personal solution was to get one of those "power stations" that a lot of generator companies are selling now as they are much cheaper and are general purpose. Originally, it was for short power outages where I didn't want to hook up the generator but I find it incredibly useful for other stuff like camping.

That's the one I have and doing some basic math, you should get ~11 hours out of it at 80 watts assuming continuous draw (not likely).

Mmh 4h with a "big" consumer UPS maybe, so you need one that can be extended like the SMX3000C with an external battery pack, but that's getting expensive lol

I got one of the -40 3.5 cubic foot chest freezers from Amazon for 300. It is holding at -45C. I keep the extra space filled up with cheap 80 proof vodka bottles. That mix freezes around -27C. So in theory the freezer should stay well below -20 or so till all that 80 proof is melted. Should give me a couple of days at least before anything thaws.

You could put your peps in a Thermos food storage container, I tested the 47oz model, it holds about 10 kits and it took about 5.5 hours to go from -5 to 32F. If you add a couple of ice packs to the freezer I bet you could get a few more hours out it. My 1.1cuft Amazon freezer will hold three of the containers. Add temp sensor that gives you notifications and you should have enough warning to fire up a generator.

Here is a link to the post I made with more details, after testing.

Good thread, needs more input from users. I have a zojirushi thermos coming and it's apparently the best on the market.

Those 3d printed peptide cases are a joke. It's finally time for proper storage methods.

I almost want to buy a Zojrushi food jar to check it's performance agains my 47oz thermos. I originally bought four of the Hydraflask 32oz food containers because others have made and sell 3d printed vial holders that fit inside them. I was very disappointed in their ability to keep the contents cold after removing from the freezer (only about 2.5 hours).

I think the 3d...
