Hello veeryone.. Does anyone know where I can get a decent small cryogenic freezer for about $2,000 (that is in excellent working order) that can be stored at one;s home?

Thanks John.. Although some of these ads cannot verify how well the items work.. I wish I knew someone well (in the field) who I know would give me a decent deal..

What temperature do you need the freezer to maintain and what is the size of the samples you need to store?

You need a dewar. There are no mechanical freezers that small that maintain that temperature.

If that is - 150 F which is -65 C then you can use a phase 3 electrically powered ultra low temperature freezer (can go down to -85 C). This is a very expensive fridge. If it is a - 150 C then as Brian suggested you will need a liquid nitrogen (LN2) dewar . This does not need electricity (no worries about power interruptions) but needs to be topped up with LN2 periodically either manually or automatically. The dimensions you describe mean it will still cost a fair amount. If it is a dewar you will need to also determine if you are going to store the item in the liquid or gas phase and also how you are going to bring the temperature down of your item before storage. You will also need other cryo paraphernalia such a gloves.

A good friend of mine keeps his dead bird in the regular house freezer. Its been in there for several years. Needless to say I don't eat hot pockets in his house.

Why does he keep his dead bird in his freezer? Does he hope to send it to a cryonics organization? This is actually a serious question.. The reason why I was asking about the freezer was because I am considering options concerning someday when my pet dies and he needs preservation.. Would it be cheaper (as a a struggling student - who is fully signed up himself for suspension) to temporarily preserve him at home until the funds can be raised to have him sent to an actual organization? but can home preservation be done effectively for a relatively cheap price?..around $2,000. Unfortunately, pets cannot get life insurance.. Thanks for listening..

Obviously, an at home preservation would be an inferior way compared to directly sending him to a cryonics organization.. But I wish there was more discussion on "decent" ways to temporarily preserve a pet - until funds can be raised in 10 years or so..

I'd think that it's the storage technique that's so important when it comes to preservation. If too much information is lost, there's no recovering it.

You might be able to hire a cryobiologist to come to your place, and use their technique on your animal, but that would be expensive.

At that size, you would have to have a thermos (dewar) and then refill it with liquid nitrogen regularly. This wouldnt' be economical over the long haul.

Is there a decent non liquid nitrogen way to preserve an animal? I was just reading up on the potentials of the freeze dry method..

Wow you're already signed up for cryonic suspension and your ~22y old or did you return to college at a later point? Don't know what I'm waiting for.
I don't think the home freezer is a useful approach. I'm sure the brain damage would be immense.
Do the organizations use the old technique or vitrification when preserving animals?
