[Nhcoll-l] separating animals out in ETOH

Wed Dec 11 22:35:32 EST 2019

We have had mixed experiences with plastics submerged in ethanol over long periods, which is why we use glass and cotton. Some plastics behave weirdly after a couple of decades in fluid...

Hi Tonya,

In those instances we use plastic snap lock bags, either to contain the specimen plus parts, or just the parts (e.g. loose pouch young). We sometimes do that to collate loose labels as well. Usually we make small holes in the bags to allow ethanol to go through, but you still need to take care to ensure small parts can’t fall out. It’s easier to get the air bubbles out with the holes in the bags. In cases where the parts are too small to risk it, we just seal them up or put them in a vial within the container (usually a jar rather than a drum though). And everything gets a label inside as well of course.

I use mesh bags. They seem to hold up well in alcohol and are clear enough to see the label. It also makes animals easy to remove, and you can put in larger labels.

Hi all,

I think this came up recently, but I can’t find the thread. I’m looking for a way to keep individuals separate in one larger jar of ETOH (for various reasons it is sometimes easier than putting them each in their own jar). The fluid doesn’t have to be kept separate – the real issue is when there is either a) an animal its associated organ that has been dissected out or b) marsupials with pouch young that may fall out and get mixed up in the future. I would like to be able to put them in separate plastic bags or something of that nature, all in the one jar. Any thoughts or suggestions would be appreciated!

Cheers,

Tonya
