Hello,
I am the lab manager at a university in Georgia. I am looking to add a preserved cuttlefish to our collection for students to study in lab. So far, I have had no luck at all locating one. Can anyone provide me with where I can obtain a preserved cuttlefish?

Preservative question

Paradox,

Does alcohol work as well as Formalin? I have a baby octo that I put in formalin (13% formaldehyde, I think, but also used about 1/2 water) that I would like to let my grandaughter take to school but am concerned about the preservative. If I can put it in isopropyl alcohol, I would feel better about letting her take it.

Also, since I have already used the formalin, is mixing a bad idea?

Steve's article says that once a big squid is fixed in formalin, it's OK to put it in alcohol:

Preservation
Following the month in formalin solution the specimen needs to be thoroughly soaked and the mantle cavity gently flushed with low velocity water to remove residual formalin and miscellaneous grunge. Three water changes are recommended. Thereafter the specimen can be transferred to preservative, one of either 40% isopropyl alcohol (my preference) or 70% ethanol.

Generally a specimen is fixed in formalin and then transferred to alcohol (either 95% ETOH or IPA) for long term storage and safer handling.

BTW in an emergency vodka or white rum works well!!!!!

Carolina Biological Supply and Ward's Scientific make a less toxic preservative that is safer for students. I don't know if they will sell to an individual though. They usually sell to a school or science based business. Formalin is a fixative, meaning it "fixes" the tissues so they do not decay. Alcohol can be used as a preservative (or fixative) that keeps "fixed" tissues from decaying. Alcohol is not as effective a fixative as formaldehyde.
