Freezer Storage Question
-
I've read up on long term storage for peptides. Of course I get differentienting data because...well..."the internet will internet." I've read that a deep freezer or commercial/pharmaceutical freezer is the best option. I'm not interested in spending that kind of money for 50 vials of peptides. It's seems that the next best option is a manual frost chest (or standup) freezer due to the low and non flucating temperature. I currently don't have one of those. So for the last few months, I've just been storing my existing long term peptides in a hydrapeak in my refigerator freezer. However, I've read that this is not very good for the peptides becuase of the fluctuations in temperature due to the frost free process.
So to test, I setup two thermomentors. One sits alone in the freezer itself. The other sits in a hydrapeak with descicant packs. The attached graph shows the variances in temperature between the two. The blue line is the hydrapeak thermometer and the orange is the one in the fridge. You can see the swings in temperature of the freezer thermometer. However, the hydrapeak thermomoter has it's biggest variance of 4.3 degrees (-.6 degrees to -4.9). Most of the time is just a couple of degrees. Is that 4.3 degree swing, or constant 2 degrees, really enough to damage the peptides? It seems very small to me. Especially considering the stability of the humidity with the descicant packs.
I'm not opposed to spending the money on a manual frost freezer as they are relatively inexpensive. It's roughly about 8 years worth of peptides. I've only opened my peptide hydrapeak to add more peptides, and expect to leave it closed unless adding or removing as necessary.
Thoughts?

Great data. I store mine the same way. No educated experience on the details. My thought would be that that small of a temp variation in the hydropeak would be inconsequential. Especially all the data that has been shared on how robust peps actually are. Will be interested to hear from anyone that has actual data or experiments that have been conducted.

Heres Mine in a large Container in the fridge for the stuff I will be using the in coming year you can see spikes in temp an humidity when I open container

you need put desiccant in your container
-
First, where did you get those sensors from? And for me, I have one hydropeak in my chest freezer and one in the fridge (I access this one the most). With proper storage in the fridge, they should be good for at least a year. The only issue I have is with my hydropeak. The majority of the time it is hard as hell to get the top to unscrew. I mean, it's just awful. I need to find some food-grade silicone grease to lubricate that seal.

It’s the standard Govee Wi-Fi sensor. It’s a large container; I sacrificed a tray to put my sensor inside. (It still holds about 90 vials.) This one also holds a good amount of desiccant.

@MikeMiranda said:

It's a bunch of the .5 gram packs like you would put in a salt shaker. I purchased some of the 3D printed vial size desicant holders but haven't added them yet. I will, the next time I open it.

These are the Govee bluetooth, not the wifi ones that @mikemiranda mentioned. But I would recommend the wifi that he mentioned over these. Just keep in mind that the wifi appear to be a little bit bigger than the bluetooth only. I was hoping they would be small enough to fit without sacrificing much room. I was wrong. They are too thick for the hydrapeak inserts. @mikemiranda storage unit is much bigger. Besides the size, the main reason I didn't go with the wifi one is that I alread have a YoLink system for getting data while away from home. The YoLink system has both thermometers and water leakage sensors. It's just the system I chose before learning about the Govee.
I'm doing similar to you. I have one hydrapeak in the fridge for stuff that I won't touch in a while and 4 in the refrigerator for stuff to used within the year. It's overkill but I keep a little fantovo 3ml vial container for stuff I'm going to access in the next few weeks. It keeps me from having to open the hydrapeaks as much. A little OCD, I know. I agree with you that the hydrapeaks are little tough to open. I just look at it as having a good seal.

I have a few thousand vials on ice. I use the sensor below in two freezers at two locations. It emails me if there is a temperature fluctuation out of a range i set. It's a free service. I have wifi and internet on a ups system and the sensor as well. Its good for about 6 hours and in that time i would know if power is out by a temp shift.
I had a freezer fail and this told me otherwise i would have never known.
-
Also the intitial question. I did the same test with a similar sensor a while back. I saw 2 degree swings in the vault we used to sell and 4-5 degrees in the hydrapeak.
The swings arent going to ruin your stuff over a few years but I just opted for -20 deep freezers that need to be manually defrosted every few years.

When you say a FEW years, what's that estimation? 3 or 4? Anything longer may become suspect? I know it's not possible to pinpoint an exact timeframe. I'm just looking for a safe guideline of numbers to go by. Like I mentioned, this allotment is approximatley 8-10 years worth. If the guideline is 3 or 4 years in a refrigerator freezer and 5-10 years chest freezer and infinity in a deep -20 degree freezor, I have something to guide how my stashing for the future will proceed. I'm trying determine if it's overkill to buy a chest freezer for a relatively small amount of vials, or possibley just not stash so much for the future. Please excuse my harping on more concrete numbers. My OCD tends to seep out from time to time and it's pain the a$$.

I think you could actually store vials in the Tupperware that comes with it; just leave room for desiccant.

I have a Apache 2800 that hold 36Kits (Desiccant holder an temp sensor took some space) that will be my freezer stroage eventually
@MikeMiranda That's a fantastic idea for storage. Gotta love Harbor Freight. I have two of the Apache rifle cases and love them!

I just got back from Costco. They have a Frigidaire gravity convection refrigerator/freezer (separate compartments) for $230. I wish I had got that one for peptides.
