Why do people always forget to factor in room humidity for storage

Posted by noderoom in General Discussion

I am honestly so tired of seeing lab logs where people act baffled by their lyophilized powders degrading prematurely when they literally leave the vials sitting out in humid air while labeling them. We talk about cold chain storage and proper reconstitution all day long yet basic moisture control during handling gets completely ignored. My latest batch almost got compromised because the desiccant packs in my storage box lost their color and I had to scramble. It is just frustrating seeing so many researchers waste good material simply because they treat storage like an afterthought. If you are not checking your humidity levels right next to your workspace you are gambling with expensive compounds for no good reason. I spent half my morning recalibrating my hygrometer and tossing out old packs. Am I the only one who takes ambient humidity way more seriously than the average hobbyist or is this a common oversight that everyone just sweeps under the rug until things go gummy?

Good catch on the color change of the packs. Most people just ignore that warning sign entirely.

What brand of hygrometer do you use? Mine broke down last month and gave me totally wild readings.

Wait do you use a glove box for handling or just do it out in the open air?

Are silica packs reusable if you bake them in the oven or should you always throw them out?

I never even thought about humidity affecting the powder before reconstitution. Does it ruin the structure instantly or over time?

Spot on. People spend hundreds on compounds and then store them in a bathroom cabinet or a humid kitchen.

I just work on a clean bench with a mini dehumidifier running nearby but a glove box would definitely be ideal.

You can definitely bake them to dry them out again as long as they do not have paper casing that burns.

Just a standard digital one from a local hardware store but I cross check it with salt tests every few months.

It happens gradually unless the seal is totally compromised and moisture gets inside the actual cake.
